Two Sorts of Ladybird

Today's 30 Days Wild is a nice opportunity to talk about ladybirds.

I found two species on my walk today, dodging the heavy showers that interrupted the sunny afternoon.

One was a native 7 spot ladybird, the most commonly seen native species in my part of the world. The second is a non-native harlequin, in this variation a paler orange colour with more numerous spots and a white triangle on the head. You also get eye-catching black variants with two large red spots.

The natives emerge first in spring, but as the summer goes on, the harlequins become more numerous, out-competing the native species for food, and eating their eggs and young.

It's rather too late to stop this invader from Asia, however.

  1. Vetch - or Birds' Foot Trefoil - I think in your photographs Si. I have it all over my front lawn this year and have never seen it there before. When we were children we called it Lady's Slippers or Lady's Fingers. I love it.
    As for yellow ladybirds - I have never seen one up here - are we too far North or am I just not looking hard enough?

  2. Perhaps the harlequins haven't made it up further North yet?
