Odontomachus worker longevity (Kaitlin, North America)

Dear AntAsk team,

I've been rearing a colony of North American Odontomachus for about three years now. Recently I separated about 200 workers from the main colony for the purposes of another project which has since been completed. Reluctant to return them to the original colony for fear of contamination, I have been keeping these workers separate and supplying them with sandy soil, some dried wood, a cotton ball of water, a cotton ball of sugar water and biweekly termites or pinhead crickets. However, I was startled to find that over three months later I still have about 85 or so of the separated workers left perfectly alive and well. I was wondering, what is the average longevity of most Odontomachus workers? Is this common for them to live this long?

Thanks for your help,

Dear Kaitlin,

Thank you for contacting AntBlog. Your experiments with Odontomachus trap-jaw ants sound interesting. To address your question, we contacted an expert, Andrew Suarez, who has lots of experience rearing Odontomachus colonies in the lab. Here is what Andy had to say:

"We have maintained a number of Odontomachus species in the lab, and have found workers to be quite long lived under lab conditions. For a few of the larger species, we have had workers live for over a year. Six months, however, is definitely not unusual."

Good luck with your trap-jaw ant colonies!
