Common cattle grub

<em>Hypoderma lineatum</em>, commonly known as the common cattle grub, is a parasitic fly species with documented occurrences in Japan, Norway, Sweden, and the United States. It typically inhabited terrestrial and freshwater environments, often associated with cattle and other large ungulates on which its larvae develop as subcutaneous parasites. The species is classified as Extinct on the IUCN Red List, indicating that it is no longer known to exist in the wild. Common cattle grub belongs to the genus <em>Hypoderma</em> within the family Oestridae. Adult flies do not feed and are short-lived, while larvae burrow under the skin of host animals, causing a condition known as hypodermosis or warble fly infestation. The decline and extinction of this species has been linked to widespread and highly effective veterinary treatment programs targeting warble fly larvae in cattle, which drastically reduced host populations and ultimately eliminated the species. Biological traits such as average lifespan, body length, and mass of this species remain poorly documented in the scientific literature.
