Mock Orange (Murraya paniculata) is popular with nectar-feeding insects when it bursts into flower, as ours did recently.
Some years ago I noted that I had seen yellow paper wasps, Ropalidia romandi, in my garden but hadn’t seen the nest, presumably also in my garden, which they were coming from. Its location could have been vital information, saving me from a nasty confrontation, so I kept on looking – with no success at all.
I finally spotted it very recently, above the roof-line of our high-set house in a paperbark tree (please visit this page if you want to call it a bottlebrush – it’s both) and overhanging the neighbours’ fence. A clear view of it was only possible from one or two locations even when I knew it was there, so I don’t feel too chagrined at missing it for so long.
This is little more than a footnote to my January 2016 post about the insect life to be found in bookshelves in the tropics: I noticed a can of insect spray tucked discreetly in the corner of a bookshelf and moved it to reveal …
The nest-builder is one of our common mud-dauber wasps (potter wasps), probably a Sceliphron like this one.
There is always something new to see on a walk around the park and on our stroll with Wildlife Queensland folk last Sunday I noticed this beautiful little egg dangling from a shrub. Its silken thread suggested to me that it might be a spider’s egg-case (I knew the little dewdrop spiders create similarly rigid egg-cases and suspend them from a thread like this), and everyone knows that caterpillars make cocoons from silk and some suspend them from plants.
A little creative internet searching revealed, however, that it was neither of the above but the cocoon of a small parasitic wasp in the family Campopleginae, one of the 1500+ subfamilies of the Ichneumonidae.
That level of identification is as close as I will get, but this link will take you to a splendid international collection of photos of the adult wasps. Sometimes I love the internet!
Everyone knows about bookworms, even if all they know is the name, but bookworms are not the only small wildlife found in bookshelves, particularly in the tropics, as a recent bout of librarianship associated with repainting a couple of rooms has shown me.
Wasp nests like these were by far the most common sign of insect life in our bookshelves. Female mud-dauber wasps (Sceliphron sp.) construct a cell, lay an egg inside and provision it with food for their larvae then, if they can, repeat the sequence nearby. A string of cells like this will have been constructed in a short time (days or weeks) by a single wasp and, if all went according to plan, her children would have emerged and followed suit.
