Moths in Disguise: these are all just harmless moths that have developed the ability to mimic wasps, bees, and/or hornets

Moths are exceptionally skilled when it comes to mimicry, and there are hundreds of moth species that rely on that tactic as a way to protect themselves from predators. Their disguises are numerous and varied, but hymenopteran mimicry is particularly common, especially among the moths that belong to subfamily Sesiidae and family Arctiinae.

Some of their disguises involve more than just a physical resemblance -- there are some moths that also engage in behavioral and/or acoustic mimicry, meaning that they can imitate the specific sounds and behaviors of their hymenopteran models. In some cases, these moths are so convincing that they can even fool the actual wasps/bees that they are mimicking.

Such a detailed and intricate disguise is unusual even among mimics, and researchers believe that it developed partly as a way to trick the wasps into treating the mimic like one of their own. Wasps tend to prey upon moths (and many other insects), but they are innately non-aggressive toward their own nest-mates, which are identified by sight -- so if the moth can convincingly impersonate its model, then it can avoid being eaten by predatory wasps.

There are many moths that can also mimic hornets, bumblebees, and carpenter bees.

Moths are some of the most talented mimics in the natural world, as illustrated by their mastery of hymenopteran mimicry. But it's not just bees, hornets, and wasps -- there are many other forms of mimicry that can be found among moths, and the resemblance is often staggering.

Moths deserve far more credit than they receive, to be honest, because they are so incredibly interesting/diverse.
