You can watch the wonderful flights of the Banded Demoiselle above slow-moving streams, south of the Humber, as they emerge from their two-year larval existence beneath the water, to their couple of weeks life as flying adults. The males, with dark
petrol blue bodies and bands across their wings, emerge and fight other males for territories, (beautiful to watch) before mating with the bronze-green coloured females. They do a dancing mating flight, before clasping the female behind her head and flying to a leaf with her ‘in tandem’ (see photos), where she will coil her body round to the ‘wheel’ position for mating. After a few minutes they separate and the female flies off to find a plant just below the water’s surface on which to lay. The male defends her until she has safely deposited their eggs. Conditions: Cloudier and a little cooler but still dry. Temperature: Max 22 Min 13C.
