Triatoma mexicana</I> is one of the triatomine species whose biologic development is yet unknown, but it is frequently reported to be infected by <I>Trypanosoma cruzi</I>. In this research, we explore the life cycle and reproductive and feeding patterns of <I>T. mexicana</I> under laboratory conditions. Ten female and 12 male insects were  collected  to  make  up  a  artificial  colony. The deposited eggs were maintained in the laboratory under 3 different conditions: 27°C and 66% humidity, 26°C and 35% humidity and 19°C and 45% humidity (these last were room temperature and humidity). Nymph and adult insects were fed on CD-1 mice and chicken once a week in order to study the alimentary preference of this triatomine species. Our observations were that 71.5% of successful hatching took place at 27°C and 66% humidity, therefore were the better environmental conditions for <I>T. mexicana</I>. Out of successfully hatched ones, 8% survived till adulthood, in which 2.5% were males and 5.5% were females, at the end of 338.66±35.38 days. In the adult phase, the insects survived between 100 and 190 days. In 1st to 4th instars, <I>T. mexicana</I> was fed for 1-3 times; in 5th instar for 1-4 times and in adulthood for 3-7 times. Each feeding occurred at an interval of 15-34 days. The morphologic characteristics of every instar phase  are  described  by  photographs.  Through  this  research,  biologic  cycle  and  survival  conditions  of <I>T. mexicana</I> were explored for the first time.
