Some morphological and biological features of Megacephala euphratica euphratica were examined. The life table of M. euphratica euphratica was investigated and the net reproduction rate (R-0), length of generation (T-0) and intrinsic rate of natural increase" (r(m)) were calculated in 2004 under labarotory conditions. The net reproduction rate (R-0) of M. euphratica euphratica (6.02), representing the total female birth rate with a mean length of generation (T-0) as 18.87 days, was determined, and the "intrinsic rate of natural increase" (r(m)) was calculated as 0.0981. The duration of pre-oviposition, oviposition and post-oviposition of the species, the shortest life span of both male and female, and the lowest and highest total eggs of female were also investigated. Some morphological features, like adult description and body size of the species, collected from Izmir, Mersin and Adana provinces, in 2001 and 2010, was given.
