Something has been bugging Colby geneticist David Angelini.

How, Angelini wonders, can a single species (in this case the soapberry bug) produce two distinctly different forms, one with long wings and one with short, that are not linked to sex? What is the genetic mechanism that causes the wings to develop differently?

"Why does it not overshoot the long form? he asked. "Why doesn't it undershoot the short form? Why doesn't it end up somewhere in the middle? That's an open question."

And a question that the National Science Foundation wants him to answer.
