This post supplements my previous post, about a trip to Ollera Creek.
A nest but not the right nest
While we were sitting in the shade enjoying a snack, we were visited by a number of small yellow and brown wasps which I immediately identified as Yellow Paper Wasps, Ropalidia romandi, and warned people about: they sting when threatened. Fortunately we were all mature enough not to react thoughtlessly when the wasps landed on exposed skin, apparently in search of moisture, and no-one was hurt; but we did look for their nest.
