What was it on?
If Encelia farinosa then Haplorhynchites planifrons

Hi Margarethe -
It was on Encelia frutescens. I don't know anything about Curculionidae, though wonder whether they're species-specific or stick with a genus, or group within a genus.
Plants in the frutescens clade have few or no benzopyrans or benzofurans, as opposed to the california clade (the latter includes E. farinosa). This difference may have a practical meaning to these weevils.
Thanks to both of you, Vassili and Margarethe!
I just looked at planifrons, looks rather similar. SBMNH lists only two spp. for CA: aeneus, and planifrons. It may well be planifrons, but I have no key to these.
I'll check with Jim Hogue, will take the specimen. All solved now, though I had forgotten my specimen at home.
