Tiny blue tags wasp


Just when I thought there would be no more arthropods until springtime this tiny blue-tagged wasp starting working over the bark of a large eucalyptus. About 5mm long.


Suburban park on Eucalyptus bark.


Just noticed rear legs and femurs with an 'arching' shape... reminiscent of some bees - Chalcidoidea... ? Antennae seem to have elbows !!?

I guess it makes sense in at least a couple of ways. - carnivorous species are primarily opportunists and choose weakened creatures in preference to doing hard or dangerous work - also maybe they have the energy or metabolisms to push on into colder conditions when many vegos have slowed right down. It might not be 'outliving' exactly but more a population levels thing ie. carni numbers go up after more vegos become available. A bit like the way the numbers of spiders grew weeks after the insects had their good days last summer. I was really impressed with the energy of this little guy. I suppose he might have just been panicking that there was nothing much to eat.

Nice wasp. Here's a theory for you Mr. Bee. Carnivorous invertebrates outlive the vegetarian ones. My thought was prompted by this probable hibernator. Mantids live for several years. What do you think?
