Common Cone-headed Grasshopper

<em>Acrida ungarica</em>, commonly known as the common cone-headed grasshopper, is a large grasshopper in the family Acrididae. This species is notable for its distinctively elongated, conical head that gives it a slender, streamlined appearance. It typically inhabits open grasslands, meadows, scrublands, and the margins of wetlands, where tall grasses provide both food and cover. <em>Acrida ungarica</em> is a phytophagous species that feeds primarily on grasses and other herbaceous plants. Its coloration varies from green to brownish-yellow, offering effective camouflage in its grassy habitat. The species is distributed across parts of Europe and western Asia. It is assessed as Least Concern on the IUCN Red List, with no major threats identified to its populations. Biological traits of this species remain poorly documented in the scientific literature.
