tadpoles are vulnerable to aquatic parasites such as planarians and Girardia sp. which can penetrate the gel capsule and eat the eggs. Another groups of midges that parasitize S. sila are Corethrella spp., which have a broad acoustic template allowing them to follow the mating calls of a variety of frog species, including those of S. sila. Their broad acoustic template also allows them to overcome the difficulty of host detection and localization and facilitate their shift between hosts, increasing their survival rate. The increased survival rate of the parasite increases the threat to the host S. sila.
