Fiddler beetle

Thank you LarsKorb

Thanks ramyavajapeyam and Francis. most scarabs as grubs eat wood or roots and pupate without a cocoon on the ground or under bark. you seldom see them until they're adult.

Thanks for your comments Ashish, Karen and Scott.

This is a cetonid scarab. These can launch in a fraction of a second by opening the elytra a fraction and wings slide out the side. They're gone!!!

Thank you. I found 10 cocoons. Seven emerged. I opened one to find a live fully formed beetle and left two to emerge in their own good time.

Thanks for your comment. This emerged this morning after watching the cocoons for about two months! I have found about six cocoons and two have emerged. See in "related spottings" another person has found one that is green instead of yellow. They are very variable.
