Black Saddlebags (Tramea lacerata) lives in freshwater areas across North America. It feeds on insects and larvae. Its conservation status is Least Concern.
Fascinating facts about the Black Saddlebags
- The black saddlebags displays distinctive black blotches at the base of each wing, a pattern that makes it look as if tiny saddlebags are hanging from its sides and gives the species its common name. It is a relatively large dragonfly, measuring about 5 centimetres in length. This skimmer dragonfly is found throughout North America, favouring stagnant water bodies such as ponds and ditches where it can be easily observed.
- Like all dragonflies, Tramea lacerata mates in the characteristic "wheel" position, after which the female stores all the sperm she will need for fertilising her eggs. If she later mates again, the new male uses a brush-like structure on his specially adapted penis to strip the previous male's sperm from her body.
- During egg laying, the male releases the female so she can drop onto the water surface and deposit her eggs before she climbs back into his claspers. The eggs hatch into larvae that immediately begin hunting any smaller organisms they can capture, showing a strongly carnivorous diet. Both the aquatic larvae and the flying adults are efficient mosquito predators, making them valuable allies in wet habitats where mosquito numbers can become problematic.
- Both the aquatic larvae and the flying adults of the black saddlebags are voracious mosquito hunters, keeping numbers low around ponds and ditches. The newly-hatched larvae immediately begin feeding on any smaller creature they can capture, showing a strong carnivorous preference. Adult males often gather in large swarms, which increases the chances of encountering mosquito prey.
- Male black saddlebags frequently assemble in conspicuous swarms. These gatherings occur near stagnant water bodies such as ponds and ditches, where they can readily access breeding sites.
