I have updated my dragonfly book. Now it is two volumes, the first devoted to damselflies, the second, to dragonflies. The critters in the book include species Erika and I have seen in our travels through the United States and during a dragonfly tour of Costa Rica. Accompanying text covers identification, ecology, and behavior. Two .pdf files, compatible with most, if not all, platforms, are available for $9.99 each. Hardcopy formats can also be purchased, but, since they are produced on a per-order basis, they tend to be a bit pricy. Details and sample pages can be found at either of these two links:
