Biology of Pseudopelmatops View in CoL species and their possible relationship with Sesiidae (Lepidoptera)

Xiao-lin Chen and Yong Wang observed the biology and behaviour of Pseudopelmatops angustifasciatus and P. continentalis in the field at Tianmu Mountain, Zhejiang Province in the summer of 2013 and 2014. We often found adults of these two species on or near a ‘blocking cap’ ( Fig. 157 View FIGURES 157 – 159 ) outside the openings of mines made by larvae of Sesiidae ( Fig. 159 View FIGURES 157 – 159 ) in stems of Rubus peltatus Maxim. (Rosaceae) . The flies spent long time on or near these caps. We observed a male of P. angustifasciatus even staying there for one day and night ( Figs. 160, 161 View FIGURES 160 – 163 ). We also observed interaction between a male and female of P. angustifasciatus beside one ‘blocking cap’ ( Figs. 162, 163 View FIGURES 160 – 163 ), but mating or oviposition were not observed. Two Diptera larvae were found in one ‘blocking cap’ ( Fig. 156 View FIGURE 156 ). We extracted DNA and partially sequenced the 28S and COI genes from one larva, then carried out molecular analysis with the adult data. The results of the 28S (Table S4, Fig. 154 View FIGURE 154 ) and COI (Table S4, Fig. 155 View FIGURE 155 ) analyses grouped this larva with Pseudopelmatops adults, although they did not resolve whether it is conspecific with either P. angustifasciatus or P. continentalis .

Several open puparia morphologically similar to that of Soita also were discovered in the lower part of stem mines that extended to the roots of R. peltatus ( Fig. 166, 167 View FIGURES 164 – 167 ) in the early spring and winter of 2014. We highly suspect that these puparia are one or more species of Pseudopelmatops . To guide our future study of the biology of Pseudopelmatops , we hypothesize that in summer or early autumn, the female of Pseudopelmatops might lay eggs in the ‘blocking cap’, and the eggs hatched into larvae there. As the larvae develop (perhaps as second or third instars), they may enter the mine and bore deeper, eventually reaching the root of R. peltatus where they pupate and overwinter.
