Invertebrate allomones that deter vertebrate predators

7 Invertebrate allomones that deter vertebrate predators 10.7.1 Taste aversion to invertebrate prey 

At overwintering sites of the monarch butterfly [Danaus plexippus) in Mexico, only one of the three local mouse species, Peromyscus melanotis, actually feeds on the butterflies. The monarchs contain cardiac glycosides (CG) and pyrrolizidine alkaloids (PA). All three species of mice have similarly low avoidance thresholds to PA (specifically, monocrotaline). But P. melanotis is less sensitive to CG (specifically, digitoxin) than the other two, Reithrodontomys sumichrasti and Peromyscus aztecus. Laboratory tests indicate that PA is toxic to young mice.
