Feeding trials of Leptagrion andromache and prey species

We quantified the consumption rate for one damselfly larvae predator and many of its prey. The top predator Leptagrion andromache (Zygoptera: Odonata, dry mass = 3.31 mg, se = 2.45, n = 29) was fed several densities of each prey. The prey were chosen because they were the most abundant prey in bromeliads. All prey are aquatic insect larvae. We chose Culex sp 1 (Culicidae: Diptera, density range = 1- 50, mean dry mass = 0.17 mg, se = 0.04, n = 25), Culex sp 2 (Culicidae: Diptera, 1-20, 0.09 mg, 0.02, 14), Forcipomyia (Ceratopogonidae: Diptera, 1-60, 0.07 mg, 0.01, 5), Dero superterrenus (Naididae: Haplotaxida, 1-60, 0.12 mg, 0.01, 2), Psychodidae (Psychodidae: Diptera, 1-30, 0.22 mg, 0.11, 18), Scirtes sp 1 (Scirtidae: Coleoptera, 1-30, 0.33 mg, 0.12, 13), Scirtes sp 2 (Scirtidae: Coleoptera, 1-6, 0.43 mg, 0.27, 65), and Trentepohlia (Tipulidae: Diptera, 1-7, 0.29 mg, 0.19, 43).
