I went to my first volunteer work party at Mount Pisgah Arboretum yesterday. We were removing false brome, an invasive grass, from the forest understory. Not only was it fun to hang out and share stories with the other volunteers while we used our saw-bladed "hand sickles" to cut the grass out of the soil, but I found all sorts of wonderful critters living in the duff. This critter was the most exciting discovery of the day:

I found it scurrying around in the soil after I lifted out a big clump of grass roots--it first tried to burrow away, but then just held perfectly still (a sketcher's dream). My guidebook at home pegs it as a forest spider wasp,
Priocnemis oregona/ It's a parasitic wasp that hangs out in shady areas of leaf-litter, looking for burrowing spiders that it paralyzes with its sting, then lays its eggs on. Wow. Very much a miniature
tarantula hawk (same family of wasp, similar glorious iridescence, though this one has metallic blue-black wings and a red abdomen, sort of reversing the t-hawk colors).

The other dangerous forest resident we found was, of course, poison oak. I know how to identify it when its leaves are out, but it was great to get a lesson in recognizing the bare stems in early spring as well. (Distinctive yellow-ochre tint to the wood, sharp angle of the pink-tipped buds, hint of vine-like behavior...) We'll see if my new observation skills mean that I won't have a rash break out over the course of the next few days.
(Pardon the mud stains on all these drawings, by the way--proof I was working, not just doodling. *grin*)
