Not all mantids have wings that cover the abdomen. Developed wings are always a sign of an adult. No need to count segments on adults as there are often differences in size and the abdomens on most species are quite different. The females' ends in a downward point and the males has an upturned cup shape. Often times adult female abdomens are wider than males. Experienced keepers should be able to tell adult gender at a glance.Fully grown wings that cover the abdomen (both male and female) may be considered as one of the signs of sexual maturity. You can also determine the sex by counting the number of segments on the abdomen. In adult males, you can see eight segments and in adult females, 6-7 are visible. There is one more distinguishing feature between male and female –the antenna. Males have feathery antenna and females have short and thin antenna.
