Thank you! New to me.
Thank you again, Tyler!!

The only somewhat similar one I had photographed was Ecyrus dasycerus, and I could see it was not a match.

Any idea what these Cerambycidae associated with oak trees would eat as adults? Maybe pollen, or do they munch on the oak tree itself? Some do quite well in captivity, but others are short-lived, and I'm wondering if I'm not providing the proper diet.

Also, do you recognise this guy?

Food source
I'd guess they'd feed on pollen from nearby flowers and maybe nibble on the oak leaves a bit. It probably varies a bit depending on the subfamily since I've never found lamiines (like Ecyrus) on flowers, but regularly find lots of species of cerambycines (like Styloxus) on flowers. Sap flows should attract both subfamilies.
