Found in some spinach taken from the garden and photographed on the kitchen bench. About 3 mm long and iridescent dark blue-black. Possibly the same one as in Jackie's sighting 3407043.

Hi Jackie. Yes, a distinctive feature shared, I noticed, by some paropsisterna species. I looked through that genus on the ALA and there are a few similar ones but none that look exactly like it.

Happy to help, Jackie. Leaf beetles of the Paropsis group resemble ladybirds, although most are larger than ladybirds. A giveaway is in the antennae, which in ladybirds are short with a club on the end, whereas in leaf beetles they are longer and 'simple', i.e. without a club.

Thanks Kim. That's helpful. I'll remember to pay more attention to the antennae in future.
