Guess we should have clarified that these things are not ‘on’ the leaves but are growing out of them. That’s what happens when something gets into the leaf tissue and the leaf doesn’t like it. This might be an insect laying an egg or a fungus spore getting into a wound. The tree cells rally and create a ‘gall’ around the invader. Different plants create different galls, the most famous and noticeable being the Oak Apple Gall. (Squirrel kits have to learn that those are not food, since they grow where we expect acorns!)
We had to write back to our reader to learn what kind of a tree this was…by the way, thank you to Jeanine for allowing us to use her photos for today’s mystery!
The tree looks like a type of wild cherry, but we’re not sure which.
So with that information, we were able to narrow our search and came up with spindle galls. Viette’s Views gardening blog has an excellent photo essay on galls which includes notes on spindle galls, caused by microscopic mites called eriophyid mites.
Ok, that sound like a bug you can’t stop, and the tree is dealing with it the best it can!
Beautiful mystery, aren’t they? We grabbed these photos before the Hawthorn tree leafed out so the thorns stood out.
Also called the thornapple, hawberry and May-tree, because of course it blooms in May–right now!
The bees are abuzz over it, fighting many other insects for the pleasure. We squirrels will stand clear until fall–then we can’t resist the little ‘pomes,’ the fruit, the hawthorn grows–and then we will be fighting the cardinals and cedar waxwings!
Humans have long noticed this tree, of which some species stay shrubby. The blossoms are thought to bring fortune, and for the Greeks, hope. They carried flowering branches in their wedding precessions. But our wildly variable weather here in Virginia this year makes this Scottish saying true: “Ne’er cast a cloot til Mey’s oot.” Never shed your clothes before the May flowers (Hawthorn!) have bloomed.
This plant has a symmetry thing going on. (The closer one, not the one in the background–the mystery from a week ago!) Any idea what it is?
I’ll check back for your answers later.
This five-leaved plant is a new tree–a Willow Oak. This one has just sprouted after we squirrels planted one of a neighboring tree’s acorns. Later, the leaves won’t be radiation out from one point, but will look like this.
Beautiful, isn’t it? We feature this beautiful member of the swallowtail butterfly group each year because in a week of hard-to-find nature letters, it’s a staple. But it’s also harder to find this butterfly. Its caterpillars eat only one food, the leaves of the Common Paw Paw, Asimina triloba.
This understory tree lives with its roots in wet soil, along streams and rivers.
At least those leaves are huge–10 to 12 inches long and 4-6 inches wide at the middle.
The dark red flowers bloom in the spring and turn into a fruit lumpy with large seeds in the fall. Maybe you can find a tree with caterpillars feeding on it this year.
We’ve had a great time posting this year’s Blogging From A to Z Challenge! Thanks to our many readers for joining us for a look at nature in suburbia. We hope it helps you to enjoy nature around your home!
The rain is taking down all our leaves–but we squirrels are very glad to have it! A wet woods seems to be a safe woods. Here’s a look at the last of our fall color–the red oak trees!- on the golf course from an explore Hickory and I took a few days ago.
Isn’t that a gorgeous tree! It’s an oak, and common, maybe more so than you humans realize.
Chestnut Oak, Quercus prinus, is easily identified by its large rounded teeth along the margins of the leaves and growing in the higher, drier soils. The acorns are bigger than most oaks, and oval in shape.
And speaking of acorns… We squirrels are having a plentiful year, but as always, it’s a tiring chore preparing for winter. A regular reader asked if we’d be taking our winter hiatus again, and the answer is yes. We have some catching up to do. Nutmeg and I need to pick when, but it’ll be soon.
