The better to pinch you with

There was no need to flip a rock to find this angry mother; she was waiting for prey (or my fingers, whichever came first) out in plain sight, on a rock Campbell River beach.

Giant seaside earwig, Anisolabis maritima

The females lay their eggs in cracks or burrows and stand guard over them. The sturdy pincers at the end of the abdomen can deliver a nasty pinch. When I got too close, this one raised them straight up towards me, in a threat gesture. (The males do not stand guard, but run when they notice us. Their pincers  are curved strongly inward, almost forming a circle.)

I kept my fingers well away.


Three more days until Rock Flipping Day!


  1. That's pretty threatening, and reinforces the warning you posted Re: rock-flipping day--to remember that some creatures don't take kindly to being revealed, even for the sake of science (or nature-admiring curiosity, which is often the same thing). Still, I can't wait to uncover some beasts around here...

  2. Interesting but kind of scary to find where maybe your toes might go. - Margy


I'm having to moderate all comments because Blogger seems to have a problem notifying me. Sorry about that. I will review them several times daily, though, until this issue is fixed.

Also, I have word verification on, because I found out that not only do I get spam without it, but it gets passed on to anyone commenting in that thread. Not cool!
