Mud Wasps and Wonder Nests!

Mud wasps (mud daubers) are seen coming inside the house through the windows and then getting out after a while. They fetch mud pellets to build nests on wall corners, ledges or the ceiling.

They also prefer 'artificial man made nests' - like the screw holes seen on the speakers, or the power plug points! They simply lay eggs in them and seal with mud.

I have seen colorful whorls of paper like nesting material inserted one over the other like plastic cups, inside power plug points. The nesting material used here are the petals from the flowers of Bougainvillaea! Inside the central tube-like part of this 'flower' the wasp lays eggs and seal.When I break open these wasp nests, I often find semiconscious spiders or caterpillars moving their parts now and then.

Cuckoo wasp is different and it behaves like cuckoo in placing its eggs in other mud wasps' nests to get its larvae fed and brought up by the host wasp!
Again and again I could post more and more about these wonder wasps that drive you away from their nests, and but do not sting you at all! You can share with me your own experiences with wasps here.

Wasp Nest with 'Live Feeds' encountered

This week I found a freshly formed nest of Mud wasp in the corner of a window. It was made of red soil. On breaking open it from the corner I found inside the cells three big wriggling larvae of the wasp brown, and yellow in colors and also --- 61 smaller larvae of some other insect! The smaller larvae were bright greenish in color, and lay paralyzed! They have been put inside the nest by the female of ‘Mud dauber’ (Black and yellow Mud wasp), after stinging them. I had seen before only paralyzed spiders in such nests. Now with this nest I find larvae of other insects too. Probably availability factor makes difference in the type of such live foods, it seems.
Inside another older nest of the same type of wasp I found fifteen mature wasp larvae with the remnant pieces of the smaller larvae!

I was risking the stinging by the mother wasps while I broke open the nests. But later I read that they do not return to the nests after sealing the last cell with mud!

It is really a wonder behavior in these wonder wasps!
