Hypoderma bovis is a species of fly belonging to the family Oestridae, commonly known as the cattle grub. This insect is primarily found in North America and Europe, where it lays its eggs on the skin of cattle. The larvae develop under the skin, causing various health issues for the host animal. The life cycle of Hypoderma bovis includes several stages: egg, larva, pupa, and adult fly. The larvae can cause damage to the host's tissues and may lead to secondary infections. Effective management strategies are essential to control infestations and minimize the impact on cattle health and productivity.
