Common Whitetail (Plathemis lydia) lives in freshwater habitats across North America. It feeds on insects and larvae. Its conservation status is Least Concern.
Fascinating facts about the Common Whitetail
- Male whitetails pack a punch: about 5 cm (2.0 in) long, their bodies are mostly flight muscle, giving them one of the highest flight-muscle ratios of any animal. This muscular edge gives them an advantage in aerial contests for territory, but the trade-off is a lean gut and low fat reserves, which may reduce longevity. This trade-off may influence which males achieve greater mating success.
- A single male will guard a stretch of water up to 30 m (100 ft) long, patrolling it like a tiny sky-sentinel. This narrow strip is the battlefield where rivals clash, and holding it boosts a male's chance to mate because females prefer the best egg-laying spots. The quality of the defended zone, not how long a male stays, predicts reproductive success, highlighting territory quality as the key currency in whitetail love wars.
- When females arrive to lay eggs, they turn down almost half of all courting attempts, up to 48.9%, by rejecting males. Yet this selectivity doesn't translate into higher reproductive success for any particular male trait; body mass, wing length, and first day of reproduction show no effect. The high rejection rate likely reflects a strategy to speed up mating and avoid predators, rather than a choosy preference for the fittest partner.
- Whitetail nymphs live underwater for most of their lives, enduring a staggering 99.9% mortality rate before emerging as adults that live only a few weeks.
- In California, adult whitetails are on the wing from April through September. Their presence across ponds, marshes, and slow rivers during this period makes them a natural pest control agent.
