Lycaena helloides

Purplish Copper

The male and female Purplish Copper are distinctly different from each other, only the male, which is small and darker than the female, showing the purplish sheen when viewed at certain angles. The butterfly illustrated is a female. I have found the egg and caterpillar on Rumex crispus, but it is difficult to find, and I expect it can also be found on other species of Polygonaceae.
