Weeks and weeks ago, when it first got cold, Rosie found this funny looking caterpillar curled up on a leaf and wanted to save it. Since then she's found more of them, and is so curious about what they are and what they will be.
The other day when I was outside with her, she found another one of these, now hibernating creatures, and wanted to examine it closely. I'm curious as well, what it is, and what it will be. I think we will find out together.
UPDATE: Thanks to Rosie's curiosity, I found out what this insect will be. The fuzzy thing you see is called a "gall" and it this one was made on a the underside of a leaf from our Post Oak tree, by a cynipid gall wasp.
There are as many species of these wasps as there are species of trees, they infect oak, willow, and many evergreen trees. Sometimes they form one or two of these galls on the underside of the leaf and other times you will see many on one leaf. The galls these wasps make can look very different, depending on their species and the type of tree they are attacking.
The best protection against these insects is keeping your trees healthy by making sure they get enough water, give them vitamins and protective feed and other general care. These insects have increased in their damage over the past several years due to drought and other out-of-the-ordinary weather patterns. This is a native species of insect, and increases in strength when trees become weakened over the stress of severe weather, both wet and dry.
If you see these insects after they hatch they can form a large nest and begin feeding on the tree. This should be cut out of the tree and burned, so as to not infect other trees in the area.
Rosie says she doesn't want to kill these insects, but just wants to make them want to go someplace else to live, since their galls are so pretty. I'm fine with that - not letting them live here. Now if I can figure out which trees need to be treated so that these insects won't thrive after they all hatch. That will be the challenge.
