This erstwhile squatter, who thinks she can build residences for all her offspring just wherever she pleases, still remains at large – but the evidence is mounting. Further sleuthing has turned up more mud structures. These dubious looking pods were found in the shed attached to a garden chair cushion.
Needing said cushion necessitated their removal – they wern’t stuck too tight and I took the liberty of breaking through the crisp skin – only to find it packed with little spiders, some still alive. So, my fiendish quarry is not averse to incarcerating her victims alive – what a horror bag!
The wasp will have stung these spiders to paralyse them before dragging them off into their Cell of Doom. And then the wasp will have deposited a single egg, and sealed up the nest pod. The larva then has enough handy food to sustain its development into adulthood.
As is typical with most things, when you actually WANT to find wasps, there are none to be seen. I did track down this possibility, but it seems that she has a different MO.
I would dearly like to capture Madame Mud Dauber red-handed, in flagrante delicto – the pursuit continues.
