Here are my latest photos of tiny bugs and the structures they make on the back on leaves.
One leaf I looked at had these very tiny bugs. Probably nymph stages.
And I found more of these structures that I had seen before –
I am inclined to think they are cocoons rather than eggs or lerps.
These do look like eggs –
And I think these are built by scale insects –
And more lerps –
The photo below shows three lerps that range in size. I think the insect that lives under the lerp has discarded the smaller ones as they have grown in size.
In the photo below, you can see a very tiny orange bug. But under the lerp is a much bigger bug just visible.
Its easier to see the resident insect in the photo below –
And in the photo below, you can see two small lerps and what I think is whole made by a bird when it pecks off the lerp and the insect. It eats both.
I think perhaps Scale Insects built these –
On top of the one below, next to the hole, you can see a small bug.
And these are galls –
And on two leaves, I found this structure. I have no idea what it is.
