"Cow-spit, Snake-spit, and Frog-spit"
IF I have been asked once I have been asked fifty times to explain the secret of that frothy, bubbly mass which clings to the stems of grasses and weeds in the summer meadows. Surely no one of our readers who has spent a June or July in the country can have failed to observe it. Even as I write, having just returned to my studio by a short cut across a meadow near by, my nether garments plainly show that I must have come in contact with five hundred of them during these few rods. In the height of its season this frothy nuisance monopolizes many a meadow. No one, unless most ordinarily clad, would care to wade through its slimy haunt. Certainly no stroller in his "Sunday best," having once experienced its unpleasant familiarity, would willingly give it a second opportunity.
Its name, I find, varies in different localities, but all, for obvious reasons, have the same salivary significance. In various parts of New England, for instance, it is known as cow-spit. In the southern States the snake is held responsible for it, as is shown in the popular name of snake-spit. I have frequently heard it called frog-spit, cuckoo-spit, toad-spit, and sheep-spit, and doubtless many other local terms of the same sort may be found. The cow-spittle theory, however, seems to have the greatest number of converts. Let me, at least, hasten to expose this miserable slander on "our rural divinity." Have, then, our cows nothing better to do than to go expectorating all over the meadows, road-sides, and hay-fields? And how busy, indeed, they must have been to so thoroughly cover the ground, to say nothing of their surprising aim, every glistening cluster of bubbles being landed not helter-skelter on the leaves and flowers, but only on the main stems of the various plants upon which they are found! Even in this little field outside my studio window, which is thus generously moistened, what a task! Why, it would certainly have taken at least ten cows in industrious expectoration to have left it so profusely decorated as now; but the fact is, there is not, nor has there been, a single cow in the field.
Only a few weeks ago I received a letter from an Ohio boy who, among other things, wanted to know what those slimy "gobs" on alders came from. He said they called them "snake-spit" out there, but that he had seen lots of them higher than any snake could get, unless it was a "racer," meaning the blacksnake, which, as is well known, is fond of climbing trees and bushes. And later came a letter from a lady in Lewiston, North Carolina, who had looked deeper into the matter, and whose inquiry throws a little light on the subject. She writes as follows:
"An old subscriber to 'Harper's Young People' desires to express the pleasure which your articles have afforded.... I have just finished the last, and have been out to examine the faded primroses, but only a long-legged green spider rewarded my search. Too late for our season." The readers of "Young People" will recall my article about the beautiful rosy moth which lives in the faded evening primrose, and which was the quest of the above writer, who further continues: "I do not think you have written about what is called here 'snake's-spittle,' a frothy exudation, perfectly white, surrounding a small speckled beetle (I suppose). I found several on my chrysanthemums about two weeks ago, but they seem to have disappeared now."
This supposed "small speckled beetle" lets out the secret of our "cow-spittle." The old cow is acquitted, and also the snake, who has enough mischief to answer for.
Each of these masses of bubbles is seen to surround the stem, upon which it clings, out of consideration to the popular tradition, spitted through the centre, as it were, with its culm of grass or branch of bramble or weed. But the true expectorator is within, laved in his own froth, his beak embedded in the juicy stem, and his suds factory continually at work. We have only to blow or scrape off the white bubbles, and we shall disclose him, even though he makes considerable effort to dodge out of sight, either in the remnant froth or around the stem. But it is not a beetle that we at last bring to view. It would be hard, indeed, for any one but a naturalist to decide on so short an acquaintance precisely what to call him. He is green and speckled in color, anywhere from a quarter to half an inch in length, depending upon his age, and somewhat to be anticipated in the extent of his show of suds. He is wide of brow, has rather prominent eyes, and tapers off somewhat wedge-shaped behind.
To the bug student these features are very significant, and he is not long in placing the creature among his proper kindred. He has a sucking beak, which connects him with the tribe of bugs, and other features ally him to the cicada, a humble though accomplished relative of the buzzing harvest-fly or hornet. He dwells in cool contentment here in his aerated bath, but he has not thus put himself to soak as the end and aim of his existence. Erelong he will graduate from these moist surroundings, and we shall see quite another sort of being, whom we would not dare to affront by the mere mention of such an ignominious, foamy existence. Here is one of them, which has just flown in around our evening lamp, and has settled upon my paper as I write. Not a strange coincidence, by any means, for others very like him have been there before when I have been writing on various other topics, and are the certain representatives of that nocturnal swarm which is always attracted by the light.
What a pretty atom he is as he rests here on my paper, clad in his bright emerald green, and only about a quarter of an inch in length! Let us catch him for our cabinet. But this is not so simple, for, like the proverbial flea, I put my finger on him, and he isn't there, but is to be seen yonder, at the farther edge of the table, the instant I lift my finger-tip. And there are others like him scattered about me beneath the lamp, one especially with four brilliant scarlet bands on his bright green wings, a near relative, though I am not sure at this moment whether he dates back to such a soaking as his little emerald fellow just described. We must be quick indeed to catch him, he is so alert; and while his entire visible emerald anatomy consists of a pair of nimble wings, no one would guess it now, for he certainly does not use them as he speeds here and there on our table. No, he has still another resource in those powerful hind legs of his, which soon take him out of our reach when he concludes to trust the spring. Here, then, is one of the host of midgets who are responsible for our soiled garments in our summer walks—the "frog-hopper," or "spume-bearer," in his perfection. The round of his life is thus given in Harris's beautiful volume, "Insects Injurious to Vegetation":
"The 'frog-hoppers' pass their whole lives on plants, on the stems of which their eggs are laid in the autumn. The following summer they are hatched, and the young immediately perforate the bark with their beaks, and begin to imbibe the sap. They take in such quantities of this that it oozes out of their bodies continually in the form of little bubbles, which soon completely cover up the insects. They thus remain entirely buried and concealed in large masses of foam until they have completed the final transformation, on which account the names of cuckoo-spittle, frog-spittle, and frog-hopper have been applied to them. The spittle in which they are sheltered may be seen in great abundance during the summer on the stems of our alders and willows. In the perfect state they are not thus protected, but are found on the plants in the latter part of summer fully grown, and preparing to lay their eggs. In this state they possess the power of leaping in a remarkable degree, and for this purpose the tips of their hind shanks are surrounded with little spines."
The "spume-bearer" (Aphrophora) this insect has been called, and the peculiar method by which he turns out the froth on the stem is well worth a little study. He makes no secret of the process. If we take a grass stem, remove him from his liquid lair, and transfer him to another stem, we may witness a novel method in the preparation of suds. And a busy little factory it is, too, when we consider what a continuous demand is made upon it, caused by the sun's evaporation through the long summer day. A single mass of bubbles with its tenant removed quickly disappears. If the little insect is permitted to crawl upon our hand, he is apt to try the new domicile. I have never been able to induce him to continue up to the suds point, but have no trouble in locating the place where he begins operations.
The Paper Wasp & His Doings
FEW of our common insects enjoy a wider intimate acquaintance with or a more respectful recognition from humanity than the wasps and hornets. Their acquaintance, with that of their yellow-jacket bee and bumble-bee relatives, is forced upon most of us at a tender and impressionable age, and leaves a lasting reminiscence. Having once been interviewed by a hornet, do we not remember him for life for his pains?
The bee has perhaps given us equally pointed excuse for respectful, or rather disrespectful, consideration, and yet how different is our attitude to the bee in contrast with that towards the hornet! Why? The discrimination is largely a matter of sentiment, but especially a matter of ignorance; sentiment as associated with fragrant flowers and droning wings and "white-clover honey"—for do we not all know the "busy bee," and how he "gathers honey all the day" for the hive, and thus for humanity and the hot biscuit? There is then a palliative for the busy bee's "hot foot," as Paddy described his first warm contact with the insect. But who ever heard of any one with a good word for the hornet? He is under the ban—an outlaw, the black sheep of the insect fraternity, a source of uneasy suspicion, shunned by valiant man, good for nothing to the boy except to shy stones at from a safe retreat; while to the fair sex, always the signal for precipitate flight, if not hysterical terror.
The popular verdict on the hornet is so well voiced in that famous entomological essay from the pen of Josh Billings that I am tempted to quote it entire and use it for my present text. I am sure the average reader will say "Amen" to every word of it:
"The hornet is a red-hot child ov Nature ov sudden impreshuns and a sharp konklusion. The hornets alwus fites at short range and never argy a case. They settle all ov their disputes bi letting their javelin fly, an' are az certain an' az anxious tew hit az a mule iz. Hornets bild their nest wherever they take a noshun to, an' seldum are asked to move; for what good is it tew murder 99 hornets an' have the one hundred one hit you with his javelin! I kan't tell you just tew a day how long a hornet kan live, but I kno from experience that every bug, be he hornet or somebody else who is mad all the time, an' stings every chance he kan git, generally outlives all ov his nabors."
An artistically constructed paragraph, with a "snapper" at the end of it, or rather a "sharp konklusion" quite consistent with its subject.
"Mad all the time," he says, and "stings every chance he can git," and such would seem to be the unanimous belief. Indeed, the phrase "As mad as a hornet" has passed into a proverb, which presumably dates back to the Aryans, or at least from the scriptural allusion of the providential visitation of hornets, which routed the impious inhabitants of Canaan before the conquering Israelites. The ancient Greeks and Latins are on record in their appreciation of the "warlike hornet," and considered that it came rightly by its valor as an inheritance from the dead war-horse from whose carcass the insects were supposed to be spontaneously generated.
"The warlike horse if buried underground
Shortly a brood of hornets will be found."
writes Ovid. Another author, Cardanus, thought that a dead mule was the more likely source, which recalls the above erudite allusion of hereditary instinct of Billings.
Yes, if time-honored popular prejudice is to be accepted, the hornet is always on the rampage, always spoiling for a fight, always "mad"; and considering how many thousands of them there are abroad, and what opportunity they have of mischief, it is a wonder that poor humanity is able to put its nose out of doors with impunity.
Let us see how far this bad reputation is sustained by the facts. What is this black paper hornet (more properly wasp) doing from morning till night? Buzzing among the flowers, creeping over the bruised apple windfalls in the orchard, whirling and dodging about the window or fence or side of the house, or perhaps darting in our faces as we sit at the open window.
Two episodes which I recall, in which this white-tailed black wasp from the big paper nest was conspicuous, occur to me as I write, and as the two stories, taken together, will show us the true character of the suspect, and what he is up to all day long, I will narrate them.
The first instance is vivid in my memory. It occurred in my boyhood—my boyhood? how many another boy remembers the same incident. That same hot day in August, that same cool, shadowy swimming-hole in the brook, that same gray paper nest on the overhanging branch a few rods up stream? What a tempting target! How the stones flew as, safe up to our necks in water, if need be, we pelted the paper domicile! And now a lucky throw has gone straight to the mark. With a crushing thud the stone has penetrated the side and knocked off a piece of the gray wall, which falls to the stream below, exposing the tiers of paper comb, as a whirling, buzzy maze, like a swarm of bees, enshrouds the mangled house. Ah, what fun! How we laughed at the sport!—for at least ten seconds. Then the tide turned, and how gladly had we possessed the art of the bull-frog, and buried ourselves in the mud until the storm blew over, for the "mad" warlike hornets were upon us. The red-hot child of Nature "was now at short range," and "stinging every chance they could get." "When you see a head hit it," seemed to be the plan of campaign, and of course the heads had to come up once in a while, and erelong were considerably enlarged, principally through inoculation, but let us hope with wisdom as well.
"A mad hornet, and only at a little boyish fun! Look on this picture, and now on this."
I have shown our hornet under exceptional circumstances, when anger may be a positive virtue and a means of grace. Following are some of the every-day capers, which have not helped his reputation, as I observed them on the crowded porch of a summer hotel in the White Mountains several years ago. It was in September, and about twenty guests, mostly ladies and "summer girls," were assembled in a quiet social convention.
Suddenly there was a scream, as one of the fair ones, with a frantic, vigorous stroke of uplifted fan, distorted face, and a cross-eyed glare, clutched her roll of fancy-work and fled to the house. "Did he sting you?" asked her friend, who readily followed her in the door. "The horrid hornet!" she exclaimed. "No, he didn't sting me, but he would have done if I hadn't hit him just that minute. He flew right at me in the ugliest way!" The words were hardly out of her mouth when another scream was heard, followed by a general clearing of the piazza. There were now two or three "mad" hornets making themselves generally promiscuous among the guests. At the last general alarm one gentleman, an old bachelor, who sat tilted back in his chair near by, remarked, with an expression of superior disdain at such a silly exhibition of feminine weakness: "Why, ladies, the hornet won't sting you if you'll only let him alone; he has been buzzing around here for an hour, and hasn't stung anybody yet."
At this moment, as fate would have it, the roving hornet chanced to buzz around the speaker, and with a distinct object and deliberate aim plumped itself against his nose, amid a roar of laughter from the gentlemen present, and the complete discomfiture of the victim, who lost his balance and toppled over sideways upon the floor. He was now glad to follow the ladies in-doors, and enjoy the fun at his expense. "Well, it might have been expected," he remarked, "after the way you have all been screaming and banging at him. You have got him mad at last, and the innocent spectator has had to suffer in consequence."
I chanced to be sitting within a few feet of the surprised bachelor, and had observed the incident. Indeed, the hornet had once or twice struck me forcibly upon my coat sleeve and shoulder. Concluding that the incident suggested an opportunity for a little pedagogic enlightenment, illustrated by an object-lesson too good to be entirely lost, I sauntered into the hotel parlor, and did what I could to relieve the hornet from the unjust aspersion on his character.
"Did he sting you?" I asked.
"No, he didn't," replied the victim, who, like the ladies whom he had ridiculed, was more surprised than harmed; "but he tried to, and I concluded not to give him a second chance. He struck me so hard that if his sting had happened to hit me, it would have penetrated my skull."
"And can you imagine a hornet failing in his intention when he gets such a good square shot as that?" I asked, further.
"Well, no," he replied; "but perhaps his venom had been expended on the ladies; by their screams I judge most of them must have been stung a half-dozen times apiece."
"If you will step out on the porch a few moments," I proposed, "I am assured you will soon be disposed to offer your apology to the industrious and innocent insect which you have so libelled."
A cautious group soon assembled at the doorway of the piazza, and at my suggestion closely watched the antics of the hornet, which was still apparently as mad as ever, in the absence of human targets, seemingly "working off his mad" by butting his head against the clapboards along the side of the building. After a moment or two of this exercise, with a quick curvet, the insect betook himself to the roof of the piazza, where he disappeared among the bordering vines. A little cautious search soon revealed his hiding-place, however. He was hanging, head downward, by one of his hind legs, twirling some dark object in his front feet; and it needed only a little closer examination to disclose this object to be a fly, which was gradually being reduced to a pulp by the sharp jaws of its captor—a morsel, doubtless, soon to find its way to the cell of a baby hornet in some paper nest close by.
"You will now doubtless understand that precipitate onslaught on your nose," I remarked to my bachelor friend. "Rest assured that the attraction of that aquiline member alone would never have caused the panic that ensued; but you did not give our hornet the credit for the removal of that pesky fly which had been annoying you for so long, and which is even now being masticated into an unctuous pellet in some secluded corner of the piazza, or is perhaps being borne on buzzing maternal wings to the little white grub in the hornet nest yonder in the pines."
And this is all there is to the "mad" of the hornet. He is generally not half as mad as are his detractors. He is simply minding his own business, and is as busy as a bee in his own way; and if his critics will only mind theirs, there need be no fear that he will try "konklusions" with them, or even give a hint of his "javelin."
This curious episode may be witnessed by any one who will take the trouble to closely observe the wasp. The sunny side of the barn or stable is generally the favorite hunting-ground, and any one who will spend a half-hour in following the efforts of a single wasp will have to admit that he earns his living, for it is not every fly that is caught napping, and that white face, with its eager, open jaws, must needs butt itself against the shingle many times before its quest is satisfied.
But the warlike hornet does not always content himself with such small game as a house-fly. Big bluebottle-flies are a frequent prey, and juicy caterpillars are a welcome variety in his daily diet. Even the butterfly, with a body nearly as large as his own, falls a frequent victim, the scimitar-like jaws severing the painted wings in a twinkling, either during flight, or falling one by one from its dangling retreat.
The life of the black hornet, or wasp, may be briefly summed up. The females survive the winter, and in spring build a tiny comb of papery material composed of saliva and timber scraped from old gray boards and fence rails. In each cell of the comb an egg is laid, which soon hatches into a minute white grub, the sides of the cells being continued to accommodate its growth, the comb being gradually inclosed in the paper covering and enlarged as the nest cells are increased. The grub at maturity incases itself within its cell by closing the orifice with a silken veil, and soon turns to a chrysalis, and in a few days emerges as a perfect wasp. Several broods are reared in a season, the combs being extended in several layers, each suspended by a single stalk from the centre of the one immediately above. A single nest sometimes presents as many as six or seven tiers. But the nests are much more safely examined in winter than in summer.
