Predation can lead to the evolution of defensive devices in prey animals. Genitalia, which are used for mating between males and females, have rarely been considered to function as an important ...
When a female mason wasp feels threatened, she jabs her stinger at an attacker, injecting it with a potent venom so she can make her escape. Male wasps lack this defense, because stingers evolved from ...

Each of fifteen triplets of three male Polistes fuscatus (each triplet consisting of two brothers and an unrelated male) was placed into a cardboard box and each observed over a period of two days for ...
Males of a species of parasitic wasp can identify potential mates from chemicals they give off, even before the females have emerged from within their host fly. Jewel wasps (Nasonia vitripennis) are ...
