Have you noticed an unusual amount of crane flies this year? These long-legged insects, also known as “mosquito hawks,” are typically seen in the fall months, but this year they seem to be more prevalent than ever before. So, what’s causing this sudden increase in crane flies?
The Weather
One possible explanation for the surge in crane flies is the weather. This year, there have been several factors that could have contributed to their abundance. For instance, the warmer-than-average temperatures and increased rainfall create the perfect conditions for crane flies to thrive. Additionally, the wetter weather could have also caused an increase in the numbers of the crane fly larvae, as they require moist soil to survive.
The Life Cycle of a Crane Fly
In order to fully understand such a phenomenon as a surge in crane flies, it’s important to have some understanding of their biology. Crane flies have a lifecycle that consists of four stages: egg, larvae, pupa, and adult. The eggs are laid in soil or water, and the larvae, or “leatherjackets,” are often found in moist soil, feeding on roots and grass. Once they become adults, crane flies emerge in the fall and live for only a few days. So, if there are more larvae due to wetter weather conditions, there are likely to be more adult crane flies as well.
The Role of Predators
While crane flies may be a nuisance to humans, they play a critical role in the ecosystem as a source of food for other animals. Many predatory birds and insects, such as dragonflies and bats, rely on crane flies as part of their diet. However, an increase in crane flies could lead to an imbalance in the ecosystem or an increase in predator populations in the long run.
Conclusion
So, why are there so many crane flies this year? It’s likely due to a combination of environmental factors such as weather conditions, which have provided the perfect breeding environment for crane fly larvae, and the resulting increase in their numbers. While crane flies may not be everyone’s favorite insect, they are an important part of the ecosystem and serve as a food source for many other creatures. As such, their increase in number this year may have far-reaching consequences.
