The toxin of common furrow bee primarily serves as a defense mechanism and means to subdue prey. When common furrow bee utilizes its sting, it introduces a mild venom into targets, causing discomfort or deterrence rather than serious harm. Humans may experience localized pain and swelling if stung. Birds and small mammals, such as rodents, can also be affected by the defense sting, leading to similar mild reactions. Other arthropods, including spiders and insects, may be incapacitated or deterred by the toxin, increasing common furrow bee's chances of survival and success in capturing prey.
