The Common Blue (Polyommatus icarus) is a small butterfly widespread over much of the palaearctic. Recently it was discovered in Mirabel (off-island northern suburb of Montréal) Canada by amateur entomologist Ara Sarafian.

While the male has bright blue uppersides, the female is primarily brown, with a highly variable amount of blue.


It's filth, I tell you! The male passes sperm packets to the female, which she stores in her ovipositor to fertilize her eggs.

The female in the middle on the woodblock has just laid her eggs. The slug-like caterpillar of the Blues is already looking for food and crawls over the block.
