Summary
Euchromiina is a subtribe of the diverse family Erebidae, known for their mimicry of wasps and vibrant coloration, primarily found in Neotropical regions. Established by Butler in 1876, it consists of many species that play significant roles in ecosystems as pollinators and herbivores.
Physical Characteristics
Euchromiina species are often characterized by their vibrant colors and patterns, which mimic the appearance of wasps. Many species possess hairy bodies typical of the Arctiinae.
Identification Tips
Look for bright colors and patterns on wings; many species mimic wasps. The presence of hindwings that are often brightly colored can be a distinguishing feature.
Habitat
Primarily found in tropical and subtropical regions, particularly in the Neotropics.
Distribution
The majority of Euchromiina species are distributed in the Neotropics, with several species found in more temperate regions.
Diet
Adults primarily feed on nectar from flowers, while larvae (caterpillars) may feed on a variety of plants, often preferring herbaceous species.
Life Cycle
Euchromiina undergo a complete metamorphosis, including egg, larva (caterpillar), pupa, and adult stages.
Reproduction
Reproduction generally involves mating in which males locate females using pheromones; eggs are laid on host plants that caterpillars will feed on.
Predators
Predators include birds and other insectivorous animals that are often deterred by the warning coloration that mimics wasp patterns.
Ecosystem Role
As pollinators, adults play a role in plant reproduction; their larvae contribute to the food web as herbivores.
Collecting Methods
- Light trapping
- Netting during active hours
- Using bait traps
Preservation Methods
- Pinning
- Alcohol preservation
- Paper envelopes for dry specimens
Evolution
Euchromiina are considered closely related to the Ctenuchina, showcasing evolutionary adaptations for mimicry in co-evolving ecosystems.

Misconceptions
Some may confuse Euchromiina with true wasps due to their mimicry; however, they are harmless moths.
