Size is in the pictures.

Basically can be used with any species smaller than a dynastes hercules hercules.

Recommend species like dynastes grantii, dynastes tityus, taiwan rhino beetle, japanese rhino beetle, allomyrina pfeifferi, xylotrupes, strategus aloeus AND MUCH MORE.

I do sell a bigger version of this one fit for dynastes hercules(few supply here on my website).

Ultra clear lets you see the larvae grow and transform into a pupa, and eventually a beetle without disturbing it. Thin sidewalls make it a great place for rhino species to pupate.
