Coleoptera: Family Meloidae
Description: Antenna, venter and tarsus are black. The head and pronotum are reddish, with a black spot on the pronotum likes a heart. Elytra are reddish with black bottom and a black spot on the middle.
Biology : The Meloidae that have been referred to as parasitic have relationships with their hosts that are not a true parasitism, where individual larvae consume the body contents of the host and complete development there on. In Meloidae, the host egg is consumed, and feeding thereafter is on the food mass stored in the cell by the parent bee.
Nemognathinae is a subfamily which parasite the cells of various bees of the family Andrenidae. In Nemognatha chrysomelina, the eggs are found in small batches on the blossoms of Echinops spinosus, and hatching coincides in time with the complete opening of these blossoms and gives the maximum opportunity for the young larvae to attach to Anthidium and other bees that frequent the blossoms of this plant.
