Common Awl Robberfly

<em>Neoitamus cyanurus</em>, commonly known as the Common Awl Robberfly, is a predatory dipteran insect in the family Asilidae. This species is classified as Least Concern on the IUCN Red List and is distributed across northern and western Europe, including Belgium, Denmark, Norway, and Sweden. Like all robber flies, the Common Awl Robberfly is an active aerial predator that captures other flying insects in mid-flight, using its strong legs and piercing mouthparts to subdue and consume prey. Adults typically frequent open and semi-open habitats such as forest clearings, heathlands, and sunny woodland edges where prey insects are abundant. The larvae are believed to develop in soil or decaying wood, where they feed on other invertebrate larvae. Adults are typically observed perching on bare ground or low vegetation, from which they launch short, rapid flights to intercept passing prey. Their robust build, bristly body, and forward-pointing beak are characteristic features of the Asilidae family. Biological traits of this species remain poorly documented in the scientific literature.
