Potter wasp emerging from window frame. Photo by Lucinda KingEvery year, we hear about lots of weird and wonderful places that birds have decided to nest, but birds aren't the only creatures that pick what can seem odd places to build a home.

Last week, while staring out of my window at work (again!) I realised that some sort of wasp was paying particular interest in part of the window frame - going in and out of a hole carrying something.

It was fascinating stuff to watch, and only when the wasp misjudged the hole and spilt what she was carrying on the window sill could I see that it was in fact a little clump of sand.

And how do I know it was a female? Well, after several failed attempts to get a photo, I finally managed to snap a few, and track her down as the nattily named Ancistrocerus parietum, or (easier to say and remember!) as being part of the potter wasp family.

It turns out that it is the female who searches for the nest site, builds the nest and brings in food for her young - namely tasty larvae that she seals in with her eggs so that her young have something to nibble on as they grow!

And true to this description, this week, she has been carrying green caterpillars - as big as her body - into the nest.

I've got a new respect for these creatures, and it just goes to show that sometimes you don't have to go far to see things that are new and amazing.

I'd love to know if any of you have found nests in unusual places. Please leave me a comment below.

  • We have bumble bees in our bird box this year and they are busy up to dark I have tried taking photos for my magazine but they wont stay still!

  • Our Buff Tailed Bumble Bees usurped the bat box and are busy looking after our fruit and veg!

  • We have bees nesting in the railway tracks on the reserve here at Strumpshaw Fen!  I don't know what type they are, but they are in and out constantly - it must be a bit scary in there when a train goes over the top of their nest!

  • I had a normal wasps nest two years ago on my allotment, they had made it under my artichokes. All my digging and going to and from the shed and they never minded. Not even when I had to dig a patch not far from their nest the guards came out to see what was going on, and apart from keeping a close watch on me they left me alone.

    That year I had the best veggies out of all the plots not one pest was on my food, they ate the lot. :-)

    yey go the wasps.  I luv em

  • Thanks Woodsi - it most certainly is cool!

    And like your bees, 'my' wasp doesn't seem bothered by my presence, even when I get close to the entrance hole, trying to get a peek into the nest!
