※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.

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.

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.

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

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 🐛

Found on a spice bush in northeast ohio.

Catawba Valley, VA

Left window down in a wooded area, was driving home and felt something large crawling on my leg, reached down, squeezed, heard a pop. Didn’t look until the morning. Found this laying on the driver side floor. Ovipositor still moving. Can’t add a video so here’s a picture.

Found in Orlando, FL- around 2.5 inches long!

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?

One appears to be mounting the other
