The results also suggest the parasitoid has no mechanism of overwintering outside its hosts.
They observed distinctly higher abundances of overwintering adult staphylinids compared to carabids, similar to the present investigation.
The removal of semi-natural habitats due to the intensification of agricultural practice can lead to a reduction in overwintering sites.
Males are supposed to die before the overwintering period, and are not present in overwintering sites.
The prolonged arrested development during diapause may reduce the flight capacity of the overwintering generation.
In many cases, cold hardiness ensures successful diapause during overwintering, thereby enabling the insect to survive the cold winter months.
Most of the 105 clones, which were collected in both years, overwintered on winter hosts.
At least in 1998, the exit of butterflies from overwintering sites was relatively sudden and coincided with the first spring rainfall event.
