Distribution of flying insects in relation to predacious web-spinning larvae of Neoditomyia farri (Diptera: Mycetophilidae) in a Jamaican cave

Larvae of predacious Neoditomyia farri Coher (Mycetophilidae: Keroplatinae) in Dromilly Cave in Trelawny, Jamaica, were restricted to the chamber where flying insects were most abundant. Here they occupied overhangs within 2 m of the floor. The distribution of flying insects was determined using adh...

Description
Summary:Larvae of predacious Neoditomyia farri Coher (Mycetophilidae: Keroplatinae) in Dromilly Cave in Trelawny, Jamaica, were restricted to the chamber where flying insects were most abundant. Here they occupied overhangs within 2 m of the floor. The distribution of flying insects was determined using adhesive traps. Total mean numbers throughout the cave varied between 953.0 and 10.5 insects per square meter of trap surface per hour. Scatopsidae predominated (up to 96%) where there were deep deposits of fresh bat guano and numerous roosting bats. Pholeomyia (Milichiidae) (0-2.4%) were similarly distributed but Phoridae (4-63%) were more evenly distributed throughout the cave. Minor components comprised Sciaridae (1%) followed by Scelionidae, Staphylinidae, Streblidae, Tineidae, Formicidae, and Mycetophilidae (all
