Figure 1
Variation in maximum annual counts between odd- (filled columns) and even- (open columns) year cohorts of the southern damselfly Coenagrion mercuriale along a transect at AYL in Figure 2. Note that the counts are comparable from 1994 when the transect was standardised along a specific route. All counts were made during warm, relatively calm days between 1200 and 1400 hours during which there was sunshine for at least 60% of the time (data provided by L Kerry).
