Tiny things #4

I think this is the final of my "tiny things" posts, but it's a subject that I could probably spend a week on itself: the water in my pond.


More specifically, what's in the pond water. I've been wanting to get the microscope out and take a look for a while, and finally made it happen yesterday.

Aphids and more aphids

It's that time of year again when anybody overwintering outdoor plants inside starts having problems with various insect pests. The critters are there from the start, but it takes a little while for their populations to explode, which is when they first get noticed -- at least by me. In this case, I've got aphids on a couple of small potted bamboos.


Aphids normally won't do too much harm to bamboo and don't seem to like the mature leaves, but these are concentrating on the new, not-yet-unrolled leaves. The choicest, most tender parts of the plant (of course).

Mites on bamboo, or bamboo mites?

If you grow houseplants, chances are you've seen the plant pest called "mites" at one time or another. Mites are tiny sucking insects that mainly live on the undersides of leaves, feeding on the juices of the plant. Unless there's a very heavy infestation, they typically don't cause too much harm, but their feeding results in light "speckles" or "spots" on the leaves from where they've removed the chlorophyll. Many species also create webs on the plants, which is why they are often called "spider mites".


For temperate bamboo growers, mites are one of the most troublesome pests. Although bamboo can host "regular" spider mites, there are certain species of mites that attack mainly bamboo (and closely related) plants: these are called "bamboo mites".
