A single individual feeding on the nectar of a blue-flowering exotic whose name I've forgotten. Possibly a male.

Hmm, our book shows images of both sexes, but I'm stumped as to what the differences are. They look pretty nearly identical. The plant is Oxypetalum coeruleum (used to be Tweedia caerulea), no common name that I'm aware of, although being such a striking plant you'd think someone would have come up with one.

Thanks Jackie. I remember the name Tweedia now. That's how I'd known it before. Is it an exotic?
Re the monarchs, my book's illustrations show a few more dots on the margin of the forewing in males but my phone pics aren't much to go by.

Yep, exotic, and fairly invasive, so if it is on your place or nearby road verge I'd be pulling it out.

This is a male - see the black patch of sex scales on the first vein out from the inner margin of the hindwing on photo 2.

Thanks Glenn. Now that you point them out I can see the marks on the wings in the pic and in the Braby illustrations.
