Figure 1

Caterpillar weight throughout the breeding season. Symbols depict mean ± s.e.m (log transformed) of dry weight of all caterpillars sampled from five different trees at each time point at each site; site is depicted by red (urban) or blue (forest) colours. Horizontal red and blue dashed lines represent hatch dates (mean ± s.e.m) for broods in the urban and forest site, respectively.
