It was a beetle day. Another pesky one and a favorite. The red milkweed beetles are a favorite because they give great shots that are funny (to me). The imported willow leaf beetle was a surprise: I thought it was an alder flea beetle. All these are in the superfamily Superfamily Chrysomeloidea. That includes the St. John's Wort beetle, also. It must be that time of year. Aphids are thriving. St. John's Wort beetles are happily munching. It was a good morning. I really want to take a course on taxonomy nomenclature. I don't know where yet, but I'll find something.

Still no syrphids! Did the new colony of tree swallows eat them all up? Eat everything up? Bugs are very difficult to find this season.

But I did find 5 this morning. Perfect weather after rain at dawn. Two spiders, two native bees, and that St. Johnswort beetle. Those beetles, of which I found several today on one Rudbeckia plant had their noses into the stem. Whether they were piercing the stem, I could not tell. But there was one who seemed to have another insect with it, as if it was eating it. A bee? Even close examination on the computer failed to solve the mystery. I don't even know yet if they are omnivorous. I did get one to crawl about on my hand.

A masked bee! One of my favorites, if only because of the name and the eyes. A beautiful green bee, also.

The camera is ready to go out for repairs. This is going to be the biennial Rudbeckia year. Poor Lucy was bloodied by deer flies. And I have a tiny little tomato growing on my one and only plant.

Update: I have been reading about Chrysolina hyperici. Information is difficult to find. It isn't in any of my beetle guide books. But Canada and UK sites have some. They are not omnivorous but apparently they don't stick to St. John's Wort, either. I found them on Leucanthemum vulgare and Rudbeckia hirta. What looked like a bee (at least to me with poor eyes) seems to be aphids! That requires further investigation tomorrow. Are C. hyperici attracted to honey dew also? They were imported from Australia in 1943. Australia got them from Europe. They are used to eradicate St. John's Wort, which is a pesky invasive in the west of the US.

By 10:30 this morning, the temperature was already 74°, so the beautiful syrphid flies were gone. I seem to have found a St. Johnswort beetle today: Chrysolina hyperici. My first one. I thought I had photographed the head, but was mistaken.

The aphids are flourishing. I could find no change from yesterday to today except for a population increase. Do the aphids congregate naturally or do ants herd them together? But I'm wrong, there is a change: the ants are different. There are a mix of sizes, smaller with larger now now. Usually they are all large and now there are many small ones.

The flash on the SX50 won't shoot, so now I am even more limited in shots. I have to get the SX70 off for repairs.
