The short answer is: blue dragonflies are not rare at all. In fact, the most commonly recognized “blue dragonfly” – the Blue Dasher (Pachydiplax longipennis) – is incredibly widespread and abundant across North America, extending into the Bahamas. It’s crucial to understand that the term “blue dragonfly” can be somewhat misleading because not all dragonflies that appear blue are the same species. However, when we talk about the classic blue dragonfly, we are most often referring to the male Blue Dasher, which exhibits that characteristic chalky blue coloration. This particular species is quite common, making sightings of a blue dragonfly a fairly regular occurrence, particularly during the summer months near bodies of still water.
Why the Confusion About Rarity?
The perception of rarity might stem from a few different factors. Firstly, people might confuse the Blue Dasher with other dragonfly species that display some blue hues. While the Blue Dasher is very common, other dragonfly species with blue elements may indeed be rarer. Secondly, not all Blue Dashers are blue. Females and young males have a different coloration, typically a brownish body with yellow and black stripes, which can lead to the mistaken belief that seeing the blue morph is a rare event when, in fact, many blue dashers might have been simply overlooked as another variation. Thirdly, the specific habitat of the Blue Dasher is around still water bodies, including wetlands, lakes, and ponds. If someone does not frequent such areas, their opportunities to see these dragonflies will be limited. Finally, individual variation in colour intensity can occur. While most mature males are chalky blue, some may be lighter or darker, leading some observers to think that they have spotted a rare version. So, the commonness of the Blue Dasher and other blue species can easily be overlooked due to these nuances.
Understanding the Blue Dasher
The Blue Dasher is part of the skimmer family, known for their diverse colors, patterns, and habits. The males, particularly, are identifiable by their chalky blue body, a dark abdomen tip, a white face, and turquoise eyes. This vibrant coloration is a stark contrast to the females and young males. The Blue Dasher has a wide distribution, stretching from southern Canada down to Mexico, and also includes the Bahamas, Cuba, and Belize, although they are notably absent from the Rocky Mountains and the Dakotas. These dragonflies are sometimes known as the Swift Long-winged Skimmer or the Blue Pirate, further underscoring their common presence in various habitats. The “long wings,” indicated by the species name longipennis, aren’t actually longer than related species, but are believed to appear so in females due to their shorter abdomens.
Life Cycle and Behaviour
The adult Blue Dasher typically lives for a short period, usually just a few weeks up to a maximum of around two months. These carnivorous insects are active hunters and play a vital role in controlling populations of other insects, particularly small flies. This behaviour is helpful in mosquito control as they are mosquito-devouring machines . Like all dragonflies, Blue Dashers begin life as aquatic nymphs, spending significantly more time underwater than as adults. The nymphs feed and grow before undergoing metamorphosis, emerging as winged adults to complete their life cycle.
