10 migrant dragonflies at Carlton Marshes
Towards the end of June our Carlton Marshes Nature Reserve has seen the influx of multiple vagrant emperor dragonflies.
These long-distance migrants originate from arid areas in North Africa and take advantage of southerly winds from the Sahara. These dragonflies don't appear every year and were last seen at Carlton 4 years ago.
More than 10 individuals are present currently and have been observed ovipositing (egg laying) where, unlike our native emperors, the male clasps the back of the head of the female while she lays her eggs both underwater and in damp, muddy holes. Their larvae grow very quickly, and the next generation of adults could emerge in Sept/Oct and continue their migration to pastures new.
