Aeshna umbrosa
Dark darner dragonfly with narrow, straight lateral thoracic stripes, some with posterior 'flags' at upper end; frontal stripes usually narrow but present. Abdominal spots small. Pale spots under abdomen. Brown, greenish, blue. Female is polymorphic.
Lakes, ponds, marshes and slow streams. More common on streams than other mosaic darners.
This female was ovipositing on a mossy rock on my koi pond waterfall. The eggs overwintered.

You are welcome. I love learning new facts about dragonflies.
Thank you gatorfellows, that was a really informative page on the Shadow darner. I thought the exact thing Fyn Kynd, when I saw her ovipositing that late. But I researched it and found that it's normal.
"When the eggs are deposited at the end of the season in a cold climate, they enter diapause to survive the winter until they can hatch the following spring. Otherwise, the eggs generally hatch between 5 days and 2 months after oviposition, depending on the water temperature." More at: http://animaldiversity.ummz.umich.edu/ac...
Isn't that a little late for A. umbrosa to be ovipositing?
Thank you Gerardo.
Wow wonderful series :)
