Sawfly larvae

Pine sawfly lab

We have two goals: 1) to investigate the costs and benefits of cooperation and cheating in chemical defence under varying ecological and social conditions and 2) to investigate the costs and benefits of low signal intensity strategy. As a study species we use gregarious, chemically defended but cryptically coloured pine sawfly larvae (Neodiprion sertifer, Diprion pini). We use multiple approaches such as molecular phylogenetics and avian vision modelling to study the co-evolution between defensive colouration and other defence traits. We also use artificial selection experiments to test the trade-offs between defence and other fitness traits, and behavioural experiments to test the signal value of different visual traits of defended prey or how social and ecological conditions affect individuals' contribution to cooperation.
