Ammophila sabulosa with lunch packet

Post by Troels »

In the summer 2016 I happened to get a series of pictures of this funny creature, the big Sand Wasp. But now I have taken the time to sort and edit the pictures.

Image
The wasp digs a deep hole in the sand with a nest chamber. Then it looks for a big larva which is paralyzed with a poison that does not kill the larva. The victim is carried to the nest hole.

Image
Then the larva is pulled down into the nest chamber where an egg is placed on the larva. The wasp larva then eats the moth larva. Since it is not dead it will stay fresh.

A big larva offers sufficient food for the wasp larva to grow up and pupate in the chamber. If only smaller larvae are available two or more are collected.

Image
The hole is filled and covered with sand and a single bigger stone.

More pictures from the event and a more elaborate explanation can be viewed on the great photo site of the canadian photographer Robert Berdan , where I am guest photographer.

These three pictures can be seen in full size only at my Flickr site

Excellent sequence (much better to see the whole set at Berdan's site)

Great sequence. First pic illustrates some formidable power in those jaws too! Can't help feeling a bit sorry for the victims though. What a way to go :shock:
