The isabella moth=92s woolly-bear caterpillar is black at both ends and =
brown in the middle. I think the myth says that the amount of black is =
related to the severity of the winter (or the opposite??), but I read =
somewhere that the relative amounts of black and brown are related to =
aging of the caterpillar.
Regarding Don MacNeill=92s note, I think I have seen the same =
documentary showing the arctic woolly-bear caterpillar (all one colour, =
sort of reddish brown), which is another tiger moth like the isabella =
moth (family Arctiidae) =97 decades ago Dr. Olga Kukal at Acadia Biology =
Dept. studied the arctic species in the high arctic (why is arctic =
usually capitalized by everyone?), perhaps at Lake Hazen? And she =
determined that this particular caterpillar requires 14 =93summers=94 in =
order to grow enough to obtain the size and nutrients for forming a =
pupa/cocoon and then an adult moth, before laying some eggs and starting =
over. The documentary claimed that this life cycle was much shorter, =
about 8 years?
Cheers from Jim in Wolfville.=20
