Yes.
Definitely not Monobia, however.

 
Thanks, Does the striping va
Thanks,
Does the striping vary within the species? For example does one Euodynerus hidalgo look like all the others or can there be some variation.

 
Variation.
Often there are at least geographic "clines," where those individuals in one area will be very dark, those individuals in another area (usually arid habitats) will be very pale or yellowish. There can be sexual dimorphism and simple individual variation as well. That is why 'structural' details are more important in identification than color patterns. Usually:-)

Thanks for the information.:-)
