Can ants predict rain?
1 JANUARY 2003
Ants in the kitchen, ants on fence posts – are these sign that rain is imminent? “No”, says Australian ant researcher and Charles Sturt University (CSU) PhD student, Mr Wayne Robinson. “I hear these stories regularly, but it has never been scientifically proven that ants can predict rain. It has been seen, however, that some ant species react to other environmental cues, such as increasing day length or higher temperatures, and build up the entrances to their nests or move fertile male and queen ants to higher ground at the start of ‘normal’ rainy seasons. Ants don’t know it is going to rain; like our farmers, they are just hoping it will be a normal season.” Mr Robinson, who lectures in environmental science in Queensland, is currently at CSU at Albury-Wodonga to further his PhD studies of ants on Fraser Island off central Queensland. But Mr Robinson says he is still keeping an open mind on the subject. “As with any scientific research, the answer can be changed with new evidence.”
