A striking Neon cuckoo bee, Thyreus nitidulus (Hymenoptera - Apidae) photographed in Chiangmai, Thailand.
These beauties with glittering metallic blue and black bands are cleptoparasitic in the nest of the Blue-banded bee Amegilla sp.
Neon Cuckoo Bee female does not make its own nest. It lays egg in the nest of Blue-banded bee. Female places an egg in a partially completed brood cell. After the Blue-banded bee finishes provision and seals the brood cell, the cuckoo bee egg hatches into larvae and feeds on the provisions stored by Blue-banded bee .
