Description:

Fritillary feeding on bramble flowers.I did not get a look at the under wings.I chose Small Pearl Bordered rather than Pearl Bordered because of the distribution maps in J A Thomas's Guide to Butterflies. I've been watching this patch of grass for three years and this is my twentieth species of butterfly and the first Fritillary.

It's always very rewarding

It is not a good idea to base

It is not a good idea to base IDs on distribution maps unless these are up to date. If you look at the map for PBF, it is in your area. I don't know about phenology down there, but in N Scotland SPBF is not out yet - it is later than PBF. There people who can do them from a character on the top of the wing, but I can never remember what it is - perhaps someone who knows can enlighten us.

One way of telling the PBF

One way of telling the PBF and SPBF apart using their upper wings is to look at the second cell up from the hind edge of the forewing.

The squarish spot in this cell is roughly one third of the distance from the chevron near the edge of the wing to the bar near the inner end of the cell. This is the case in the photos here.

In the PBF the spot is closer to half way between the other two marks.

In general it's easier to distinguish them by examining their undersides, if you get the opportunity.

Small pearl

I've been on the UK Butterflies web site and looked at the comparison of the spot differences on the upper wing and they are the pattern of the Small Pearl-Bordered Fritillary. The distribution maps on the site also indicate SPBF.
