Orange Head Roach Gender?

[Arthropod Hunter]

Hello , how do i know the genders of my orange head roaches? (they all look the same and i'm confused).

With most roaches you can tell by looking at their underside. The very last segment will be much thicker on females than it will on the males

Males have large wings and tend to be thinner. Females tend to be wider.

Both males and females of this species will be winged adults and they can be difficult to distinguish from one another at a glance.

The best way to tell E. posticus sexes apart is by looking at the tip of the abdomen: male will have a small white patch and females will not. Take a look at a few adults and you'll see what I'm talking about =)

Otherwise, as previously mentioned, the size of the last abdominal sternite is pretty much universal in roaches. Flip a few adults over and you should begin to notice an obvious size difference in that last ventral (belly) segment toward the tip of the abdomen... females will have a larger segment and males will have thinner segments. Try differentiating the sexes of other adult roach species using this method for practice, too.
