help Scarlet-bodied wasp moth FAQ
Is the scarlet-bodied wasp moth actually a wasp?
No, the scarlet-bodied wasp moth (Cosmosoma myrodora) is a moth in the family Erebidae, not a true wasp. Its vivid red body and clear wings are an example of Batesian mimicry, imitating the appearance of stinging insects to deter predators.
Where can the scarlet-bodied wasp moth be found?
Cosmosoma myrodora is native to the southeastern United States, particularly Florida and other Gulf Coast states. Adult moths are most commonly observed during the warmer months and are frequently attracted to lights at night.
What do scarlet-bodied wasp moth caterpillars eat?
The larvae feed primarily on plants in the family Asteraceae, especially climbing hempvine (Mikania scandens). Adult males also visit certain plants to collect pyrrolizidine alkaloids, which they do not consume for nutrition.
Why do male scarlet-bodied wasp moths gather plant toxins?
Males collect pyrrolizidine alkaloids from specific plants and package them into a chemical courtship gift that is transferred to the female during mating. These compounds render both the female and her eggs distasteful to predators such as jumping spiders.
