Image of Polistes apachus de Saussure 1857

Description:

This photo shows some holes in the caps of the nest. I was wondering if perhaps some other wasp like the little Ichneumon that was visiting a couple of days earlier may have parasitized the nest, though I'm surprised anything could get past these to do so. The second and third photos are from the earlier observation on JUly 17: https://www.inaturalist.org/observations/3692962
