…you realize having documented the first Human Flea (Pulex irritans) on iNaturalist (despite not being a pet owner). Only accomplished because after suffering some days of nuisance (without actually catching one), you sneak back into the park where it was first encountered at the entrance of a burrow, actually manage to find one and take a photo of the small critter in situ, then catch it for later identification. I wrote sneaking, because you’d better not have your partner know that you might come home infestated with some more bloodsuckers just after getting rid of the previous ones - just for the sake of an observation…
