unusual facts about Methoxypyrazines


Harmonia axyridis

axyridis, like other lady beetles or ladybirds, uses isopropyl methoxy pyrazine as a defensive chemical to deter predation, but also contains this chemical in its hemolymph at much higher concentrations than many other such species, along with species/genus-specific defensive compounds such as harmonine.
