How is the caterpillar data collected?

We use a method called 'branch beating' to dislodge all caterpillars from a number of marked branches at each site. Any caterpillars that are dislodged are preserved in ethanol, and then a sample is taken for DNA sequencing More information about the branch beating technique can be found here: https://doi.org/10.1086/705241

What caterpillar species are included in the analysis?

The top 20 most abundant species that are included in the analysis are (in order of decreasing number of samples): Operophtera brumata Agriopis aurantiaria Operophtera fagata Ypsolopha ustella Erannis defoliaria Orthosia cerasi Cosmia trapezina Epirrita christyi Conistra vaccinii Agriopis marginaria Phigalia pilosaria Pandemis cerasana Orthosia incerta Ypsolopha parenthesella Eupsilia transversa Orthosia gothica Epirrita autumnata Agriopis leucophaearia Hydriomena furcata Campaea margaritaria
