Astylopsis macula (Lamiinae)

Found a bunch of these flat-faced longhorn beetles on a dying tree a few weeks ago. I’m fairly confident it’s Astylopsis macula. But there are a gazillion genera of Lamiinae, so I’m happy to be corrected. Would also be very happy to hear from anyone who knows what elytral pits do, other than providing handy identification. I’ve wondered about that for years. Are they vestigial patterns from forewing ancestry? Sound-dampening trick to elude echolocating bats? Are pits just decorations, useful in crypsis or for intraspecific recognition? If you know, would love to hear from you.

Creepy blob of resin on a tree

While searching for yellow brain fungus on a hot day in December, I stumbled across this twisted little blob of gunk nestled in a bark crevice. At first I was all excited that it might be some sort of snow fungus (e.g., Tremella fuciformis) that was past its prime, but I’m pretty sure it’s just resin, gum, or sap — not sure which. But I’ve never seen resin with little spheres blebbing out, and nothing with a white membrane. It’s creepy. If you have more information or have wild speculation, please send me a note or leave a comment. Approximately 1″ long. Photographed at Lake Mohonk, New Paltz, New York.

I really had wanted this to be a slime mold … perhaps an immature Trichia or Stemonitis. If you’re a slime mold fan, please weigh in.
