Gelastocorids, or toad bugs, are so called because of their warty texture. They are cosmopolitan in distribution and are diverse in Australia.

Australian Gelastocorids occupy a number of habitats but are most common around areas that are muddy or sandy. The rough texture of their body, head and wings helps them blend into the substrate, where they hunt prey. Gelastocorids are presumed to be very broad in their prey selection and in the lab have been fed on a variety of insects including earwigs and termites.


Nerthra , a genus of the subfamily Nerthrinae, is the only genus recognised from Australia and contains about 28 described species distributed through all states and territories.

  • Gelastocoridae (Heteroptera)

  • Nerthra sp.
