As a gardening and landscaping expert, I have had the opportunity to observe and study hoverflies in various settings. These fascinating insects play an important role in the garden ecosystem, as they are natural pollinators and also help control pest populations. One question that often comes up is how long hoverflies stay around.
Hoverflies, like many other insects, have a relatively short lifespan compared to mammals or birds. On average, adult hoverflies live for about 12 days. However, it is important to note that this is just an average, and the actual lifespan can vary depending on the species of hoverfly.
One species of hoverfly that has been found to live longer than average is the Hammerschmidtia ferruginea. These hoverflies have been observed living for up to 55 days. This is quite remarkable considering the relatively short lifespans of other hoverfly species.
The lifespan of hoverflies is influenced by various factors, including environmental conditions, availability of food sources, and predation. For example, hoverflies that have access to abundant nectar sources and suitable breeding sites are more likely to have a longer lifespan compared to those that face resource limitations.
In my personal experience, I have noticed that hoverflies tend to be more abundant during the warmer months of the year when flowers are in bloom. They are particularly attracted to flowers with open, shallow blooms that provide easy access to nectar. Hoverflies are often seen hovering in mid-air near flowers before landing to feed, hence their name.
During their short lifespan, hoverflies go through a complete metamorphosis, starting as eggs that are laid on plants. After hatching, they develop into larvae, commonly known as “rat-tailed maggots,” which live in water or damp soil and feed on decaying organic matter. The larvae then pupate before emerging as adult hoverflies.
Hoverflies are known for their distinctive appearance, with many species mimicking bees or wasps as a form of protective mimicry. This helps them deter potential predators, as they are often mistaken for stinging insects. However, hoverflies are harmless to humans and do not possess stingers.
In addition to their role as pollinators, hoverflies are also beneficial in the garden as natural predators of aphids and other small insects. The larvae of hoverflies are voracious eaters and can consume large numbers of aphids, which are common garden pests. This natural pest control can help reduce the need for chemical insecticides in the garden.
To attract hoverflies to your garden, it is important to provide a diverse range of flowering plants that provide nectar throughout the growing season. Some good choices include marigolds, zinnias, cosmos, and alyssum. Creating a habitat with diverse plant species and avoiding the use of chemical pesticides will help support a healthy hoverfly population.
The lifespan of hoverflies can vary depending on the species, with an average lifespan of around 12 days for most adult hoverflies. However, some species, such as the Hammerschmidtia ferruginea, have been found to live much longer, up to 55 days. Creating a garden environment that provides ample food sources and suitable breeding sites can help attract and support hoverflies, which in turn contribute to the overall health and balance of the garden ecosystem.
