New beetles

I have collected some new beetles and would like to know if I might be able to breed them.

the beetles are

  • Phileurus valgus
  • Euetheola humilis
  • Pasimachus punctulatus
  • Leptinotarsa decemlineata
  • Euphoria kernii
 
Thank you, I am particularly interested in breeding P. valgus and E. kernii. I have already observed E. kernii mating, but I don't know what they will oviposit in.

 
It's highly unlikely you'll be able to breed the Pasimachus, only two people I know of have gotten eggs from their females that ended up hatching, and each person only got a single egg from their females. Out of those two people, only one was able to rear their larva to adulthood.

That being said, you can keep them on a coconut fiber/sand mix and see if you have any luck, if you do get an egg, be sure to separate to it's own deli cup. The larvae are predatory like the adults, but lack basic hunting skills, so they'll need soft, pre-killed prey. Just feed it often, remove old food, and you should be good. Once it gets big enough, put it in an enclosure with compressed sandy substrate and hope for the best.

Euphoria basically just need LOTS of crushed leaf litter, they should oviposit in that, the larvae will eat it, and it should make up the bulk of their substrate, (along with small amounts of rotten wood and/or compost).

So breeding and raising Pasimachus is similar to Scarites?

What kind of leaves? I have Elms, Honey Locust and Cottonwoods. Which would be better? Every other leaf-eating invert I have kept has liked the Honey Locust.

Pretty much, breeding them is similar to breeding a wide variety of Carabids, however LOTS of people have kept Pasimachus, they are one of the most commonly kept Carabids in captivity, and very few have reported any reproductive activity besides mating. I myself got an egg from one of my species a couple months ago, it never hatched though.

I'd think Elm or Cottonwood would be the best choices, Honey locust may work as well. Just make sure the leaves are highly decomposed and easily crushed!
