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.
So he thinks there are actually three species represented in these pictures.
Eumenines prey mainly upon moth larvae, although some take larvae of leaf-feeding beetles.
Adults take nectar.
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) Genus Ancistrocerus
There were three species identified from my photographs( labelled above) although it is very difficult to confirm identity without being able to examine a specimen. Next year I will be sure to send him samples to confirm, and I will certainly not destroy these larvae when cleaning out mason bee tubes.
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.

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.
There is a theory called the “Azolla event ” where it is believed that Azolla in the tropical Arctic 39 million years ago fixed so much Carbon that it reversed global warming. Reference .
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.
For several years now I have been growing a very successful and attractive lily in the pond which I originally bought from a local plant store as a reddish-orange kaffir Lily, Schizostylis coccinea.
The interesting thing is that it reproduces from seeds very well –and last year a pale pink variety came from a seedling. I kept these plants in the same pot and overwintered in the greenhouse. Normally the red flowers appear in August, but when I set it back in the pond in March, after continuing to bloom most of the winter, it flowered again for a month. Then in early June the pink-flowered plant came into bloom and is still flowering in July. All the other “scarlet river lilies” (see political correctness comment below”) that were left in the pond over winter will bloom again in late summer.
A number of interesting points come up when researching this plant:
1. The “pink” variety I have does not correspond to either of the pink varieties mentioned in this reference . “Schizostylis coccinea ‘Mrs Hegarty’ was named by Sir Frederick Moore, the Director of Glasnevin Botanic Garden, after the lady who discovered a chance pink seedling in her garden in County Galway in 1914. She was persuaded to show her plant at the RHS show in London in 1919. It was immediately successful and was given an Award of Merit. Schizostylis coccinea ‘Mrs Hegarty’ has deep rose-pink flowers and yellow anthers and has been rather superceded by the cultivar ‘Sunrise’ which is also pink. Schizostylis coccinea ‘Viscountess Byng’ has pale pink petals and the anthers are purple brown. This cultivar is later flowering and is named after the dedicated rock gardener of the 1920’s. Her flower beds were sometimes temporarily covered in water.”
Reference: “St. Andrews Botanic Garden Flower of the Month”However the anthers of the pink variety I have are pink!
2. A Scientific name change:Schizostylis spp. came to be seen as distinct from Hesperantha spp. whereas in almost every detail, Schizostylis is identical to Hesperantha. Most Hesperantha species have pink flowers, while Schizostylis is bright red. Since forms of Schizostylis with pink flowers are found in cultivation and in the wild, however, that doesn’t seem to count for much. The final proof is that Schizostylis and Hesperantha is the DNA data, which confirms that the two genera cannot be separated.
3. Political Correctness has influenced the common name . For years it was known as the Kaffir Lily. As the Ken Thompson points out in this 2012 Telegraph article:
“–Kaffir is an offensive term for black South Africans. I suspect no one outside South Africa is likely to consider “kaffir lily” a racial slur, but nevertheless I sense a campaign is afoot to find something less offensive. Crimson flag lily, Cape lily and river lily, or scarlet river lily, all appear to be in circulation. ”
The Drakensberg mountains in South Africa are where most of these lilies come from.
