Andricus Quercusfrondosus
''Andricus'' is a genus of oak gall wasps in the family (biology), family Cynipidae. Life cycle As in all Hymenoptera, sex-determination system, sex-determination in species of the genus ''Andricus'' is governed by haplodiploidy: males develop from unfertilized eggs and are haploid, and females develop from fertilized eggs and are diploid. Many species in the genus alternate between an asexual reproduction, asexual generation and a sexual reproduction, sexual generation. Species The taxonomy of the genus ''Andricus'' is uncertain, with many of the approximately 375 species considered dubious. The following species are currently recognised in the genus ''Andricus'': * ''Andricus aciculatus'' Beutenmuller, 1909 * ''Andricus ahmeti'' Melika, Mutun & Dinç, 2014 * ''Andricus albicomus'' Weld, 1952 * ''Andricus albipes'' Hartig, 1840 * ''Andricus albobalani'' Weld, 1926 * ''Andricus alniensis'' Folliot, 1964 * ''Andricus amblycerus'' (Giraud, 1859) * ''Andricus amenti'' Giraud, 185 ...
