==Description==

Cutaneous Habronemiasis is a hypersensitivity reaction to the larvae of the nematode species ''Habronema'' and ''Draschia''. The adult nematode lives in the stomach of the horse and produces eggs which are then passed in the faeces as larvae. The larvae are ingested by the house fly (''Musca domestica'') or stable fly (''Stomoxys calcitrans'') in their larval phase, and deposited on equine skin when they feed as adult flies.[Insecta|house flies or stable flies]]
