There are a number of moth species that have brown wings and a red body. Determining the specific species requires looking closely at the size, shape, markings, and other physical characteristics of the moth. Some common moths with brown wings and red bodies include the rosy maple moth, the scarlet-bodied wasp moth, the red underwing moth, and certain Underwing moths in the genus Catocala. Properly identifying the moth takes patience and careful observation.
Distinguishing Physical Features
When trying to identify a moth with brown wings and a red body, pay close attention to the specific shade of the brown and red coloration. Also note the size and shape of the wings, whether the wings are solid brown or have patterns of lines or spots, and whether the edges of the wings have any distinguishing scallops or shapes. The intensity of the red on the body can also be an important clue, as some have vivid scarlet bodies while others may be a darker maroon.
Examining the moth underneath the wings is also essential. Many species have distinctive markings or colors on their abdomens and thoraxes that are only visible when the wings are at rest. The antennae can also be telling, with feathery, thin, thick, or serrated variations from species to species. Being attentive to all these details will aid greatly in determining the exact species.
Distinguishing Behavioral Features
In addition to physical characteristics, the habits and behaviors of moths can provide helpful clues to their identification. Factors like what plants or trees they are found on, what time of day or night they are active, their flying patterns, what caterpillars and cocoons they form, and other behavioral traits can all point towards certain species.
Getting a chance to observe the moth while it is alive and in its natural habitat will provide the best opportunity to note these behaviors. However, even a motionless specimen can offer some hints by noting where and in what situation it was found. With close examination and reasoning, the behaviors and lifestyle of the moth can be inferred.
Red Underwing Moth
One moth with brown wings and a vivid red body is the red underwing moth (Catocala neogama). This large moth has forewings that are brown with a textured, mottled appearance. The hindwings are mostly black with broad red bands along the inner margins, which gives rise to their common name. When the wings are at rest, the red of the hindwings is covered up, leaving just the brown forewings visible. This provides camouflage from predators.
Red underwing moths have a thick, hairy body that can range from a bright scarlet to a deep maroon in color. They have a wingspan of 3 to 4 inches. These moths can most often be found in woodlands and forests, especially among oak trees. The caterpillars feed on the leaves of oak, willow, maple, birch, and other deciduous trees.
Rosy Maple Moth
The rosy maple moth (Dryocampa rubicunda) is a small, brightly colored moth with vivid red and yellow on its body. The forewings are yellow to olive brown with blurred patchy bands of a darker color. The hindwings are slightly paler brown and smaller in size.
The head, thorax, and abdomen are covered in furry red and orange hairs, providing a brilliant splash of color. Two tufts of raised black hairs project forward from the thorax. This species has a wingspan of just 1 to 2 inches, making it smaller than many other red and brown moths.
Rosy maple moths are native to North America and can be found throughout the eastern United States and southeast Canada. As their name suggests, they commonly live in maple forests. The larvae feed on the leaves of maple trees but may also eat from oak and beech.
Scarlet-Bodied Wasp Moth
The scarlet-bodied wasp moth (Cosmosoma myrodora) earns its common name from the vivid red-orange coloration on its body. Its forewings are dark brown with an olive tint and have lighter, translucent crescent shapes along the edges. The hindwings are smaller and uniformly orange-brown.
These moths have a bright red head and thorax that contrasts sharply with the darker wings. The abdomen is also ringed in red and black bands. Antennae are thin and feather-like. Scarlet-bodied wasps have a wingspan between 1.5 and 2 inches. They are found primarily in Central and South America, inhabiting tropical forests and jungle areas.
The caterpillars of this species feed on plants in the dogbane and milkweed families. The striking red and black coloration serves as a warning signal to potential predators that the insect may be toxic or unpalatable.
Underwing Moths
Several moths in the genus Catocala display cryptic brown upperwing coloration coupled with vibrant red underwings. These include the magnificent underwing (Catocala magnifica), the Ulalume underwing (Catocala ulalume), and the sweet gum underwing (Catocala dulciola).
At rest, these species conceal the hindwings, which are black edged with red, orange, or yellow bands. This startles predators when the brightly colored underwings are suddenly exposed in flight. Upperwings range from light brown to dark charcoal shades with faint zigzag patterns. Wingspans vary from 2.5 to 4 inches across the genus.
Underwing moths live throughout North America in deciduous forests and woodlands. Larvae feed on the leaves of trees including oak, hickory, maple, and many others. The bark-like camouflage of the forewings provides excellent concealment when at rest on tree trunks.
Identification Process
Identifying an unknown moth with brown wings and a red body requires carefully observing and documenting its physical features. Noting details like the wingspan, exact wing colors and patterns, body coloration, antennae structure, and any markings on the thorax, legs, or abdomen. Photograph the moth from multiple angles for review.
Compare these observations against guides, photos, and species descriptions in resources like field manuals, websites, and smartphone apps. Take into account where and when the moth was sighted. Match the characteristics and behaviors with those of known species. Consider reaching out to experts through local nature organizations for assistance if needed.
With deductive reasoning, patience, and a good reference library, an unknown moth can be pinned down to its precise species. Proper identification provides satisfying closure and builds observational skills over time.
Key Families and Genera
There are certain moth families and genera that are most likely to contain species with brown wings and red bodies:
– Arctiidae – This family includes tiger moths, lichen moths, wasp moths, and woolly bears. Genera like Grammia, Pygarctia, and Virbia contain red and brown species.
– Noctuidae – A very large family including owlet moths and underwings. Genera to look at include Catocala, Caenurgina, and Macrochilo.
– Saturniidae – The giant silk moths. Some Hemileuca species are brown with red undersides.
– Lymantriidae – The tussock moths, including the rosy maple moth.
– Lasiocampidae – The eggars, snout moths, and lappet moths. Some Malacosoma species are brown with reddish hairs.
Focusing the search within these moth families will significantly narrow down red and brown moth candidates for identification.
Conclusion
Identifying an unknown moth is a rewarding hobby that builds observational skills. When presented with a moth of brown wings and a red body, pay close attention to its precise physical attributes and behaviors. Compare these clues to reference materials to deduce the species. Likely candidates include the rosy maple moth, underwings in the genus Catocala, the scarlet-bodied wasp moth, and others. With patience and practice, the precise identity of many beautiful and intriguing moths can be uncovered.
