Helping out with a Night Hike at the Texas Butterfly Festival last night, I found this Flattie on one of the attendees. We had a really good time. We saw lots of spiders and I got two new moths species.

Crescent-eyed Spider (Genus Selenops)

Happy All Souls' Day! Continuing with spiders, it's only fitting to post a Ghost Spider.

This is a ghost spider from the genus Hibana. They earned their spooky name from their pale, semi-translucent bodies and their incredibly fast, phantom-like movements.

Happy All Saints’ Day! Saint Felix of Nola, fleeing persecution, hiding in a small opening in a wall. A spider spun a thick web across the entrance, hiding him from pursuers. Because of this miracle, Saint Felix is considered the patron saint of spiders.

I noticed a quickly shutting tiny door. I pried it open to see this set of legs. Only good shot I got. Possibly a Southwestern Trapdoor Spider (Eucteniza relata). First trapdoor spider I have found. Found in South Texas.

Green Lynx Spider (Peucetia viridans) with a moth. I am trying (not very successfully) to not post the same species too often, but I love the depth and detail in this shot so I had to share it. #Arachtober #spider #arachnid #naturephotography #macro #macrophotography #stereography #stereopair

I wish I had better depth on these, but with the cha cha method of shooting stereo, its near impossible because a few are always wiggling between frames.

#Arachtober 12 - Small Grass Lynx #Spider with huge egg sac. Lynx spiders guard their eggs but I wonder why it was at the end of a leaf. Lynxes don't carry their egg sac, but some will move them if necessary. Looks like Oxyopes acleistus, I think. South Texas USA #macrophotography #naturephotography
