This firefly is the most common in the Iberian Peninsula. Both larvae and adults have the ability to emit light in their last abdominal segments through the oxidation of a protein called luciferin. This light emission has a sexual recognition function and although It is emitted by both males and females, it is the latter that emit light more frequently and intensely, since they are wingless (they do not have wings) and have to attract the males from the ground. Firefly larvae, like the one in the image "They are avid devourers of snails and slugs."
