Help with ID, possible Metallic Wood Boring Beetle in Brazil
First off, great website! I am writing to congratulate and say that I have posted a video a while ago of a strange big beetle found on my parents house in Ribeirao Preto, Sao Paulo, Brazil. Attached are some stills of the beetle, some of them are on flickr as well. I had no idea if the insect was a cockroach or a beetle and on the comments for that video I was pointed to your website, where I could find some similar beetles photos, I am suspecting it was something similar to this other 2
Your beetle is indeed one of the Metallic Wood Boring Beetles in the family Buprestidae. We believe it may be Euchroma gigantea but we might be wrong. Perhaps one of our readers knows for sure.
You are correct in your species ID of the giant buprestid. I’ve never seen a live one, that must really be something!
Edibility update: big buprestid
Hope things are good with you two. The big wood borer is eaten in both the larval and adult stages. Here’s a source and pertinent text. http://www.food-insects.com/book7_31/Chapter%2007%20Colombia.htm Dufour (1987 ) reported E. gigantea among the foods of the Tukanoans. The Tukanoan name for it is boopica . This, plus other coleopterans used were all woodboring; the larvae were preferred although adults were occasionally eaten as well. The dry weight of the adult beetle was found to be 3.0g. Best,
