Hi Angus & All, Aug 17, 2013
Although they are abundant here infrequently (the last 30 yrs ago ?) =
the genuine common name here is also Army Worm. No common name of folk =
origin will tack tent onto something that does not make tents.
Until you brought this up, I had forgotten the connection between =
the two names. I notice on the internet that there are several =
armyworms; M. disstria not among them.
Yt, Dave Webster, Kentville

spectacles of them covering buildings, roads, & "marching" across crop =

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.=20
Cheers from Jim the Other, in Wolfville.
