Broad-bodied Chaser

The Broad-bodied Chaser is a very distinctive Dragonfly that is found in several locations across Europe, Central Asia, and the Middle East. They are typically found around areas of still water, and fly from April until September, though are most common from May to June.

Both the male and female Chasers have very flat, broad abdomens (hence the name). Both sexes have yellows spots running down the length of the abdomen, but the primary color differs. Males develop a pale blue pruinescence, while females have abdomens that are golden brown.

Males of the species are very territorial, and will fight other males that enter their airspace. If a female enters the territory, the male will often approach and grapple them, mating in mid-flight. The coupling is very brief, and afterwards the female will search for a suitable place to lay her eggs. She deposits them by flying over water with submerged vegetation, and dipping her abdomen in. It will take around a month for the eggs to hatch, and the young Dragonflies can live underwater as larvae for up to two years. Once they become adults, they often spend some times away from the water.
