N. Stringer, V. Benno Meyer-Rochow] 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 <0.2%). Numbers of flying insects decreased logarithmically with increasing height. In areas of high insect abundance, fewer insects flew near the walls than in the center of the chamber. Estimates of numbers of insects caught in N. farri webs indicated that food availability more than any other factor determines the distribution of these larvae. © 1996 Entomological Society of America Ecology and Population Biology nationallicence Neoditomyia farri nationallicence Diptera nationallicence cave ecology nationallicence Mycetophilidae nationallicence fungus gnats nationallicence Stringer Ian A.
