An amazing habit of Blabephorus pinguis

Blabephorus pinguis Fairmaire, 1898

(Subfamily Dynastinae, Family Scarabaeidae, Order Coleoptera)
The beetles found associated with the ground-wasp net. But we do not know
exactly what kind of relationship betweeen them. The beetle larvae likely get the
benefit from the wasps. Body form is reddish brown, short and strong concave
above, with short brownish-yellow hairs beneath. Male, head armed with a short,
strongly curved horn. Pronotum is broadly excavated at the middle; front tibia with
four teeth. Female, head armed with a short conical tubercle; pronotum with
a broad longitudinal furrow, narrower than that of the male. Length 28-32 mm.
Distribution: India, Myanmar, Sumatra, Vietnam, N. Thailand
(Wiang Pa Pao, Mae Taeng).
