Here's my waterscorpion getting dinner on a stick. Originally had a much better video where it reacted faster and more voraciously, but sadly that footage was lost while trying to trim it down to postable size.Attached File  trim.F04B263A-075E-4735-92D8-47E9A96E0E14.MOV   3.6MB   53 downloads

Just a chunk of frozen cocktail shrimp.

Admittedly, it's probably not the best thing to feed hemipterans, since there's no skin or shell to hold it in when it becomes soup.

That is awesome though! I should try that with the various insects I keep. I currently have a Cybister fimbriolatus and a Lethocerus griseus that I would like to keep in good shape to observe. Perhaps target feeding with impaled food is in order!

I had never thought about actually keeping one. Why not though? Very cool. Now I am going to have to read up on waterscorpions, as I really know very little about them.

I've kept Ranatra and large diving beetles (Cybister or Dystiscus? not sure) feeding them mostly mealworms and occasional other insects. Large diving beetles I find more often while playing tennis at night than when out hunting for fish & bugs (my principal reason for playing tennis). I've never seen a live Lethocerus wild - only the small common Belostoma.

I find that lethocerus are hard to find by netting in water- it's better to use a strong UV light ( such as a bug zapper with the wires leading to the electrocuting grid cut) shined against a big white sheet in field next a body of water. You can catch tons of lethocerus, as well as lots of other neat bugs, aquatic or otherwise. Also a great way to collect live food. Lethocerus are pretty boring, though. You get to watch them viciously attack a food item once every few weeks, then they just sit there ignoring food the rest of the time.

And now, here's my lethocerus eating a dead cockroach:Attached File  trim.F211A089-D6B9-40F2-9C9B-EAAB4DFBA546.MOV   586.08KB   8 downloads
For some reason, i could post the waterscorpion video even though it was much longer than this, but it wouldn't let me post this until I made it really short.

Neat videos. You would be better off uploading your videos to a site like youtube and then linking or embedding them here. That way you wouldn't have any file size limit issues.
