Dear colleagues, This one is for the entomologists in the crowd. I have been doing some surveys of intertidal crabs along the Chittagong coast (Bangladesh) and have been noticing truly impressive abundances of two dragonfly species (either that or one with strong sexual dimorphism) along the beach. They seem to regularly land and spend some time on sediments that have been disturbed by the crabs I am studying. I am familiar with the mud puddling behavior of butterflies and was curious if dragonflies do the same. Could they be getting minerals from these sediments? Are there dragonflies associated preferentially with brackish habitats? Is species identification of these insects manageable for a non expert or is this a rather difficult insect group to ID? Comments and ideas are most appreciated! Cheers,
