I spotted one of these in May, whilst I was trying (and failing) to get photos of Delias nigrina, though I wasn't able to get close enough to see which particular species of blue I'd seen. I returned to the site during my lunch break as often as I could, until I was finally able to get some photos.
The butterfly I photographed was a male. I could see his blue colour as he flew, but when he landed he kept his wings closed.

I found a female in the Royal Botanic Gardens the following November. She was fluttering around a wisteria, and I thought she was a female Candalides absimilis, as there were several of them around. But when she landed underneath the leaf of a nearby plant, I saw she was this species instead. I was only able to get one photo, as she was rather timid, and it's a bit dim because she was in a shady spot.
