These are the day-time equivalents of their more famous night-flying and luminous relatives. This species is also called Sap-bucket beetle and the Winter firefly, and appears just before spring, either on tree trunks, buildings or in sap buckets. They feed on maple sap and sugar, and have actually become a pest in some regions, since so many of these drown in the maple sap buckets before the sap gets changed into syrup; as you can imagine, removing a load of beetles from a bucket of which there is about 30+ of around the maple forest, may take a very long time. Diurnal fireflies (non-lighted species) can be fonud flying slowly at low heights across fields (more common after rain since they prefer damp habitats) and can be found resting on plants and grass near ponds and marshes.
