  DARKLING BEETLES (TENEBRIO)   (Site not responding. Last check: 2007-10-25)
Beetles, along with all their other insect kin (true bugs, flies, bees, wasps, ants, on and on), are members of the phylum Arthropoda, a word meaning jointed legs.
Beetles are arthropods, and like all members of their phylum they wear their skeleton on the outside like a suit of armor.
Mealworms and darkling beetles are rarely seen in the wild, but when they are, it is likely to be in a field where wild grasses flourish and seeds are plentiful.

  Darkling beetle - Wikipedia, the free encyclopedia
Darkling beetles are a family of beetles found worldwide.
The larval stages of several species are cultured as feeder insects for captive insectivores, and include the very commonly known mealworms and superworms, and the lesser-known mini mealworms.
Raising darkling beetles from larvae through adulthood can be a rewarding biology project for lower school educators.

At the outset of this study, the role of the darkling beetle and the housefly in the transmission of turkey coronavirus was unknown.
The housefly and the darkling beetle are both inhabitants of poultry facilities and were demonstrated to have the potential to act as mechanical vectors of TCV.
The role of the darkling beetle in the transmission of TCV is a concern, however, the scope of the transmission appears limited to the poultry facility.

Direct effects of darkling beetle activity are almost solely the result of these insects feeding on either poultry feed or building insulation and structures.

 Do adult of larvae darkling beetles respire at a faster rate   (Site not responding. Last check: 2007-10-25)
Darkling beetle larva (mealworms) are less active and less complex than adult darkling beetles therefore they may have lower rates of respiration than adult beetles.
