Jeremy Tatum writes: I recently made a bad mistake (since corrected) in mistaking a libellulid for an aeshnid. Dr Rob Cannings offers the following hint (not a sharp, invariable rule, but pretty good most of the time): Aeshnidae species usually perch vertically, hanging down (not all do, e.g. Aeshna sitchensis often sits flat on ground); Libellulidae species often perch horizontally.
