As the summer months roll around, you may have noticed that your backyard is suddenly crawling with crane flies. These long-legged creatures can be an annoyance to many homeowners, but have you ever wondered why there seem to be so many of them? In this article, we will explore the reasons behind the abundance of crane flies in 2021 and why they are an important part of the ecosystem.
Life cycle of crane flies
To understand the reason for the sudden increase in crane fly population, we must first look at their life cycle. Crane flies lay their eggs in damp soil or decaying vegetation, which provides an ideal environment for their larva to live and grow. The larva feeds on organic matter and can take up to two years to mature. When the time comes, they transform into a pupa, which eventually hatches into an adult crane fly. With a lifespan ranging from a few days to a couple of weeks, crane flies spend most of their time seeking out mates and laying eggs before they die.
Reasons for the increase in crane flies
The increase in crane fly population can be attributed to several factors. Firstly, the weather conditions in 2021 have been favorable to the development of crane fly larva, particularly in areas with high humidity levels. The excessive rainfall and warmer temperatures created the perfect conditions for crane flies to lay their eggs. Secondly, the reduction in the use of pesticides has allowed the crane fly population to increase as their natural predators have been eliminated. Finally, the planting of large areas of grassland in urban areas has also contributed to the increase in crane fly populations as they provide a suitable habitat for the larva to mature.
The role of crane flies in the ecosystem
Although they can be considered a nuisance, crane flies play an important role in the ecosystem. During their larval stage, they help break down organic matter and recycle nutrients in the soil. They also provide a valuable source of food for other creatures, such as birds and small mammals, that are part of the food chain. Additionally, they can act as a pollinator for certain plant species as they seek nectar from flowers.
Methods to control crane flies
While it may be tempting to use pesticides to eliminate crane flies, these chemicals can have harmful effects on the environment and other wildlife. Instead, there are several natural methods that homeowners can use to control the crane fly population. One such method is to reduce damp areas in the garden by improving drainage or removing standing water. Using natural predators such as birds and insects can also help to control the population. Finally, mowing the lawn regularly can prevent crane flies from laying their eggs in the grass, as the eggs require damp soil for development.
Conclusion
In conclusion, the sudden abundance of crane flies in 2021 can be attributed to a combination of favorable weather conditions, reduction in pesticide use, and suitable habitats for the larva to mature. Although they may be an annoyance to homeowners, crane flies play an important role in the ecosystem and should not be indiscriminately eliminated. By using natural methods to control their population, we can ensure that they continue to play their part in maintaining the delicate balance of the environment.
