We annoyed some flies this week. The plan was to powder them and then track them via camera traps. Usually what happens is that flies groom all the powder off except for a bit at the top of their thorax, and then they are easily seen in a group. That did not happen with our newer evolved populations: these flies groomed everything off within 24 hours. So it is back to hand painted flies for us.
Congratulations to Isabel Rojas-Ferrer on the successful defense of her master’s thesis! She gave a great talk, her committee was happy, and no blood was spilled in the process.
