About 10mm long. First seen on a hyacinth orchid flower. After being photographed on my hand it flew to a nearby grass seed head (last photo). I assume it is a small longicorn beetle.
These have been in large numbers on our 2 zucchini plants since they were quite small, mostly apparently feeding on the flowers, and not affecting productivity much, if at all. Just in the last few days they've been joined by a bunch of other small beetles.
Wasps nesting in a Staghorn fern.
