Reputedly these are the largest termites in North America. The reproductives measure about 30mm with wings on, and about 15mm without wings. These are large clumsy fliers that are hard to miss during their emergence period. I found very interesting how readily they drop their wings upon landing. I grabbed a couple in mid air and dropped them in my daughter's sand bucket for observation. The first thing they did was to twist and bend and brake off their wings. I could not, however, see exactly how they do it. I will continue with my observations until I figure it out.
