I have been very satisfied with the hosting service of POWWEB which I have used for these websites for the past 13 years so I recommend it.
In the previous post I indicated I was trying to identify wasps that had taken up residence in mason bee tubes, without actually parasitizing the mason bees
I found the larvae in tubes while removing the mason bee cocoons in the winter, and transferred them to a separate jar where I let them hatch. By May 1 they were hatching so after taking a few pictures, I sent the images off to BugGuide.
The result after several months was an identification by an expert in entomology : Our thanks to Matthias Buck of The Invertebrate Zoology Section, Royal Alberta Museum, Edmonton, Alberta, Canada
So he thinks there are actually three species represented in these pictures.
Kingdom Animalia (Animals)
Phylum Arthropoda (Arthropods)
Subphylum Hexapoda (Hexapods)
Class Insecta (Insects)
Order Hymenoptera (Ants, Bees, Wasps and Sawflies)
No Taxon (Aculeata – Ants, Bees and Stinging Wasps)
Superfamily Vespoidea (Yellowjackets and Hornets, Paper Wasps; Potter, Mason and Pollen Wasps and allies)
Family Vespidae (Yellowjackets and Hornets, Paper Wasps; Potter, Mason and Pollen Wasps)
Subfamily Eumeninae (Potter and Mason Wasps)
Other woodpeckers have been using the suet feeder outside my window this winter but this was the first time I had seen the Pileated woodpecker here. The photo was taken hastily through the salt-sprayed window while at my desk, thus the blur! We often see and hear these woodpeckers in the summer as they like the large old fir and alder trees along the property.
Species: D. pileatus
Dryocopus pileatus (Linnaeus, 1758)
The Blue-eyed Darner Rhionaeschna multicolor showed up in late July. Several buzz the pond continuously on a warm day.

A neighbour told me that Astilbe were good pond plants, so I have tried several. I think they need to be kept on the margins and well fertilized.
Genus: Astilbe spp.
Actually called Giant Dwarf papyrus, this plant is hardy only in zones 9-11 so I move it into the greenhouse in the winter.
In August the bloom of Azolla has started to increase. I added Azolla to the pond several years ago and have in the past had to skim it off as it covers the complete surface in late summer. It does provide good compost material with high Carbon and Nitrogen content. It normally cannot live in Northern climates but somehow has survived well here in the pond.
A good reference can be found at the Azolla Foundation
The Azolla Foundation was set up by Azolla Biosystems Ltd founders Alexandra and Jonathan Bujak to provide a platform for sharing information about Azolla and its contribution to new technologies such as space exploration and planetary colonization.”
Also, the Nitrogen Fixation is the result of a sysmbiotic relationship between azolla and a cyanobacteria. This reference shows the formula for the process:
I have only seen this one female specimen in the pond, and it was clinging to a pondweed leaf, almost submerged in the water, and didn’t object to being placed on the lilypad.
Species: A. junius
Last fall I got this small plant with floating leaves and small yellow flowers. It spreads asexually with stolons near the water surface. It also was winter hardy Zone 8-10 as it overwintered in the pond. This one was supplied to a plant store by a local company here in Victoria, Applied Aquatics.
