Green caterpillars on beans
 

The Wife (TM) has been finding green caterpillars munching on the leaves of her
beans. Can anyone identify what this caterpillar was, just before She whacked
it? It was about 1/2 inch long. Is there a Weapon of Mass Destruction that
will kill any that are still lurking? We are in Eastern Ontario. Here is a URL
where you may see the beast:

Larval forms of insects. "worms" ;caterpillars"etc can be controlled by
applying a spray of BT--a biological pesticide derivered from a bacterium.

Green caterpillars on beans
 

It look to me like the larvae of the black swallowtail butterfly:

although they are usually found on dill and parsley. I am always pleased to
spot these, and gladly sacrifice a bit of vegetation to help propagate the
species. They are seldom present in large numbers, and do little damage in
the overall scheme of things. Butterfly numbers in general are declining
due to indiscriminate pesticide use, so I try to do my part in creating
mini-ecosystems for the adults and the larvae.

Actually, I'm jealous...I haven't seen any of these guys yet this year,
probably due to last year's drought and this year's cold wet spring, and I
miss them. The only visitors I have to my butterfly bushes are the
ubiquitous cabbage whites.

Cheers,
Sue

Hey, that worm has relatives in my garden eating my tender cabbage
plants. I garden to the West of Ottawa near the village of Barry's Bay. It
looks like the larval stage of the white cabbage moth. What a rotten pest. I
use BT powder. Ritchie Feed and Seed has BT. Good luck
