Pemphredon Flavistigma
''Pemphredon'' is a genus of digger wasps (Spheciformes) from the family Crabronidae. The genus is common in the Holarctic, 12 species are represented in Europe. Several species are considered beneficial because of their specialization in aphids. Features The ''Pemphredon'' species are often small and black coloured and have some similarity with ants. They have a short, furrowed abdominal stem, two submarginal cells in the forewing and a well developed head, especially behind the compound eyes. The species identification is difficult. Based on the course of the submarginal veins the genus is divided into three species groups, which some authors also regard as subgenera. These are the ''lugubris'', ''morio'' and ''lethifer'' groups. In the former, the outer vein of the second submarginal cell meets the marginal cell noticeably below the middle and the second returning vein ends in the second submarginal cell, which is usually longer than wide. In the ''morio'' group, the out ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

He published his first important work in 1796 (), and was eventually employed by the . His foresighted work on arthropod systematics and taxonomy gained him respect and accolades, including being asked to write the volume on arthropods for George Cuvier's monumental work, , the only part not by Cuvier himself. Latreille was considered the foremost entomologist of his time, and was described by one of his pupils as "the prince of entomologists".
