Euphorbia- Malpighiales- Fabids- Rosids
Not a dandelion but similar looking flower on a long, branched multi-flower stem
These grow rather low to the ground. No idea what it is.
Signs of autumn: a walking stick insect. I'm pretty sure this is a Northern Walkingstick, Diapheromera fermorata. Such a dopey insect. You can tell it's a herbivore.
