Horseshoe crab sexing?

Recommended Posts

Both males and females have stubby little wings, but males have more round wings, whereas the female's wings are squared off.

The best way to sex roaches is via the ventral segments, see here:


As you can see, the female has a much larger last ventral segment than the male. This method can be used for almost all Blaberids, including H.tenebricosa. :)
