To quickly assess the difficulty of the text, read a short excerpt:
The greatest number appear at about IP. M. Their season is from the middle of June to the middle of September. Their whole object in the butterfly state is the perpetuation of the species. The males arc smaller than the females and greatly more numerous. They seem to have special ren- dezvous to which the males always resort first, and wherever the mules resort a female may be expected; they seem almost to know beforehand where a female is to appear above ground; indeed merely touching a female... is enough to cause the males to settle on one's hand. The insect is readily caught, par- ticularly tho females when just evolved from their pod; they are then too heavy for flight; as many as 400 eggs have been taken from one of them. The eggs are laid anywhere, on anything on the surface of the ground, and at any distance from the trunk of the vine, though eftener near to the trunk. Later in the season the young grubs can be detected along the small roots, gnawing their way under the bark towards the trunk, which, by evolving time, is pretty well shorn of all its roots, large and small, and if new roots have not pushed out above the infested ones to keep the vines alive for an- other season, the plant must die the same year.
