A pair of adult Dermestes maculatus was introduced into separate tubes containing each fish species to serve both as food and oviposition medium. Some eggs laid were collected and placed on each fish substrate in glass tubes for incubation and measurement. On hatching the larvae were separated into individual tubes (2.2 cm 15 cm) containing 10 g of each fish species and kept under observation. The developmental stages were obtained from each substrate for measurement using Nikon Optiphot phase contrast microscope equipped with a drawing tube. The result indicates that larval instar 1 bred on mixed substrates was significantly shorter (p<0.05) than those bred on the other fish substrates. No statistical difference was observed among other larval instars on each of the different fish substrate. However, the fourth larval instar bred on Synodontis and Clarias were significantly longer (p>0.05) than those bred on the other substrates. There were significant differences in length among the various developmental stages with prepupae and pupae being significantly longer (p<0.05) than larvae.
