They prey on Semisulcospira libertina snails. [8] They have six to seven instars. [3] The fireflies emerge from underground pupae around June. [5] Maturity is reached in more than one year. [7] Adults live for less than three weeks, and they do not eat anything. [5] Their flash communication system is known as the "complex system".
A molluscivore is a carnivorous animal that specialises in feeding on molluscs such as gastropods, bivalves, brachiopods and cephalopods.Known molluscivores include numerous predatory (and often cannibalistic) molluscs, (e.g. octopuses, murexes, decollate snails and oyster drills), arthropods such as crabs and firefly larvae, and vertebrates such as fish, birds and mammals.

Some fireflies — nicknamed femme fatale — mimic another species' light pattern to attract males, kill and eat them, Lewis said. Climate change is another worry for fireflies, Lewis said.
