      Certain beetles are endowed with eversible repugnatorial glands. Eleodes gigantea ... of both sexes ... when teased ... stand on their anterior and middle legs, holding the abdomen high up and spurting the contents of the glands right and left ... The liquid stains the human skin, has ... a peculiar, intensely penetrant odor, causing the eye to lachrymate.

Usage notesEdit

Almost the only natural usage is among zoologists as a technical term in describing particular classes of glands and their defensive secretions, as produced by animals such as certain insects. However, secretions of other animals such as skunks and some marine invertebrates also are described as repugnatorial.
