Not a caterpillar

Pine sawfly larva, homePine sawfly larva, home

With the start of the orthopteran chorus, the aural signature of midsummer and beyond, I've been adding an after-dark walk to my repertoire. I don my headlamp, affix various kinds of lights to the camera, and comb, at the very least, the plants growing around the yard for whatever kinds of arthropods are busy working the night. I found this handsomely marked critter munching a pine needle, and while my first guess was caterpillar, the fact that it had very different kinds of true legs should have pointed me in a different ID direction. Ultimately, the fact that it didn't appear in Dave Wagner's caterpillar guide made me remember the sawflies, a kind of thick-waisted wasp whose larvae resemble adolescent lepidopterans. This is, not surprisingly, a young White Pine Sawfly, and while members of Neodiprion pinetum can cause a lot of damage if they're present in high numbers, I spotted very few. As long as the youngster doesn't call in lots of friends, I guess I'll just leave it alone.
