Growth Pattern Responses to Photoperiod across Latitudes in a Northern Damselfly
Figure 3
Head width of field collected adults of C. johanssoni originating from three different latitudinal regions across Sweden.
Shading symbols indicate mean (95% CI) adult head width of different populations in each sampled region. Note that individuals from the second population sampled from the northernmost part of Sweden (marked with grey shading) were not included in the laboratory rearing experiment.
