    Hello, I caught a large dytiscidae larvae in a local pond. I have been feed it crickets for about a week and it had a hearty appetite. It stopped feeding today so I think It might be ready to pupate.

    Has anyone successfully kept this kind of beetle? Do I need to do anything for it other than giving it some soil to borrow into?

    exactly.give it soil/moss very moist,it will crawl out of the water and bury itself there,it will make its own pupal cell there,acouple of weeks it will remain there without being disturbed,it will emerge from there,good luck i used to raise them all the time.very interesting to observe.

    An update, the beetle has successfully pupated. Can the adult be kept Like the larvae or will it fly around my house?

    nice, you can keep it in an aquarium,the water doesn't have to be that deep,alot of floating plants,and regular plants on the bottom,they do like to climb out and dry out aliitle,and then back into the water where they are most of the time,i would cover the tank,yeah they will fly around if they can get out. very easy to keep,and longlived. good luck.

    Ill house it in the tank I had the larvae in, 10 gallon aquarium planted with weeds I pulled from the lake. Ill add a piece of driftwood so it has something to crawl out on.

    How long lived we talking? 6 months?

    I have a juvenile lethocerus in there at the moment, probably have to seperate them.

    Make sure you keep its cage covered or could fly out, they're excellent flyers. Make sure you remove the lethocerus one will kill the other.
