Sexing wasps in the genus Ammophila (abdominal tergites) - Ammophila - male

Sexing wasps in the genus Ammophila (abdominal tergites) - Ammophila - Male
Tonopah Desert, Maricopa County, Arizona, USA
May 4, 2015
Size: 20mm

SEX: (male)
The sexual dimorphism in this subfamily is very subtle. Finding the gender in this genus and many related wasp genera may be accomplished with a clear image of the antennae segments or flagellomeres, the abdominal segments and the tarsi of the forelegs.
flagellomeres - male = 11, female = 10
tergites and sternites - male = 7, female = 6
tarsal combs on the front forelegs = females only
