Ecology Summary - Jupiaba iasy

Language:

Main Ref.	Netto-Ferreira, A.L., A.M. Zanata, J.L.O. Birindelli and L.M. Sousa, 2009
Remarks	Specimens of Jupiaba iasy were collected in sandy beaches in both rio Teles Pires and rio Jamanxim. Analysis of the stomach contents of four c&s paratypes (32.0–40.1 mm SL) revealed presence of mayfly nymphs, chironomid larvae, pupae and adults, caddis fly larvae, a staphylinid beetle, unidentified insect fragments, fish tissue, scales, sediment, and unidentified plant fragments. The higher amount of autochthonous benthic insects eaten by the examined specimens, suggests that Jupiaba iasy explores the bottom and has a tendency towards insectivory, although it also feed on plants.
