Insect winter ecology describes the overwinter survival strategies of insects, which are in many respects more similar to those of plants than to many other animals, such as mammals and birds. Unlike those animals, which can generate their own heat internally ( endothermic ), insects must rely on external sources to provide their heat ...

In some cases "winter" is characterized not ...

Rhinophorinae is a subfamily of flies (Diptera), commonly known as Woodlouse Flies, [3] found in all zoogeographic regions except Oceania, but mainly in the Palaearctic and Afrotropical regions.
