From CAB ABSTRACTS database, I found: TI: Experiments on predation and substratum choice by larvae of the muscid fly, Limnophora riparia. AU: Wotton-RS; Merritt-RW SO: Holarctic-Ecology. 1988, 11: 2, 151-159 TI: The life history and behavior of Limnophora riparia (Diptera: Muscidae), a predator of larval black flies. AU: Merritt-RW; Wotton-RS SO: Journal-of-the-North-American-Benthological-Society. 1988, 7: 1, 1-12 TI: Addition to the revision of the genus Atractodes (Hymenoptera: Ichneumonidae) of the western Palearctic Region I. AU: Jussila-R SO: Contributions-of-the-American-Entomological-Institute. 1983, 20: 201-204 TI: An association between a muscid, an ichneumonid and a simuliid recorded from a reservoir outfall in southern England. AU: Bass-JAB; Cooling-DA SO: Entomologist's-Gazette. 1983, 34: 2, 125-127 These might be good places to start for Limnophora riparia. Some of these authors presumably subscribe to this list. For Liancalus, more generally, see below.... TI: Redescription of Liancalus zhenzhuristi Negrobov (Diptera: Dolichopodidae) from Japan, with description of immature stages and biological notes.
