I guess the "chin" in DTB is the labium, the jointed structure under the mandibles. That is fairly variable in color." Dennis I.D. verified by Alan Myrup "Yes, your label, Leucorrhinia intacta, (Dot-tailed Whiteface) is correct. The ventral view of the subgenital plates is the key." Alan Characteristics of Female 1. Amber colored inner wings 2. Segments two through 7 have yellow dorsal spots. Segment seven spot is almost a square. 3. White face 4. Small black basal wing spots 5. Black legs 6. "Female subgenital plate 2 parallel pegs 1/4 as long as Segment 9 and separated by a distance equal to their length" per Sidney W. Dunkle "Dragonflies through Binoculars" Back to Top |
