I had a terrible time with the insects attacking my squash plants this past year so I started looking to see who the culprits were that did all the damage. To my surprise, the mexican bean beetle larvae was one of the problems. They left my beans alone however and just went after the squash and cucumbers.
The website is from the University of Rhode Island:

And just so you'll know, when the squash are no longer available, they will attack roses. I'm battling those little b@$%@^ds constantly. They are a horrible problem here. Look on the undersides of leaves for clusters of their eggs. Grrr.
Nasty lil' buggers!
On the link above, under the individual insects, the eggs are described as well. I picked off eggs galore but it never seemed to be enough! It states: "Females may deposit an egg-mass every two to three days."
It is getting hard to tell friend from foe. Look like lady bugs to me. I wonder if I have MBB's around here.

We have alot of Asian Ladybugs around here. They come into the house in the fall and cluster together in the corners of the ceiling. I get the vacuum out then!
This past year I actually saw some 'true' ladybugs in the garden; they are red with black spots instead of the orange with black spots.
