How to make artificial pupal chambers for beetles.

If it's your first time, you may be worried, but it won't be as difficult as you think.
You should check the insect condition before move it!
And if the size of the chamber you made is too small or too large, your beetle won't be able to make complete wings. Scoop the foam in a proper size.
Spring has come. In spring, I feel great because insects are getting more active :)
