This is the trail left behind in a trembling aspen leaf by the feeding of a leaf mining insect larvae. Nearby leaves similarly affected contained small, yellow larvae, likely caterpillars of the Common Aspen Leaf Miner (Phyllocnistis populiella).
'Pretoria' Canna is an annual plant in cold weather regions and is a perennial plant in warm weather regions. This is one of at least two distinctly different clones that is sold under the name 'Pretoria' Canna. Annual or perennial, this clone of 'Pretoria' is big and bold! Sam Bahr, photographer
A leaf gall is an unusual growth of plant’s cells on leaves. The galls are usually formed on the younger leaves and galls develop into the leaves as they grow. They appear to be green lumps and then later in the season the will turn brown or red. The galls are oval and can grow to 6-mm long. There may be only one or several galls on a single twig or leaf. In general, the leaf galls do not cause serious problems to the plant.
The cause of leaf gall is usually a sawfly, a type of primitive wasp. As the tree leaves are expanding the adult sawflies insert the eggs into the expanding tissues from April to June. A single female is able to lay up to 50 eggs. This is what causes the leaf to swell into a lump or chamber, which nourishes and protects the developing grub. Most of them emerge by fall and over winter in a cocoon in the leaf litter on the surrounding ground. There is only one generation per year.

I'm guessing that this is a Japanese Maple leaf. Found near the entrance to the Valdosta Country Club Grill when Jim took me to lunch during my spring break. He was feeling better, and I had gotten a sinus infection. :(
I always "encourage" spiders to live in my plants as pest control. this one has been here for a few days.
I'm still learning how to make the moving pictures. Walked in the woods yesterday. Watching the rain today. Mmm... fall. :)
Another Coelioxys nest parasite bee from the Adirondack Mountains of New York. This one is a nest parasite of big Leaf Cutters like Megachile latimanus. Here are shots of a male and a female. You can see the long pointed abdomen that the female uses to cut into the nest walls and the odd multipronged rear ends of the males, the uses of which are not apparent to me...but all the Coelioxys males have them.
