Insects found in birds’ nests from Argentina: Anumbius annumbi (Vieillot, 1817) (Aves: Furnariidae) Author Turienzo, Paola Author Iorio, Osvaldo Di text Zootaxa 2008 1871 1 55 journal article 48988 10.5281/zenodo.183966 531f77bf-5599-45cf-8024-aec7cf4c96c3 1175-5326 183966 Dermestidae The South American fauna of Dermestidae , especially Trogoderma , is largely unstudied because several old type specimens need to be located and identified for revision. Only a few species can be identified with confidence because of their distinctive features. Five larval morphospecies found in the nests of A. annumbi provided identification of different adults as follows: Long black larvae [sp. 1] = Trogoderma sp. 1 Flat orange larvae [sp. 2] = Trogoderma sp. 2 Brown hairy larvae [sp. 3] = Trogoderma sp. 3 [black adults] Large orange larvae [sp. 4] = Trogoderma pectinicornis Reitter, 1881 Long orange larvae [sp. 5] = Trogoderma sp. 5 These larvae feed on dead insects found inside nests. The dead insect species used as food were present as hibernants and died inside ( Table 2 ). In addition, other insect remains were present (see section III). Adults of Trogoderma can be distinguished from other Dermestidae genera by the presence of a median ocellus, and the segment I of tarsus III being longer than segment II ( Kingsolver 1987 ).
