词条 | tent caterpillar moth |
释义 | tent caterpillar moth ![]() The eastern tent caterpillar moth Malacosoma americanum of eastern North America deposits its eggs on a tree in midsummer. The egg mass appears as a shiny, tarlike band on a branch. The following spring the eggs hatch, and the larvae migrate to a fork in the tree and construct a large silken tent that, in most species, serves as a communal web. The larvae leave the nest each day to feed until early summer when they are full grown. Pupation occurs in cocoons of silk mixed with a yellowish-white powder. The forest tent caterpillar moth M. disstria is common in the southern United States. The family Lasiocampidae also includes the eggars, named for their egg-shaped cocoons, and the lappets, having lateral lobes, or lappets, on each segment of the larva. |
