Dufour's gland

Dufour's gland is an abdominal gland of certain insects, part of the anatomy of the ovipositor or sting apparatus in female members of Apocrita. The diversification of Hymenoptera took place in the Cretaceous and the gland may have developed at about this time (200 million years ago) as it is present in all three groups of Apocrita, the wasps, bees and ants.
