Common NameSwamp Bluet
Genus/SpeciesCoenagrion lyelli (Tillyard, 1913)
Abundance &
Rare throughout its range from near Brisbane around to the Grampians but perhaps a little more common in Tasmania.
HabitatAlthough it apparently inhabits a wide range of still and sluggish water I have only found it at dams and swamps with thick aquatic vegetation.
DescriptionThis is a medium sized damselfly with mature males significantly a vibrant blue with black. Although I haven't seen many females they tend to be a paler blue. I feature to hep identification is the pattern behind the eyes featuring two pale triangles joined by a narrow line.
Behaviour &
Like many similarly sized damsels these mostly perch on vegetation to around one metre from the water surface and do not spend significant time in flight.
Similar SpeciesSomewhat similar to other blue damsels. For example, Pseudagrion microcephalum has a similar pattern behind the eyes but the markings on the tail are unique.
