Parachartergus apicalis is a species of wasp in the Polistinae subfamily, found in the Neotropics.

False swarming can also occur when strong winds prevent foragers from entering the nest.

[4] They have been recorded to tend species of treehopper, plant sap-feeding insects, during the daytime, an example of a mutualistic relationship.

At night the carpenter ant species, Camponotus atriceps will tend the nymphs.

These are thought to be examples of Müllerian mimicry, since predators pay a high penalty for mistaking a Lepidopteran for the wasp and there is a small reward from correctly identifying the Lepidoptera, since they are bitter tasting and covered in scales.
