Fiery Skipper (Hylephila phyleus) lives in open fields across North America. It feeds on grasses and leaves.
Fascinating facts about the Fiery Skipper
- Three genetic haplotypes dominate the fiery skipper, appearing in about 64.1 % of all sampled individuals, indicating they form the core lineages of the species. These central haplotypes, HphH1, HphH26 and HphH31, have given rise to other variants through mutation. Additional haplotypes such as HphH22 and HphH23 occur across continents, but the greatest haplotype diversity is recorded in South America.
- The fiery skipper was first recorded in Hawaii in 1970 and has since colonised every island except Lanai. After its initial discovery on Oahu, it quickly earned the label of an invasive butterfly because its larvae heavily graze on turfgrass. The widespread feeding damage has raised concerns for lawns and golf courses across the archipelago. Its rapid spread demonstrates how readily the species can establish new territories when suitable grass hosts are present.
- Research in Hawaii showed that fiery skipper larvae grow fastest when fed the experimental Bermuda-grass cultivar "FB-137". In that study, individuals on this diet outpaced growth on all other grasses tested, highlighting a strong preference for this particular turf. The result underscores how the species can exploit abundant grass resources to accelerate development. Such rapid growth contributes to its potential as a pest in managed lawns.
- When checking a lawn for fiery skipper caterpillars, the most effective approach uses a spray of either 0.0015% pyrethrins or 0.25% detergent mixed with four litres of water. This solution is applied to a precisely measured circular area of 1,860 cm², which the research shows yields the highest detection rates.
- After the detection spray is applied, observers should count the larvae within five to ten minutes, a narrow window that captures almost every individual present. Studies report that this brief period secures a detection success of roughly ninety to one hundred percent, making it a near-complete census of the pest population.
