Hokkaido Bug!
Location: Taiki-cho, Hokkaido, Japan
March 22, 2012 3:02 am
I live in eastern Hokkaido, Japan, in a small farming village. The other day I found some bugs I had never seen before in my bathtub, and then, when I left my apartment, saw literally hundreds on my apartment’s walls and windows! I have never seen these bugs before, and I’ve lived in Japan for over 3 years now (and I’ve even encountered Asian giant hornets!) This was the best picture I could take of them. They are over 1cm long.
If you could help me out that would be great!

Hi Regi,
Just because there is a large population of an insect does not mean it is an infestation or some other bad portent.  This is a Stonefly and the larvae or naiads of Stoneflies are aquatic insects that can only survive in unpolluted running water like streams and brooks.  The fact that there is a large population of Stoneflies is an indication that the water in your area is relatively pure, so take this spring swarm as a good sign.

Half dollar size hairy spider
Location: Orlando FL

I’ve seen these spiders at my house before. They are really hard to photograph becuause they only come out at night and they build large webs high in the air. This year there are two of them within 5 feet of each other. They have been building their webs every night for the last week or so. By morning the webs are gone and so are the spiders. The bodies are about the size of a nickle and with the legs at a normal distance they are about the size of a half dollar. The legs could sprea out to about 4 or 5 inches I would Imagine.
They have been building their web between my house and my neighbors house it’s about 15-20 feet. Here are some pics and a video.

What are they?

Wheel Bug Nymph

Dear Andrew,
WE have no shortage of Wheel Bug photos in our archive, but we cannot resist adding your photo to our site because of its dramatic simplicity.  Wheel Bugs are Assassin Bugs and they might bite if carelessly handled.

Dear Bugman,
I’m used to seeing katydids of various shapes and sizes here in Costa Rica, but they have all been some shade of green. I was taken aback when I saw this pink one on my balcony this morning. Is this a mutant? I put him on my flowers for a photo and noticed him eating the flowers which are also his color. Is this color a result of his diet? Just curious. Thanks.

Pink Katydid

Dear Jori,
Pink is not an uncommon color variation in a North American Katydid,
Amblycorypha oblongifolia, which your specimen greatly resembles.  Here is a photo from BugGuide and we have numerous examples in our archive.

anatus formicinus eating unidentified caterpillar
Location: Toledo, OH

Afternoon, Bugman.
Ran in to this guy while chasing snakes (to photograph, not to harm) and didn’t have the heart to lift the wood he was on to follow my snake friend. Pretty sure it is anatus formicinus, but after half an hour of digging around I can not identify my caterpillar. Ah well, it was still a wonderful sight!

Running Crab Spider eats Caterpillar

Hi Katy,
We believe you have correctly identified this Running Crab Spider, though we are correcting the spelling of the genus name which is
Thanatus.  There are some photos of Thanatus formicinus on BugGuide that look very similar.  We believe the caterpillar is most likely a Cutworm or Noctuid Caterpillar, or possibly a relative of the Tent Caterpillars, but we haven’t the time this morning to do that research.  This is a thrilling spring Food Chain image.

Nevada, WCTA insect survey
Subject: Nevada, WCTA insect survey
Location: Las Vegas NV adjacent to Red Rock Canyon National Conservation Area

Hi Dan – two students just found this insect at the end of our class. It looks like a springtail (Collembola) to me and possibly the genus Siera. Sorry the picture isn’t better, but I think it’s good enough. It was picked up off the ground. Very small @ 1mm at best.

Hi Bruce,
Springtails are the most common Hexapods on earth, and this does appear to be a Springtail.  We cannot say for certain if it is the genus Seira (note the spelling correction) but we are linking to the BugGuide page on the genus.  Not all Springtails have the furcula, a forked structure that allows them to spring into the air, but your specimen appears to have a very well developed furcula.
