Abstract
Mating action of the darkling beetle, Blaps kollari was investigated and analyzed. Insects were collected from Al-Nofoud desert at Al-Jouf area, KSA. The insect was identified using the available identification keys. To investigate details of mating, pairs of B. kollari were monitored over a period of one month. The results showed that the events of mating behavior of B. kollari could be grouped into three phases: (i) precopulatory courtship which was lasted for 10 +/- 3 min; (ii) copulation and ejaculation which was lasted for 12 +/- 5 min; and (iii) postcopulatory guarding which was lasted for 10 +/- 2 min
