Most species within the Sycoracinae are thought to feed primarily on
reptiles and
amphibians, although direct behavioural observations are limited. For instance,
Sycorax silacea has been documented feeding on the European edible frog,
Pelophylax esculentus, and can serve as a vector for
filarial parasites. Similarly, the Ecuadorian species
Sycorax wampukrum has been observed preying upon
harlequin frogs (
Atelopus spp.). Larvae of European Sycoracinae develop in moist mosses along streams. The larval habitats of tropical genera are currently unknown. ==References==
