Coexistence, habitat associations and puparia description of three dipteran species of the family Carnidae.

摘要: Differentiation of niche by means resource partitioning facilitates coexistence species with similar requirements. Here we analyse the association between different habitats (i.e. nest types) and two Diptera poorly known Family Carnidae that coexist during their larval pupal stage in nests troglodytic bird species. We also describe for first time puparium Hemeromyia anthracina longirostris offer morphometric data puparia these Carnus hemapterus. Both smaller size occurrence well-developed spiracles allow easy discrimination C. The both is very only differ distance small spiracles. hemapterus coexisted boxes but former did not occur natural sandy cavities where, turn, was highly prevalent. prevalence its abundance higher type nest. This study shows clear associations dipteran specific types nests. Yet, some conditions are seemingly acceptable
