The larva of Leucorrhinia patricia Walker (Odonata: Libellulidae)


The final-stadium larva of Leucorrhinia patricia Walker is described from six exuviae with associated teneral adults collected in northern British Columbia. L. patricia belongs to the group of nearctic Leucorrhinia that has larvae with three ventral stripes. The larvae are very similar to those L. hudsonica (Sélys) larvae that are small and lack dorsal spines. Several characters help to separate these species, at least in the western part of their range; length of the epiproct and patterns of the profemora and abdomen. The preparation of a more definitive key awaits the analysis of more material of L. pafricia and L. hudsonica.
