Fig. 5. Distance covered in stage 2 versus total length. Mean values calculated for each individual are plotted ± S.E.M. (N=7–11 escapes). Equations of linear regressions for stage 2 distance are y=0.482x+0.0097 (r²=0.69, P=0.0002) for larvae (open circles and dashed line) and y=0.380x+0.274 (r²=0.91, P=0.0008) for adults (filled squares and solid line). Distance travelled in stage 2 does not differ significantly between the two life stages (P=0.196). Stage 2 distance is significantly positively correlated with total length.
