On olive. Doesn't look the same as the iNat obs of A. oleae (Common olive beetle), with its red face (is that the face end?) and thin stripes, which makes this an uncommon olive beetle? :-D
Feeding pattern of grazing the leaf surface, also visible.
Are the larvae leafminers? I collected several leaf mines from this tree, but only one ever became something, and that was a trio of wasps. Don't know what the original larva was - beetle? lepi?
Doesn't look like the Common Olive Beetle, so it must be an uncommon olive beetle?
Only one photograph, so some force employed to get it through https://www.inaturalist.org/journal/beetledude/14682
Found in very large numbers 90+
trapped in a steel can of water with many other species of beetles.See this observation. https://www.inaturalist.org/observations/35892361#activity_comment_3732954
I think this is the beetle whos larva is used for poison arrows
