Chapter ii
THE SPOTTED LARINUS
Larinus is a vague term, which cannot teach us anything. The word sounds well. It is something not to afflict the ear with raucous spittings; but the prentice reader wants more than this. He expects the name to give him, in euphonious syllables, a brief description of the insect named. This would help to guide him in the midst of the vast multitude.
I cordially agree with him, while recognizing what an arduous task it would be to devise a rational nomenclature that would give the beasts the forenames and surnames which they deserve. Our ignorance condemns us to be vague and often nonsensical. Let us consider a case in point.
What does Larinus mean? The Greek lexicon tells us: Λαρινός, fatty, fat. Has the insect which is the subject of this chapter any right to such a description? Not at all. It is corpulent, I agree, as are the Weevils generally, but does not more than another deserve a certificate of obesity.
Let us look a little deeper. Λαρός means pleasant to the taste, pleasant to the eye, dainty, sweet. Are we there now? Not yet. To be sure, the [[19]]Larinus is not without daintiness, but how many among the long-nosed Beetles excel him in beauty of costume! Our osier-beds provide nourishment for some that are flecked with flowers of sulphur, some that are laced with Chinese white, some that are powdered with malachite-green. They leave on our fingers a scaly dust that looks as though it were gathered from a Butterfly’s wing. Our vines and poplar-trees have some that surpass copper pyrites in metallic lustre; the equatorial countries furnish specimens of unparalleled magnificence, true gems beside which the marvels of our jewel-cases would pale. No, the modest Larinus has no right to be extolled as superb. The title of dandy must be awarded to others, in the beak-bearing family, rather than to him.
If his godfather, better-informed, had named him after his habits, he would have called him an artichoke-thief. The group of the Larini, in fact, establishes its offspring in the fleshy base of the flowers of the Carduaceæ, the thistle, the cotton-thistle, the centaury, the carline thistle and others, which, in structure and flavour, recall more or less remotely the artichoke of our tables. This is its special province. The Larinus is charged with the thinning out of the fierce, encroaching thistle.
Glance at the pink, white or blue heads of a Carduacea. Long-beaked insects swarm, awkwardly diving into the mass of florets. What are [[20]]they? Larini. Open the head, split its fleshy base. Surprised by the air and by the light, plump, white, legless grubs sway to and fro, each isolated in a small recess. What are these grubs? Larinus-larvæ.
Here accuracy calls for a reservation. A few other Weevils, related to those whose history we are considering, are also partial, on behalf of their family, to the fleshy receptacles with the artichoke flavour. No matter: the species that take the lead in numbers, frequency and handsome proportions are the authorized exterminators of the thistle-heads. Now the reader knows as much as I can tell him.
All the summer, all the autumn, until the cold weather sets in, the most ornamental of our southern thistles grows profusely by the roadside. Its pretty, blue flowers, gathered into round, prickly heads, have won it the botanical name of Echinops, in allusion to the Hedgehog rolled into a ball. It is indeed like a Hedgehog. Better still: it is like a Sea-urchin stuck upon a stalk and turned into an azure globe.
