Fargo, ND (WDAY TV) -- They're pink and white, fuzzy, and taking over local parks. They look like a caterpillar, but think again! Things called galls are developing on trees.

They can come in a number of sizes, shapes, and colors. Galls develop around an insect egg that was laid in the leaf. It works to form a protective barrier around the egg.

Our mild winter and hot, dry summer could affect the amount of galls. And that's not the only effect this weather has had on trees. Leaves are starting to drop early. Plus, acorns are abundant.

Jeff Haberman with the Fargo Park District says, "sometimes if trees are in stressed times, perhaps they will produce more fruit, and that's a response to produce more offspring."

All these warm-weather changes likely won't affect the tree's health long-term.
