We report the detection of hypervariable markers in the satyrid butter
fly Bicyclus anynana (Butler) using the human-derived minisatellite pr
obes 33.6 and 33.15. A highly informative fingerprinting system was es
tablished, and, uniquely to date, probes 33.6 and 33.15 were found to
hybridize to an identical single hypervariable locus at low stringency
in this species. Segregation analysis was performed using two familie
s, consisting of two parents and 15 and 16 offspring, respectively. Me
ndelian inheritance was confirmed. The number of alleles present and t
he level of heterozygosity were determined by fingerprinting 18 unrela
ted individuals: 11 alleles were observed, and 83% of individuals were
heterozygous. These data show for the first time that hypervariable m
arkers occur in the genome of a butterfly species; they suggest that a
dditional loci may be revealed by hybridization with other minisatelli
te probes. Both probes detected one other independently segregating po
lymorphic locus to which 33.15 hybridized more intensely, allowing gen
otypes to be characterized. It is possible that similar methods could
yield useful results in other Lepidopteran species.
