#Arachtober 26: the cool weather is back and so the clover mites (_Bryobia_) are out! The tiny juvenile spiders plentiful now seemed unbothered by the crowds of mites scrambling around them.

This time of year where I am, checking under Queen Anne's Lace flowers is a great way to find cool bugs. All found in the same clump:

- jagged ambush bug (_Phymata_) with fly prey
- long-jawed orbweaver (_Tetragnatha_)
- swallowtail caterpillar (_Papilio_)
- running crab spider (_Philodromus_), in the same flower!

Put together a video of the long-jawed orbweaver making her egg sac! https://youtu.be/Ntymw7nCpuI

It's a mix of still photos and video segments, and much of the video is kind of repetitive, so see the timestamps in the description or use YT's chapter feature to skip ahead if you like. Or watch the whole thing for the immersive experience, I guess.

BTW, here's what a long-jawed orbweaver egg sac looks like when complete. (I had to go home before our gal upthread was completely finished with hers, but got a pic of this fresh one by a spider who was making hers at around the same time.)

On another tree I saw a courting male _Tetragnatha_ exuding a drop of semen onto a loose tangle of silk, then reach down and grab it with his pedipalps (the short appendages on either side of his jaws). In mature males, the palps are complex organs that are used kind of like turkey basters to inseminate females. I'd never seen this at all in any spider!!

Marked sensitive because, well, spider semen.

Long-jawed orbweaver (_Tetragnatha_) making her egg sac, a tufted ball suspended from three strong lines between walls of willow tree trunk.

I see these egg sacs all the time but was unsure who exactly was making them, so when I saw this _Tetragnatha_ laying down the three silk lines I decided to watch!

A bit of #OpenAccess #Arachnews:

How do forested buffers around rivers affect the diet of predators like trout and spiders? In the abundant fall season, both get most of their food from terrestrial sources! I'm not sure exactly what this means because ecology is really hard so read the paper yourself: https://www.sciencedirect.com/science/article/pii/S2352249623000319#s0040 :OpenAccess:

Two new species of eyeless, cave-dwelling pholcids described. One is from Australia's ancient Pilbara, a remnant from before Australia aridified. Another is from lava tubes on Réunion Island. Plus some philosophical questions about what a cave is, really. https://subtbiol.pensoft.net/article/105798/ :OpenAccess:
