Pieris napi
A fairly-common butterfly of damp grassland and woodland rides, it tends to avoid dry, open habitats such as chalk downland. It is also a regular garden visitor but is generally out-numbered by Small Whites and Large Whites. There is a suggestion that climate change may adversely affect Green-veined Whites in Southern England. We shall see.
The first adults usually emerge in early April (but sometimes March, or even February) and peak in mid-May. A second, more numerous brood of adults emerge in July and August.
This species is well-distributed over all parts of the county, but the Sussex Weald is its stronghold. For an early spring record, one location that is worth a visit in April is the North Stoke amphitheatre at TQ035106.
