The prolonged arrested development during diapause may reduce the flight capacity of the overwintering generation.
The relative frequencies of the genotypes that invest in different overwintering strategies are highly correlated with the abundance of the primary host.
At least in 1998, the exit of butterflies from overwintering sites was relatively sudden and coincided with the first spring rainfall event.
Following the oviposition period, cages containing several thousand overwintering eggs of each population were placed in a field insectary.
The bud may be part of the stem of an overwintering structure such as a bulb or tuber.
However, our data indicated that this characterization might only be true for the overwintering generation because the succeeding generations explore the whole tree canopy.
However, each of these species can also be grown as a shortseason cover crop or, if climate allows, as an overwintering cover crop.
In the same area, the offspring generation of overwintering females was collected as eggs and firstinstar larvae within 12 breeding sites.
