Methods

Ponds across North East Scotland were visited between May and August in each year, by between 1-4 surveyors per visit. At each site, the land immediately adjacent to ponds (within 2-5 m) was surveyed for all damselfly species. Damselfly surveys consisted of walking at a gentle pace around the pond, for a recorded period of time ranging from 15 minutes to 1 hour, depending on site density for each species. All adult damselflies encountered were captured by butterfly net and retained throughout the survey period. After the timed collection period had elapsed, damselflies were ID'd to species and were sexed before being released on site. Density data was calculated as the number of damselflies divided by the product of survey time in minutes and the number of surveyors, separatley for male and female damselflies. Total abundance was calculated as the sum of male & female abundances.
