  Jeremy Tatum writes:   A few weeks ago I had the idea that I’d like to post pictures of both sexes of both species of our local Malacosoma, so I reared six caterpillars of each.  Darn it, but all the M. disstria  turned out to be females, so I didn’t get a guaranteed picture of a disstria male.  So, here is my incomplete (and hence not all that useful!) set. (One of the caterpillar photographs is Rosemary’s)
