This illustration reveals an identifying characteristic of the “rat flea’s”, Nosopsyllus fasciatus, head region.

N. fasciatus has a labial palpus that doesn’t extend beyond the tip of the first coxae. It’s closely associated with rats of the genus Rattus spp., and important in the transfer of plague from rat to rat, but doesn’t readily bite humans.
