The “skeeter eater” is a common nickname for a flying insect often mistaken for a giant mosquito. This popular moniker suggests the creature preys on mosquitoes, leading to misconceptions about its true nature. This article clarifies the insect’s identity, behaviors, and ecological role.
Identifying the Crane Fly
The insect commonly called a “skeeter eater” is a crane fly. These insects belong to the order Diptera. They are characterized by their notably long, slender legs that easily detach from their bodies, a relatively delicate body, and a single pair of wings.
Crane flies typically range in wingspan from about 1.0 to 6.5 cm, though some larger species can reach up to 11 cm. Their elongated appearance, especially their stilt-like legs, often leads people to confuse them with oversized mosquitoes. Despite this visual similarity, crane flies possess different mouthparts and wing characteristics that distinguish them from mosquitoes.
Debunking the Mosquito Myth
Contrary to their common nickname, adult crane flies do not consume mosquitoes. They lack the necessary mouthparts for preying on other insects, possessing snout-like mouths rather than the piercing, tube-like mouths found in mosquitoes. This myth likely stems from their mosquito-like appearance and the “skeeter eater” name.
These insects are harmless to humans, as they do not bite, sting, or transmit diseases. While their large size and tendency to fly erratically, sometimes bumping into objects, might seem alarming, they are merely seeking an exit from indoor spaces.
Crane Fly Diet and Life Cycle
The diet of a crane fly varies significantly between its larval and adult stages. Adult crane flies often consume very little, with some species not feeding at all during their short lifespan of a few days to two weeks. If they do feed, they typically ingest nectar from flowers, decaying plant matter, or simply water.
In contrast, the larval stage, known as “leatherjackets,” actively feeds. These larvae live in moist environments such as damp soil, decaying wood, or aquatic habitats. Their diet primarily consists of decaying organic matter, plant roots, or algae, making them important decomposers. The crane fly life cycle progresses through egg, larva, pupa, and adult stages. The larval stage often endures for an extended period before pupating and emerging as adults.
Ecological Importance and Human Impact
Crane flies play a role in ecosystems, primarily through their larval stage. As decomposers, leatherjackets contribute to nutrient cycling by breaking down organic material in the soil and other damp environments. This process enriches the soil and supports plant growth.
Adult crane flies also serve as a food source for various animals, including birds, bats, and other insects. While crane fly larvae can sometimes feed on grass roots, significant lawn damage is rare. Crane flies are not considered agricultural pests, and their presence is generally benign.
