The group is working currently on very diverse organisms, including not only insect species but also other organisms, like plants and spiders with which they interact closely. In most cases, our research is motivated, at least in part, by our curiosity and our interest in natural history of organisms. This page reflects this interest.
Wolf spider (Pardosa sp)
Wood cricket (Nemobius sylvestris)
A windblown hair cricket ...
If one walks in the woods around Tours in spring and summer, one sees plenty of wood
crickets and wolf spiders. They both live in the leaf litter. Spiders exert a huge
selection pressure on its prey. Crickets show exceptional abilities in escaping to
predator attacks through the use of air-

The apple leafminer is developing within leaf tissues inside a mine. This species
has been studied for a while in our group and we have now an understanding of different
facets of its ecology: population ecology (density dependence effects and parasitism),
sensory ecology (vibratory signals involved in the prey -

Among the organisms we study, the spider crab is probably the ‘sexiest’: both its
This wood cricket also allows us to establish a bridge between century old natural history and futuristic bionics.

Some do not make waves, others do...
Whirligig beetles are amazing creatures and strong contenders for the first ‘sexiest’
place. They are living at the air-

The EducInsecte project
Created and led by Wilfried Kaiser, Jonathan Voise and Jérémy Defrize.
The EducInsect project is to inform people of what kind of work is being conducted in our lab. It does so in a simple and educational way. The background objective is to teach people stories about the fascinating world of insects.
The project consists in preparing entomological boxes containing photos of the insect
in its natural environment, information on its ecology and behaviour and the true
insect, dried and pinned on. Both insects studied in our lab and insects you can
find in our region are exposed. The project is exposed during the open-
