Lone Star Tick

Amblyomma americanum adults are well-known to feed on large mammals, especially bovines and white-tailed deer. It is an ectoparasite of a wide range of domestic mammals, e.g., cattle, horses, goats, sheep, cats and dogs, and poultry. Humans are also commonly bitten by all active stages.

The immature stages of A. americanum (larvae and nymphs) are known to parasitize all sizes of mammals and birds; however, in many locations research has shown that larger animals tend to be more heavily infested than smaller animals.
