Different-coloured antennae

Post by Toby Ludlow »

Has anyone come across this before: a butterfly with different-coloured antennae?

This butterfly has two different-coloured antennae: the left antennal club is a dull-orange colour, whilst the right antennal club is bright yellow. This is not a trick of the lighting.

It's not unheard of, here's an Essex Skipper with one slightly paler antennae tip.

I think the colour comes from scales/modified hairs similar to those that cover the wings and body so it's perhaps not such a strange occurance.
Some addictions are good for the soul!

Hybrid perhaps between Essex and Small Skipper?
