Small winter stonefly

I was out looking for the elusive snow fly yesterday but found this, instead: an eastern stonefly (Allocapnia recta), a member of the Capniidae (small winter stoneflies). At least that’s what I think it is. Larvae are active during the winter, and adults can fly and mate even when temperature is in the teens. Pretty incredible to see them flitting around on a cold day when other insects cannot even move. At Hildacy Farm in Media, PA. Probably emerged from the nearby Crum Creek.

Moth Night photographs

I’ve been out mothing before (with my dad and his moth friends), but I finally made it to an official National Moth Week event this past Saturday at Natural Lands Trust‘s Hildacy Farm Preserve. It was raining so there wasn’t a great turnout (by the moths), but below are several photographs from the evening.

To set the scene for those of you who haven’t had the experience: we had a flood light, a mercury vapor light, and a blacklight set up next to a couple of white sheets. Any one of them would work just fine, but the more light the better, in general. Even a cell phone screen can attract moths.

The large moth in silhouette above is a Pandora sphinx moth (Eumorpha pandorus). I think the person is entomologist Tanya Dapkey of the University of Pennsylvania. Bigger photo of the moth is below.

Here’s a copper underwing (Amphipyra pyramidoides), one of two that I found on a tree far away from the lights. E.g., you can go out at night with a flashlight and find moths just hanging out.

This moth was also just hanging out, avoiding the rain. I think it’s a spotted Phosphila (Phosphila miselioides).

Just in case you want to start planning your own Moth Night, National Moth Week will be July 22-30 in 2017.

Nursery web spiders (lots of them)

Here are some photographs of a nursery web spider (Pisaurina mira) along with approximately 75 newly hatched spiderlings. She guards the hatchlings until they are older. The adult was a thing of beauty, especially when viewed large so you can see the hairs. There was a red milkweed beetle head on a nearby leaf, and the plant itself was devoid of anything but spiders. Hunting spiders like this one probably don’t help monarch populations.

I’ve never seen them do it, but apparently the adults are completely comfortable on water, and can even submerge themselves if threatened. They’re related to fishing spiders, so that’s not a complete surprise.

Photographed at Natural Lands Trust’s Hildacy Farm Preserve in Media, Pennsylvania. I can’t find any information on whether this species is native to North America, other than finding it listed on invasive.org. The species also is distributed in western Europe.
