I missed an arthropod last Sunday, and my friends didn't let it go. So -

🚨 ARTHROPOD OF THE OTHER DAY 🚨

Hamadryas chloe, the Chloe cracker, is a species of cracker butterfly in the family Nymphalidae. It is found in Suriname, Peru, Colombia, Bolivia, and Brazil.

They acquired their common name due to the unusual way that males produce a "cracking" sound as part of their territorial displays. Male cracker butterflies are known for their ability to make a cracking noise with their wings, which is believed to either be for mating or to ward off rival males. They use trees as courting territories, as shown by experiments. They prefer to perch on trees with bark that matches their wing coloration, while the presence of food, position of trees along flight routes, tree size, bark texture, and lichen cover are not associated with the frequency of perching on the trees.
