Taiwanese-American mechanical engineering master's student w/ a Nikon COOLPIX P500 (some photos are from phone). Mostly interested in birds and arthropods.

I mainly ID Odonata, with most expertise in skimmers (Libellulidae) of the US and Taiwan. If any IDs look questionable they probably are; feel free to ask for justification/clarification. If there are question marks "?" in the comments for an ID, it is to indicate a degree of uncertainty.

Also feel free to @ me for identification help, though depending on the observation I cannot guarantee being able to improve upon the ID.
