They've begun to pupate.

Here are the 2nd and 3rd instar larvae. They develop the dark pattern and wider heads when they reach 3rd instar.

Here are some 1st instar larvae. They have done quite well feeding on frozen/thawed bloodworms.

Here some oothecae that they have produced. There is a bit of floating vegetation stuck to the silk "buoy."

Thanks for that suggestion! I think I will put together something like this. I may PM you with some questions as I go about it. Here are a few photos of a couple of my adults. I used to have two pairs, but now I am down to 1:2, male:female.

Hello All, I am currently raising about 30 Hydrophilus triangularis larvae in a communal setup. Two of my adult females produced oothecae back in July. I tried raising those larvae in individual setups but they all died, with only a couple making it to 2nd instar. I think this may have been due...

My name is Daniel and I currently keep a small group of Hydrophilus triangularis. I would be interested in hearing from anyone else who keeps this species or other aquatic species and I hope to learn a lot from this group! Cheers
