But like many who came before them, the researchers found no hordes of aestivating mosquitoes.

Terrestrial molluscs lie dormant in the winter in cold and temperate latitudes and their tropical allies aestivate in districts where conditions enforce the habit.

In such cases the insect must aestivate rather than hibernate.

In summer we had no fear of this creature, as it buries itself in the soil and aestivates during the hot, dry season, and comes forth in wet weather.

The land molluscs of the district are the only animals which aestivate; they are found in clusters, Bulimi and Helices, concealed in hollow trees, the mouths of their shells closed by a film of mucus.
