On the same plate, fig. 12, may be seen several varieties of the objects known to fishermen as “Caddis” cases. These are residences built by the larva of the common Caddis, or Stone-fly, which is represented on the same plate, fig. 9.
Still keeping to [plate F], and referring to fig. 1, is seen the horrid-looking Water-scorpion, a creature which, though it does not sting, has much of the scorpion nature, and so bites. Fig. 1 a shows the same insect as it appears when flying.
At fig. 3 is seen the Water Boatman, so called because it lies on its back, which is ridged like the keel of a boat, and then rows itself about by means of its middle pair of legs, which closely resemble oars.
Fig. 5 shows a very curious object which is common enough on the margin of pools, and runs on the surface of the water as if it were dry land. When alarmed, it shuts up all its legs, and looks just like a piece of dry grass or thin stick.
Another insect much resembling it, is the common Gerris, seen on [plate I], fig. 6. It may be seen on every pond or still water, running over its surface, and is furnished with wings wherewith it can fly to great distances. I have found specimens on the tops of hills, far from any water, and hiding under stones out of the sun’s heat. Fig. 1 shows the common May-fly.
All gardeners have been annoyed with the curious production called the Cuckoo-spit. This proceeds from the larva of one of the hoppers, and on removing the frothy substance, the little soft, greenish insect may be found within. The perfect insect is shown on [plate C], fig. 1 a, and the exudation itself at fig. 1.
There is another hopper seen on [plate B], fig. 2, called from its colour the Scarlet Hopper. It is common enough on ferns, and may be found chiefly in the open spots of forests where ferns abound.
On [plate J], fig. 7 a, is the common Green Grasshopper, as it appears when standing; and on fig. 7, the same insect as it appears when using its wings.
The common Earwig, [plate I], fig. 8, is introduced for the purpose of showing the very beautiful wing which this insect possesses, and which is seen expanded at fig. 8 a.
