Congratulations are due to Tamara on winning a runner-up prize in the best short talk category at this year’s Australasian Evolution Society conference! Tamara presented a great talk on how larval rearing density affects investment in antennae and testis size in male gum-leaf skeletonizer moths. Basically, moths reared at low densities put all their efforts into antennal growth (presumably because they ‘think’ will need to be super-sensitive to find females), but at high densities put their investment in testes instead (because of anticipated higher levels of sperm competition – we think). It was a really elegant experiment and beautifully presented.
