Darkling beetles are insects that are generally black in colour hide during the day and come out during the dark period to feed. They belong to the beetle family Tenebriondae and have been associated with diseases like salmonella (Loeffler), respiratory viral diseases and even worm infestations of chickens. According to (Falomo 1986), the darkling beetle is known to feed on sick birds, dead birds and other organisms and is associated with the spread of Gumboro and Mareks diseases among flocks.
Darkling beetles eat feed.
