Quick Facts

Other NamesDark flour beetle
Adult lifespan4 – 8 months
Duration of larval stageNot recorded
DistributionEurope, Africa, North America
HabitatGranaries, pantries, or kitchens where flour and grains are stored
PredatorsNot recorded
Seasons active fromNot recorded
Diet of larvae and adultsFlour, grain, poultry feed, rolled oats
Dark Flour Beetle
