A solitary mud-daubing wasp, Brachymenes dyscherus (Hymenoptera: Vespidae) fron Brazil with evidence of a life-cyde polyphenism

Nests ( n=60 ) of a solitary mud-daubing wasp, Brachymenes dyscherus were conected at Fazenda Santa Carlota, Cajuru, Sao Paulo, Brazil ín 1995 and 1996 . The multi-celled mud nests were constructed on the interior walls of abandoned houses in dry and shaded places. Nests were composed of 1 to 4 laye...
