A bizarre and unsettling wildlife phenomenon has been reported across parts of the United States, with sightings of so-called 'zombie squirrels' exhibiting strange, tentacle-like growths on their faces.
What's Causing the Zombie Squirrel Outbreak?
Wildlife experts suggest these disturbing facial growths are actually caused by a common squirrel botfly (Cuterebra emasculator), whose larvae burrow under the skin of rodents. The 'tentacles' are breathing tubes created by the parasites as they develop beneath the host's skin.
Where Have These Squirrels Been Spotted?
Reports have come from multiple states including:
- New Jersey
- Ohio
- Michigan
- Pennsylvania
While alarming in appearance, experts confirm these infected squirrels pose no direct threat to humans.
Why Are They Called 'Zombie Squirrels'?
The nickname stems from:
- The grotesque facial deformities
- Reports of affected squirrels behaving erratically
- The parasite's ability to control host behavior to some degree
Dr. Sarah Whitman, a wildlife veterinarian, explains: 'The larvae secrete substances that alter the squirrel's behavior, making them less cautious as the parasites near maturity.'
Is This a New Phenomenon?
While botfly infections in squirrels aren't new, the current outbreak appears more widespread than usual. Climate change may be contributing to increased parasite populations in some regions.
Wildlife officials recommend against handling any squirrels showing these symptoms, though they emphasize the condition is part of a natural (if disturbing) ecological cycle.
