Mallard × Mexican Duck (Anas diazi × platyrhynchos)Observer
tristanmcknightDescription
I think this is a Mexican duck: olive yellow bill on “female” mallard color during breeding season, no curly tail feathers, color distinction between head and body. Though it looks like there’s a little mallard introgression in the hint of green to the dark marks on the head and fairly white tail. Should I call it a hybrid?
The last picture (with the female mallard and a Muscovy duck) is included because I liked seeing the contrast between the true mallard and the Mexican.

Red-footed Cannibal Fly (Promachus rufipes)Observer
tomandjillDescription
Tentative id based on the red toes, tibias and black femurs. These fell on the ground. A female with a male and a third attempting to join. There was a Polistes wasp caught up in the frenzy, but was dead by the time they all hit the ground. Maybe hinei instead of rufipes?

Table for two... termites were swarming and these were just some of the predators taking advantage of it.

I'm wondering if it's possible to make this into Laphria winnemana. I can't make out the processes on tergite 6 but perhaps there's enough detail showing to make a determination. @tristanmcknight
