Annex G- White Admiral A small increase in numbers seen and range was noted for this species in 2015. Records received identified that the butterfly was seen in 61 tetrads, 6 more than in 2014. The map below identifies the distribution in the county in 2015.
Figure 5. Distribution map for White Admiral 2015. The first White Admiral was recorded on 28th June and the flight season appeared to naturally finish at the end of August. A late record on 13 September at Hurst Fen, Mildenhall Woods was the only record received which was indicative of a second generation. The highest count was of 14 butterflies seen at Pakenham Woods on 9 July, although, several other low double figure counts were made. Despite being a butterfly of mature deciduous woodlands several records and photos received for this species concerned individuals seen in gardens and parks. This reinforces the fact that it is a strong flyer prone to wandering and seeking out new territories. Despite the species appearing to be stable in the county, albeit, in low numbers the national position is very different. The UKBMS 10 year trends indicate a 43% fall in abundance and the 2014/2015 year comparison shows a -19% fall.
