My daughter took this picture of a 5-inch-wingspan moth resting on a window in central Costa Rica (near Monteverde Cloud Forest Reserve). This was taken today (end of October). The picture has been rotated 90 degrees counterclockwise. You can see part of the head on top.
Closest I found on an identification site was a ”black-witch moth” but the pattern seems a bit off.

Owl Moth from Costa Rica

Owl Moth from Costa Rica

Dear Tomas,
This Owl Moth,
Thysania zenobia, is a gorgeous specimen.  We wonder if a bird took a piece out of its wing.  You can verify our identification on Project Noah.

Thank you, Daniel!!
Yes, I noticed two pieces gone on the right side and thought the same.
Went to project Noah but landed on someone else’s picture.  Not sure how to “verify”.   I will try again to figure it out.
Thanks for your work

Water Strider

Water Strider

Dear TRay,
We wish we had more photos of Water Striders on our site.  They are amazing true bugs that spend their immature phase skating across the water in search of prey, especially insects that fall onto the water’s surface.  When they attain adulthood, they are capable of flight.

Hi
My friend and I were walking across the driveway at our house at 7:30p in Los Angeles. This bad ass was on the pavement. What the HECK is this?? Some sort of queen bee termite? It was pretty big- at least an inch and a half long and with that striped rear end looks dangerous if not run of the mill, gross

Potato Bug

Potato Bug

Hi Rich,
We are happy to learn you have been introduced to a Potato Bug or Jerusalem Cricket, perhaps the single most iconic Southern California insect found in Los Angeles.  Potato Bugs are subterranean dwellers that are most visible after the weather cools and once the rains begin, because that is the time they come to the surface to search for mates or to escape flooded burrows.

This spider would build a web from a tree in my front yard to my daughters SUV in the drive way every night. The tree and SUV are approximately 15 to 20 feet apart. Yet every night it would rebuild its web. It took some doing but I was able to get it in the bag and take a photo of this big spider. Can you tell me what this is.

Orbweaver

Orbweaver

Dear ?,
This is a harmless Orbweaver in the family Araneidae.  We searched bugGuide to try to provide a species name for you, and this image on BugGuide of
Eriophora ravilla looks very similar, but it is apparently an uncommon color variation. She does not look happy in that bag.  We hope you released her after the photos were taken.  Orbweavers build a classic web and they await prey that becomes ensnared.  Though they gracefully maneuver within their webs, Orbweavers are rather clumsy on their own.  As you noticed, Orbweavers will build a web in the same location day after day unless they are disturbed, so we expect that relocation might be somewhat traumatic for them. We wish our maid wouldn’t sweep the webs on our front porch away, but as long as the spiders are unharmed, they can usually find a new place to spin.

Had seen this black and yellow spider hanging out in my marigold patch. Thought it was an Orchard Orbweaver at first until I saw my photos on my computer. Then a few days later I saw another smaller spider along with the black and yellow striped one (it wasn’t moving) At first I thought the bigger one was dead and the smaller one was in the process of liquifying its dinner. Then I thought maybe this was a male and they were mating. The next day I checked on the same web and the two were still there and I took the second picture. I also took a video when I thought they might be copulating. It was most interesting. Every 20-30 seconds and amber fluid drop would appear between them and then disappear as if reabsorbed or eaten. Can you tell what these spiders are and what they were up to?

Unknown Spider

Female Filmy Dome Spider

Dear D.K. Dodge,
We don’t recognize your spiders, but based on the tangled web, we are guessing they might be Cobweb Spiders in the family Theridiidae.  We searched through BugGuide, and your spiders bear a slight resemblance to this pair of
Phylloneta pictipes, however that appears to be a more southern species.  Perhaps one of our readers will be able to assist in this identification.

Unknown Mating Spiders

Mating Filmy Dome Spiders

Dan,
Because of the link and the update, I googled Neriene radiata and it is definitely the Filmy Dome Spider in my photos. What is even more confirming is that person’s observation that the courtship lasted for days.  I remember being very surprised when I kept seeing the pair for several days straight as I had assumed that all spider mating was a fairly quick proposition. Thanks for being such a great resource.  More to come from this bug-loving naturalist….

Hi D.K.,
Thanks so much for writing back to provide this identification update.  Your photos are stunning, and nearly identical to the image of mating Filmy Dome Spiders,
Neriene radiata, from BugGuide.

Hello Daniel,
I got a question about a spider again, and I only got one decent photo of it.
In term of size… it’s a relatively small spider about 1 to 1,5 cm toe to toe, and I found it hide behind a banana leave.
Hope that whatsthatbug could help identifying this guy 🙂

Unknown Spider from Indonesia

Spiny Theridiid Spider from Indonesia

Hi Mohamad,
We are sorry about the delay.  We have been very busy and we somehow overlooked your request.  We do not recognize your spider, but we will post the image and hopefully one of our readers will write in with an identification.

Karl provides a classification
Hi Daniel and Mohamad:
I believe this is a comb-footed spider (Theridiidae), also known as tangle-web or cobweb spiders. As far as I can tell, the black blade-like hairs at the end of the abdomen are characteristic of two genera, Chrysso and Meotipa. Christa l. Deeleman-Reinhold refers to them as spiny theridiids. Unfortunately, that is as far as I could get, as I could find no online photos or descriptions that pointed me to any particular genus or species. Nicky Bay Photography has posted numerous excellent images from Singapore that come close, most identified as Chrysso sp. or just Theridiidae. You can click here or here to check out two good examples. Project Noah also provides an image of a similar spider from India that it identifies as Chrysso sp. Regards.  Karl

Thanks so much for doing this intensive research Karl.

Wow thanks a lot Daniel and Karl for the clue…, first time seeing this spider and for me that is really interesting.
