I probably wouldn’t have noticed these scale insects were it not for the ants that would occasionally stop to feed from them.
Its difficult to see in the first photo, but each one has 20 or so waxy threads spiraling away from the body. It’s not clear to me where exactly they’re coming from. The threads are a bit easier to see in the next few photos.
I wonder if the spirals don’t help the ants to locate the scale.
The scales excrete honeydew from a small orange tube (to the left above, right below).
Here’s what might be an immature form of these scale insects. The tube where honeydew is excreted is easier to spot here.
And finally, here’s an ant soliciting honeydew from that same small scale.
I’ll separately post more photos of the ants.
Note how they’re arranged along the central leaf vein. They’re undoubtedly taking plant juices through that midvein.
Click on the photo for a larger version and see if you scan spot a small mite (an “easter egg” I didn’t know about when I took the photo). Then see if you can find its recently cast off skin!
