Goldrenrod Galls – Sept 17 2008

Here are good examples of insect galls on goldenrod

The top bushy gall is caused by the goldenrod gall gnat which stops further stem growth.

Other galls are the spherical bulges lower on the stem of the plant called goldenrod ball galls.  Created by the gall fly larva, these homes are invaded by birds in the winter like chickadees and downy woodpeckers.  It’s even possible to identify which type of bird ate which larva by the hole that is left on the gall.  These larva are also invaded by ice fisherman who use the larva as bait.

The goldenrod gall moth also produces a gall that is elliptical in shape.  Here’s a how it avoids freezing to death in the winter.

Goldenrod seems to have a difficult life.

If you’re interested in more information I’d suggest “The book of Field and Roadside” by John Eastman.  It’s an excellent resource concerning plants and there common insect associates.

Jewelweed by Fen – Sept 2 2008

Jewelweed is a great plant because it is beautiful to look at, it’s exploding seeds can entertain the kids(and who am I kidding adults too), and its stems can be crushed and the juice applied to skin for anti-itch medicine. Pretty cool!

 

Here are two fully ripe jewelweed seedpods.  If you look the the top of the pod on the right you’ll see two small aphids.  I imagine they went flying we I exploded the seedpods.  I didn’t know they were there unil I looked at this photo.

And here are the seedpods after they have been touched.

Insects under aquatic plants – July 22 2008

As I am leading a canoe trip from round lake to long lake I see these insects under a leaf. I assume that they hatched from the egg casings seen on the leaf but I don’t know that for sure. At first I glance they look like spiders.
