Trinucleotide microsatellite loci for the peppered moth (Biston betularia)

Fourteen polymorphic trinucleotide microsatellites were isolated in the peppered moth, Biston betularia, using an enrichment protocol. Moderate to high allelic diversity (three to 22 alleles per locus) was found in a sample from northern England. We are currently using these markers to study the population structure of B. betularia in northern England, where a cline for melanism still exists.
