Prolimacodes is a of slug caterpillar moths in the Limacodidae, established by William Schaus in 1896. The genus contains at least seven described distributed across North and Central America. Caterpillars in this genus are commonly referred to as "slug caterpillars" due to their distinctive reduced-leg locomotion. are attracted to ultraviolet light sources and are documented in citizen science observations.

Identification
can be distinguished from other Limacodidae by wing shape and pattern; the includes with triangular or rounded forewings. The "skiff moth" refers to the boat-like appearance of some species when at rest. Larvae are slug-like with reduced , moving with a characteristic gliding motion rather than crawling. Specific species identification requires examination of genitalia or detailed wing pattern analysis.

Distribution
North America and Central America. Documented observations include the United States (Vermont, Kansas, and other states) and presumably extend through the 's known range.
Seasonality

Behavior
are and attracted to ultraviolet light sources. Larvae exhibit the characteristic slug-like gliding locomotion typical of Limacodidae, using reduced and abdominal surface contact for movement.
Human Relevance
Documented in citizen science projects such as National Week and iNaturalist. The serves as an accessible subject for moth observation and photography due to its attraction to artificial light sources.
