Found winged webspinner under loose bark in woodpile near where I found same-sized wingless one a few days earlier. There were web tunnels evident. Here the two are compared, with a major question being, "Are they the same species?"

They differ in color, head size, and length of both the antennae and the double do-dads on their posterior, although I probably shouldn't refer to them with such highly technical terminology ;-) Do these differences signify different species or merely sexual differences?
