Duke of Burgundy Fritillary (Hamearis lucina)
© Nick Greatorex-Davies
The Duke of Burgundy is a rare butterfly occurring in small discrete colonies in scrubby calcareous grassland and recent woodland clearings where its larval foodplants, either Primrose (Primula vulgaris) or Cowslip (P. veris), grow in reasonable abundance in sheltered but open, sunny conditions. The butterfly has undergone a major decline in Britain especially in woodlands. (For further details on this species see http://www.butterfly-conservation.org/).
Family: Nymphalidae

Back to the topLog collated index plot
This chart shows the index of abundance (LCI = Log Collated Index) over time. It shows fluctuations in populations from year to year, and is scaled so that the average index over the whole series is equal to 2 (horizontal line). For greater detail about how this index is derived, click on the green question mark above.
Trend description:
This species appears to be rather more stable than many species showing generally relatively small fluctuations in numbers from year to year. However at several BMS sites the butterfly has declined to extinction. The data show no significant trend, but data are from only a small number of transects.
Distribution...
This map shows the distribution between 1995 and 1999. Data is derived from the Butterflies for the New Millenium dataset via the NBN Gateway (www.searchnbn.net).

This chart shows the average number of butterflies seen on transects between Arpil and October. The black line gives average counts over the full BMS series (1976 to date) and the red line gives the average for the last year.

This map shows symbols for the mean abundance at transect sites, with the size of symbol reflecting the level of abundance. Means are over all years.
Coverage
In total, Duke of Burgundy Fritillary has been recorded from 179 transects in the Butterfly Monitoring Scheme. Of these, annual indices of abundance have been calculated from 144 sites, with an average index of 5 individuals per site.
For 90 of these sites, Duke of Burgundy Fritillary has been recorded well enough to calculate annual indices of abundance in 6 or more years, allowing trends to be calculated.
In 2006, 269 individuals were recorded from 19 sites, producing annual indices at 20 of these.
This map shows the trend in abundance at particular transect sites. Trends (increasing, declining or stable) are assessed at sites where the species has more than five years of annual index data. Click on the green question mark next to the species name above for more details on how trends are calculated.
