Rare in Cheshire and absent from Lancashire. This species stronghold is Hatchmere where it was first recorded in 1983 after an absence of 30 years. Sightings have come from marl pits around Tiverton, Tarporley and Huxley during the 1980s and from Churton in 1988. The latter remains the only other regular Cheshire site for this species in recent years.
Found in well-vegetated lakes, ponds, canals and ditches, rarely in slow-flowing waters although can be found in well-vegetated dykes.
Main flight period May – June, eggs are laid in stems and leaves of aquatic plants such as pondweeds and water-lilies but also floating remains of rushes and common reed. Nymphs hatching after a month with most larvae probably mature after one year.
A very scarce and localised species within the UK. Appears susceptible to dredging of ditches and agricultural intensification or conversion of grazing marsh to arable land.
Behaves similarly to Azure Damselfly as prepared to fly over open water in bright sunshine although often spends much of its time perched in waterside vegetation. Identification best confirmed by photography. Worth being on alert nearby the two current known extant sites as this species can easily be over-looked among hundreds of other Blue Damselflies.
