|Lesser Swallow Prominence (Pheosia gnoma)|
|View from above of the Lesser.|
So, here are the facts:
- The Lesser Swallow Prominent is actually more common in England, Scotland and Wales but it is less so in Ireland.
- The Swallow Prominent can range from 40mm - 55mm while the Lesser Swallow Prominent is (of course) Lesser and ranges from 45mm - 50mm.
|Swallow Prominence (Pheosia tremula)|
- The Lesser Larvae feed, very specifically, on birch. They then overwinter underground in their cocoon.
- The Swallow Prominent larvae eat Poplar and Willow and also overwinter underground, the same as the Lesser.
- They both eat, as Adults, Nectar from most plants.
- They are found in Woodlands, Meadows (where they will find most of their food from), Heathlands, Parks and Gardens.
|Hairy head close up|
- They were first recorded in 1854 although they will have been around way before that time.
- The way to tell the difference between the two of them is by looking at the white wedge toward the top of their wings. In the Lesser Swallow Prominent it is a chunkier, shorter wedge.
- Both species may well have two broods. They are generally on the wing between May and June and then also again in August.
