Green-veined White
Pieris napi
This record describes Pieris napi (species). Recorded family: Pieridae. Recorded order: Lepidoptera.
Identification and Appearance

It is often mistaken for its cousin, the Small White. The so-called green veins on the underside of the adults are, in fact, an illusion created by a subtle combination of yellow and black scales. The Green-veined White is a similar size to the Small White and whilst the green-yellow veining of the underwing is a clear diagnostic feature, the upper wings are very similar. However the black tip in the Green-veined White is usually less 'solid' and extends in blotches along the wing edge. This is a common butterfly of damp grassland and woodland rides but it also turns up in gardens. First-brood adults typically emerge in late April, peaking around the middle of May and gradually tailing off through June. The second brood, which is always stronger than the first brood, starts to emerge in early July. However, in good years, the second brood may emerge in late June and give rise to a third brood. The main larval foodplants are Charlock ( Sinapis arvensis ), Cuckooflower ( Cardamine pratensis ), Garlic Mustard ( Alliaria petiolata ), Hedge Mustard ( Sisymbrium officinale ), Large Bitter-cress ( Cardamine amara ), Water-cress ( Rorippa nasturtium-aquaticum ) and other cruciferous plants. This is one of the most widespread species found in the British Isles and can be found almost everywhere.

About Butterflies and Moths: the wider group
Order-level background for Lepidoptera, the group containing Pieris napi. Species-specific details appear above.
Group overview
Lepidoptera includes approximately 180,000 described species of butterflies and moths. Moths outnumber butterflies roughly 10:1. The monarch butterfly's eastern population has declined by more than 80% since the mid-1990s, and the western population by over 95% since the 1980s. The IUCN lists the migratory monarch as Vulnerable.
Ecological role of the group
Butterflies and moths are essential indicators of ecosystem health. As caterpillars, they are a primary food source for birds - a single nest of blue tit chicks requires ~10,000 caterpillars. Adult moths pollinate many night-blooming plants.
Economic and practical significance of the group
Lepidoptera are critical pollinators. In Europe, grassland butterfly species have declined by almost 50% since the early 1990s. In the UK, three-quarters of butterflies are in decline. In the U.S., five butterfly species have gone extinct since 1950, with 29 listed as endangered.
