Brown Lacewing Micromus variegatus

The larvae of Lacewings eat all kinds of harmful insects that damage plants, such as plant lice and leaf lice. They are cultivated and set free in green houses to consume the leaf lice on cucumbers and tomatoes, in order to use less chemicals. Green Lacewings are very well known, but there are also brown ones.

Mind you: it is not absolutely certain tha both the adult and the larva are of the species Micromus variegatus. There are several other brown lacewings and it is virtually impossible to identify the species from just pictures.
