A couple days ago, Betsy and I visited Butchart Gardens on the way back from our cruise to Alaska.
It's a lovely place, and the weather was perfect. Flowers everywhere, of course.
Many darners were flying over the open grassy lawns, but no other odonates were seen for a while – until we came to the "Star Fountain," shown above. There we saw lots of Tule Bluets, including one that liked to perch on the begonias:
Notice the almost equal-width bands of black and blue on the abdomen, with the black bands actually a bit wider than the blue ones. The Northern and Boreal Bluets differ in having mostly blue on the abdomen, with small black rings separating them.
In addition, we saw a darner fly in and land on one of the "frogs" that shoots out streams of water. Here it is:
It's clear that this is a female, due to its overall brownish and greenish color, and the expanded tip of the abdomen that holds the ovipositor. Females are generally a bit more difficult to identify than males, but in this case the identification was easy. Notice the small "bump" – or tubercle – below segment 1 of the abdomen. Here's a better view of the bump:
The interesting thing about this bump is that it's a distinctive field mark for the female Blue-eyed Darner. None of the other mosaic darners in our area have this bump. It's a good field mark to look for, though it's not always as easily seen as it is in this view.
