The Pit HD 1080p 

I did that many times as a kid, in the late 50's and early 60's. Found all sorts of interesting critters. :D

Haha those jars are pretty clever. I've used the same technique to trap unwanted pests inside my house. Pretty cool catches though, I find millipedes in my plants containers outside in my garden quite often, they seem to be pretty abundant in my backyard.

NIce. Word of caution - learned from experience - pit traps fill up with water when it rains, and that can have bad consequences fro anything it traps. A roof might help with something small like a jar, but I've had a nightmare with the bucket traps I've been checking as part of my job. I put small drainage holes in the bottom thinking that would solve the issue - but the trouble is that if the water table is very high, water actually comes up through the holes instead of draining out of them. Fortunately the buckets are being used to catch newts, and they love a bit of water, but it can be a pain to see them if there's 6 inches of muddy water in there.

At about 3:58 there is a tiny spec of a bug that crosses the frame. Compared to the spider, it's as small as the spider is to a human (or PZ :). There are also yet smaller organisms that you can't see with the naked eye.

this is so cool thank you!

What were the wolf spiders doing with their pedipalps? Looked like they were drumming.

One of those large spiders looks an awful lot like an Australian funnelweb!

Put a layer of sand (or flour or talcum powder) around the burrow and try to identify the footprints.

What was the behavior where the spider was vibrating its palps in what anthropomorphically looked like a pensive mood?

Combflowers? Which species are they do you know please? Not one I'm familar with. (Aussie typing here.)

Put on a hat.

don't know if you have seen this before, but this looks like a really well done 3d animation of spider internal anatomy: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-JpuqwfKR66U.html thought you might like it.

Oh how the mighty have fallen. Myers, who once aspired to be the Fifth Horseman, reduced to studying spiders in his backyard. Didn't Milton say something about one of the pleasures of Heaven was watching your enemies in Hell?
