| Biology: |
Inhabit more slow flowing areas of the headwater habitats (Ref. 34011). Found usually in ravines and isolated elevated pools. An adult and several juveniles are usually encountered in submerged leaf litter. Adults may take cover under floating leaves and are excellent jumpers, which may explain their presence in isolated elevated pools (Ref. 56613). Feed mainly on terrestrial insects and occasionally on aquatic invertebrates (Ref. 56613). |
