Researchers at Kobe University in Japan published a paper on Dec. 19 in the journal Current Biology where they found that male mason wasps use their genitals to stab predators such as frogs in ...

Fending off an attacker by swordplay with two genital spines turns out to be a moderately useful form of self-defense for male wasps, an unusual study shows. A mason wasp’s rear spikes may be ...

In the past, genitals have rarely been considered to have any anti-predator defence functions but researchers at Kobe University have made the bizarre discovery that mason wasps use these sharp ...

Two thin, retractable "genital spines" lie on either side of the male mason wasp's (Anterhynchium gibbifrons) phallus. Some wasps use such spines to hold females in place during mating ...

Describing your junk as a weapon is a pretty undesirable trait in humans, but for wasps, it could be a lifesaving adaptation. New research has found that the mason wasp got pretty creative when it ...

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 ...

As a result, male wasps are considered harmless. This is why it was so shocking when one of the lead researchers was seemingly stung by a male mason wasp (Anterhynchium gibbifrons). How could this be?

Female bees and wasps use modified ovipositors, formerly used in egg laying, to sting their attackers, including people. Now, a study in Current Biology on December 19 shows that male mason wasps ...

Female wasps have a venomous sting to discourage predators, but males lack this protection. Now, researchers have discovered that male mason wasps have an alternative defence strategy ...

Researcher Misaki Tsujii from Kobe University in Japan found this out firsthand while studying the life history of the mason wasp (Anterhynchium gibbifrons) when she got stung. While stings are ...
