Seasonal Variation in the Little Sulphur Butterfly, Eurema lisa lisa, in Central Florida: How it Compares to Other Sympatric Eurema Species (Lepidoptera: Pieridae).

J. C. Daniels

Abstract


Eurema lisa lisa Boisduval & Leconte produces distinct wet and dry season forms in central Florida that, when compared with the other two sympatric, polyphenic Eurema species, Eurema nicippe (Cramer)and E. daira Latreille, shares numerous basic overall trends in wing color and pattern changes. A marked discrepancy in the trend appears, however, if proboscis length and forewing length are examined. The resulting contrarieties are discussed in regard to differences in adult winter activity, mobility and reproductive status.
