The "labour parasitism" of the spider wasp Anoplius viaticus

The spider wasp Anoplius viaticus displays an interesting breeding behaviour which partly differs from that of other spider wasp species. Relatively often (sometimes several times a year) I observe that a wolf spider which is captured, narcotized and left on a certain place by a female wasp is stolen by another female of Anoplius viaticus (see also the picture story "Hard work for a single egg").

Observations on the reed fly Lipara lucens

For a couple of years I have been studying the life of the reed fly Lipara lucens and its relationship in the habitat reed. You can find a complete photographic report regarding this topic on my site under picture stories called "An apartment in the reeds".
