Does Gender Affect Wing Size?

Taryn U

In this experiment we measured the right top wing of 25 male butterflies and 24 female butterflies.  We did this experiment to see which gender of butterfly has the longest wings.  An uncertainty is that there could have been some inaccuracy in measuring.  Also, these butterflies were all reared in different homes/environments which could have affected their size.  We learned that the male has bigger wings on average.  According to our results, the female's wings are smaller by almost two millimeters.
