In these tissues, the larvae develop into third stage larvae L3. The L3 migrates to the head of the fly, and is released in or near the eye of a new host mammal when the fly feeds. Once in the eye, eyelid, tear glands, or tear ducts of the mammalian host, the L3 larvae develop through the L4 larval stage and into adults in about Personal eyes Worms Germany month. The seasonal timing of L1 and L4 larvae in the lacrymal tear secretions of naturally infested dogs in Italy was found to coincide with the activity of the fly vectors.
