Harmonia axyridis (Pallas) is abundant in the Northeast and Southwest and is a recent addition to the North American coccinellid fauna. Due to it commonness and status as an invasive species, it is frequently used in field and lab experiments. A lack of knowledge about the sex of H. axyridis can be a major hindrance to research on the ecology and fecundity of the species. This study will describe a methodology that allows
H. axyridis to be sexed without dissection. Copulating
H. axyridis pairs will be separated and dissected to determine the proportion of male-female copulation and to determine the reliability of assuming that the individual on the bottom is consistently female and the individual on the top is male.
