english: For the most part, these adult fireflies don't get eaten because like their juveniles they can manufacture toxins that are repellent to birds and other insectivores, but somewhere along the line, one particular group of fireflies somehow lost the metabolic machinery needed to make their own protective toxins.
non_english: Najvećim delom, ovi odrasli svici ne budu pojedeni jer kao i njihovi mladi mogu da proizvode otrove koji su odbojni za ptice i druge insektojede, ali u nekom trenutku, jedna određena grupa svitaca je nekako izgubila metabolički aparat koji je neophodan za proizvodnju sopstvenih zaštitnih otrova.
