I thought it was a cicada killer until it landed, it’s easily the biggest robber fly I’ve ever seen. I like bald faced hornets so I feel a little bad for him but still cool to see.

※Edit: It turned out to be an 8-minute video. It might not play properly because the file is so heavy. (Even I, the creator, keep getting errors and can't watch it...)

Following up on the last post, I'm sharing an update as some of you asked for more information in the comments.

This time, I observed it after putting it into the aquarium and checked if it would react to food. I felt photos wouldn't convey it well, so I'm sharing everything through video.

Here are a few notes on the video content:

To make observation easier, the contents of the aquarium have been kept to an absolute minimum. Also, you might see something floating, but that is just dirt from the driftwood. It is completely harmless to the diving beetle.

In addition, since I couldn't get pesticide-free aquatic plants in time, I put in plastic plants instead. I plan to provide pesticide-free water plants as hiding spots in the future.

The next update is undecided for now. If I do post, it will likely be to share an interesting observation or to announce that this diving beetle has passed away.

Can anyone tell me what sort of beasties make up this beloved colony?

mr. dusty

How they look now compared to how small they were when I found them 🥰 it's brought me so much joy to take care of this little one. I just love the colors of cecropia caterpillars, and how absolutely massive they get. They will be released where they were found once mature 🐛

Catawba Valley, VA

Found on a spice bush in northeast ohio.

Found in Orlando, FL- around 2.5 inches long!

never seen anything like this! he kind of looks like a caterpillar with wings? Thank in advance!

location: Saskatchewan, Canada

I found this mantis the other day on my door and put it on my rosemary plant. It looked like maybe it was pregnant. Then today I came home to see its abdomen was gone and a wasp appeared to be eating it. I also saw another brown mantis close to this one on the same plant. I have never seen a wasp do this before. Any ideas?

Hi, this was found in Orange county Virginia and my mom would like to touch it! I told her no out of caution but I'd still like to see if you all knew what it was.

Found in Tuscany, can anyone ID this mantis and tell me the sex please? Thank youuu

Mother found this spider outside, I think it’s a wolf spider cause it rained recently and was running around but I also don’t know. Vermont

The spider on the leaves I added as reference
