Entomology (Study of Bugs)/Feeding Brown Prionid



My children caught a very impressive brown prionid beetle, and they'd very much like to keep it for a while. What should we feed it?



Hi, Jacob:

The adult beetles in the Prioninae subfamily (family Cerambycidae) generally *don't* feed, or if so then it is on fermenting sap oozing from wounds in deciduous trees (in the eastern U.S.) or coniferous trees (western U.S.).  The adult beetles do not live long, so bear that in mind.  They emerge to find a mate (males) and mate and lay eggs (females).

Have a wonderful holiday weekend!

I answer insect and spider identification questions ONLY. Attach images if possible. No "what bit me?", "what do I feed this bug in captivity?", or science fair project questions please. NO TECHNICAL QUESTIONS ABOUT INSECT PHYSIOLOGY.
