Tropical wasps attack intruders with unfamiliar faces

4 febrero 2015

The scientists went to the remote tropical forests of South East Asia to study this tiny wasp species. Each nest contains a family of related individuals and hundreds of nests can be clustered together to form a kind of city. Close proximity to so many other families means each colony faces persistent landing attempts by intruders from the neighborhood, and these might steal resources or theoretically lay cuckoo eggs.
