These species, all of which are dragonflies, include the Mocha Emerald (Somatochlora linearis), Arrowhead Spiketail (Cordulegaster obliqua), and the Dragonhunter (Hagenius brevistylus).
Most of these new records represent common species except for the Dragonhunter (Hagenius brevistylus), Russet-tailed Clubtail (Stylurus plagiatus), Arrowhead Spiketail (Cordulegaster obliqua), Great Blue Skimmer (Libellula vibrans), and Blue-faced Meadowhawk (Sympetrum ambiguum).
There were also twenty-three species of small damselflies known as bluets identified, as well as a number of species whose populations were identified as relatively rare in our state, such as the comet darner and arrowhead spiketail
Pages 165 to 517 comprise dragonlies, the Anisoptera, organized by families as follows: Petaltails, Darners, Clubtails, Spiketails
, Cruisers, Emeralds, and Skimmers.
Virtually every dragonfly and damselfly you will ever see in Oregon is here somewhere, divided by type - petaltails, spiketails
, cruisers, darners, clubtails, emeralds, skimmers, broadwings, spreadwings and pond damsels - with descriptions and maps showing where they're most likely to be spotted and the likely months of the adult flight season.
The book is prefaced with a small introduction to Odonate biology and is suffixed with a number of addenda giving additional visual identification charts for Spiketails
, Bluets, and Dancers along with a chart delineating flight times and rarity of all species included in the book.
