I saw a severe infestation of Army Worms in Riding Mountain
National Park (Manitoba) in 2001, and I will never forget it. The
air was filled with the sound of the caterpillars munching leaves -
as pervasive a sound as Spring Peepers. It was impossible to walk on
the trail to the observation platform at Lake Audy to see the Bison
without stepping on writhing masses of them, crunching underfoot.
Ugh.

At the risk of confusing you readers further: Of our two species of tent
caterpillars, only one is a tent-former. Malacosoma americanum is
the Eastern Tent Caterpillar, and the caterpillars communally spin a tent
of silk in a crotch between two or more branches, not in the
foliage. But the Forest Tent Caterpillar, Malacosoma disstria, is
mostly found as solitary larvae; however, it/they are known to march
communally and to aggregate on tree-trunks, but never form a tent or
silken nest. <br><br>

<dd>No. Tent Caterpillers occur in spring and early summer, the two
species are Malacasoma disstria and Malacasoma americana. They are
Lasiocampids closely related to the silkmoths. The Fall Webworm
occurs in late summer. the species is Hyphantria cunea a Tiger Moth
(Arctiidae)<br><br>
