Looks similar to a butterfly we have in the US, Cabbage White (Pieris rapae).

A beautiful capture. It’s always so special to see a brimstone.

@rhoing They actually are not at all like the cabbage white (large white) but in flight the pale yellow female can be mistaken for the LW. There are none of the dark patches on the wings. Also the shape of the wings is very different and if a Brimstone settles and you don't see where it landed you'll have difficulty finding it. j

@susiemc @koalagardens Always a welcome sight, the bright yellow male flitting by in a hurry. The female can leave you asking yourself if she's a Brimstone, Large White, Small White, Orange Tip, Green Veined White if she's at a distance. j
