- Help identifying this spider (Austria)
Found this big chonker in the garden, about 4-5cm big, never seen anything like it here before. Any ideas what it could be? : ) Thanks in advance!
- Need help identifying spider (MI, USA)
We just moved to Michigan and these are all around the property (including the basement). Just want to know if it's something I need to be concerned about. Google lens is inconclusive, at least with my non-existent knowledge.
- This Spider Uses a Light Show to Trick Eager Male Fireflies Into Its Webwww.nytimes.com This Spider Uses a Light Show to Trick Eager Male Fireflies Into Its Web
In China, the arachnids seem to somehow manipulate the flashing of a caught male firefly to resemble a female’s come-hither signal.
- Whip Scorpion, Cambodia
Since they are found in the same places as Scorpions, these always creep me out. Once I see what it is, I shoo it elsewhere. As long as they are handled gently they don't release that defensive stink. Scorpions here readily act defensive, these are much more relaxed. Their colouration is quite interesting.

The arachnids, which are not spiders, were thought to have only two eyes, compared with many more on spiders.

Our collective arachnid aversion could be causing us to overlook something even scarier: Spiders may be disappearing.

- A pair of Joro spiders, Trichonephila clavata, caught mating
Of particular interest is the extreme size discrepancy between male and female in this species. This was also one of the largest females I've ever seen!

Sometimes you can't decide between beauty and horror, so you just walk the line!
- Bird-dropping spider, Phrynarachne katoi, central Japan
I recently came across this lovely(?) crab spider on a birding excursion. The bird-dropping spiders of Phrynarachne are apparently not only visual but also olfactory mimics, for all intents and purposes attempting to fool both predators and prey. Apologies for the slightly subpar image quality; I didn't have my macro lens and had to improvise.
- Can you help identify this?
Found it on my son's hair after a 10min visit to our veggies garden. My guess is that it might be a tick but we are not in an area of lime disease and although it's an open, rather unkept, field the only mammals I see around are 2-3 stray(?) cats.
The photo was done using a stereoscope+smartphone. The dark lines underneath are .4 to .5 mm.
Any pointers would be welcome.
- Tarantula mid molt
Here's another old picture from my vault. This is one of our Greenbottle blue tarantulas (Chromatopelma cyaneopubescens). We spent the day watching this little guy molt from start to finish and took pictures of the whole process. You can see in this picture that he is laid out on his back on his molting malt. At this stage he has split from the carapace lengthwise down the sides and is currently pulling his legs out of the molt. We had two at the time and wanted to breed them but they both turned out to males.
- Another mom showing off her babies (Centruroides ochraceus)
This one I took about 12 years ago in Yucatan. I was inspired to post it because I saw other photos of arachnids showing off their babies ;)

- Arachnid has three versions of 'male:' How leg morphology predicts which versionphys.org Arachnid has three versions of 'male:' How leg morphology predicts which version
Long-legged arachnids called harvestmen are "trimorphic," featuring three types of males. University of Auckland research is giving some clues as to how that happens.
- What's the best food for an audacious jumping spider?
I have a large terrarium where I grow various types of moss. I keep springtails in there to handle any mold that pops up, but some creature (fungus gnat larvae?) was killing off the springtails. So I captured a jumping spider, thinking it would gobble up the fruit flies/larvae. The fungus gnats have disappeared, so it seems like the spider might have done the job, but now I'm worried about it getting hungry.
I gave it a mayfly a couple days ago, and that evening it was sitting in the corner of the terrarium like a toddler with a juice box, so it obviously likes those. Are there any specific things that are good to feed it, or can I give it anything that I catch that isn't predatory? For example, would a "regular" sized moth be dangerous? It'd be like 2-3x the size of the spider.
