Mystery Insect

A few questions have come into the office on whatent.knodel.4.crane fly these large mosquito-like insects are! Fortunately, it is not a large mosquito, it is a crane fly (Family Tupulidae), and is non-biting and harmless. They are common during spring and attracted to lights and often found on screens outside of houses. Crane flies also rest on foliage of landscape plants around the house. Some larvae are semiaquatic and others live in dry soils of pastures and lawns. They help break down and process organic materials and increase microbial activity. Adults and larvae are important as prey for birds, fishes, amphibians, other insects, and mammals.
