What is a Wolf on a Squirrel? 
Occasionally, you may notice a small, white wolf on a squirrel. This might be an adult warble botfly, or it could be the larvae of a Cuterebra emasculator fly. These are both larvae of the bot fly Cutereba, which lays its eggs in areas where squirrels travel. After hatching, the larvae attach to the squirrel and burrow underneath its skin for three to four weeks. While it is not an actual predator, it does eat the squirrel’s fluids and feces.

Warble botfly
You may have noticed a warble botfly on your squirrel. This small, insect-like creature is a parasitic fly that feeds on the lymph fluid from your squirrel’s body. In the spring, the flies emerge as adults. However, they are rarely a problem for squirrels. In fact, warble infestations tend to occur only during early fall when squirrel hunting season opens. Most hunters will discard warble-infested squirrels.
The larvae of the warble botfly live in your squirrel’s oral passage for several days before they emerge from it as adult insects. Once mature, these insects can cause a variety of physiological effects to the host, including anemia and changes to the size of their organs and glands. However, despite these negative effects, these parasitic insects have no known effect on the population dynamics of their host.
Adult botflies are larger than the larvae and usually inhabit rodents, rabbits, and pigs. Adult botfly resemble a bumblebee, but differ from other bumblebees because of their size and hair structure. These insects are black and dark blue in color. The taxonomy of this parasite is unclear, and if you suspect that your squirrel is infected, take a photo of it and keep it safe.
Cuterebra emasculator Fitch
The Cuterebra emasculator, or skin bot fly, is an internal parasite of tree squirrels and chipmunks of the eastern United States. Asa Fitch described this new world critter in 1856. Since that time, it has become an important source of income for tree squirrels and chipmunks. While the name may seem a little strange, its name has stuck ever since.
Although the larvae of Cuterebra emasculator are natural rodent parasites, there is no control over these critters. Infested squirrels cannot spread the infection to other animals, and the infestation is unlikely to affect your home. The infective stage larvae remain under the squirrel’s hide until they are fully developed. Only the first instar of the Cuterebra emasculator fly is infectious.
This parasite feeds on dead cells, lymph fluid, and pus. It can spend three or four weeks feasting on its host, turning brown in the process. The larvae are not capable of reproduction, but they do interfere with the male’s reproductive cycle. Nevertheless, this hypothesis needs further testing to be tested. Currently, the Cuterebra emasculator parasite does not directly affect the reproductive function of the host.
Cutereba larvae
Stacy Wood in Talladega, Alabama, opened her sliding glass door to find a squirrel with barnacle-like growths. She took pictures of the squirrel and later learned that it was infested with bot flies. She was able to identify the bugs by their scientific name, Cutereba emasculator Fitch, which is actually a species of fly. The larvae feed on the squirrel’s testicles.
The first instar of a Cutereba fly is whitish and covered with black spines. The larvae sway back and forth as they search for a host. The next stage of the larva’s journey is to attach to an open wound or nasal passage. The journey takes about a week. Then, the larvae molt into an adult fly and migrate to a new host.
The cutereba emasculator is a natural parasite of rodents. There are no treatments or control methods for this infestation. However, it can affect squirrel hunting seasons. Hunting seasons for squirrels are only allowed to start after the main Cutereba emasculator infestation period has ended. The infective stage of Cutereba larvae remains under the host’s hide until it has fully developed.
