From: Seasonal cues induce phenotypic plasticity of Drosophila suzukii to enhance winter survival

Fig. 1

Drosophila suzukii exhibit phenotypic plasticity in size and melanization in the field. a Seasonal changes in wing length of female D. suzukii collected from the field (Hood River, OR, USA) in apple cider vinegar baited traps. Both wing length (mm) (left axis) and temperature (°C) (right axis) are represented on the Y-axes, and chronological time (between August 2011 to February 2013) is represented on the X-axis. Male wing length is plotted in blue and female wing length is plotted in red. Temperature is plotted in gray. Mean daily air temperatures are plotted from the Hood River, Oregon AgriMet Weather station (HOXO) [73]. b Seasonal change in photoperiod from August 2011 to February 2013. The day-length (in hours) is shown on the Y-axis and date is shown on the X-axis. Day-length values were plotted for Hood River, Oregon [74]. c Percent summer morph (lighter pigmentation) and winter morph (darker pigmentation) of female (left) and male (right) D. suzukii from August to December in Hood River, OR during 2011. Summer and winter morphs are represented by black and gray respectively
