Critters 2: … and the ugly!

I came across these cute (and gross) creepy crawlies last Friday. They were all over the kale in the greenhouse. At the time I thought they were caterpillars but I later learned, through a lot of Google image searching, that they are cabbage worms or cabbage loopers. They attack brassica family plants, such as the kale and collard greens that are currently in the garden.

These guys hide in plain site. I almost didn't see them, and then I saw a ton of them!

According to About.com, the worms are the larva of the cabbage white butterfly. As soon as I read this, I remembered chasing a little white butterfly with my camera as he fluttered through the garden not long ago. At the time, of course, I thought it was so cute. Little did I know, their larva are the ultimate ugly.

What’s ugly is the amount of damage these little buggers can create. Unbelievable.

They have teeth!

They’re eating the kale right before my eyes!

I thought about picking them directly off the plants but I couldn’t bring myself to handle their soft, squishy bodies with my bare hands. Stroking their backs was as brave as I could get (they’re furry!).  Seeing their little mouths chomping on the kale was another deterrent from picking them up. I didn’t want to get bitten :).

I came across this interesting post yesterday by Urban Organic Gardener while I was searching for  information about cabbage worms. His post showed that the black spots in my picture below are actually worm poo and not aphids as I’d thought.

I thought this was aphids

That’s a lot of poo, which can only mean — a lot of worms! Nooo!

I managed to pick up a copy of Grow Great Grub and You Grow Girl by Gayla Trail from my local  Hamilton Public Library branch. I remember the books having sections on organic pest control (as most gardening books do) that I had ignored in the past but now I desperately wanted some reliable info on cabbage worms.

Here are just some of the recommendations from the books and entries from Hubpages and Better Homes and Gardens that I came across:

1. Companion planting – with items such as Aster family flowers (which if Wikipedia can be believed includes sunflowers, yarrow, and calendula), onions, and sage that either deter the worms or attract insects that will prey on them. Note that the examples I used are all growing in my garden. The sunflowers and calendula are close by but they aren’t in full bloom yet.

2. Use floating row covers to keep the butterfly from laying its eggs on your brassicas.

3. Handpick the little buggers off of your plants.

First calendula bloom of season.

First calendula bloom of season. Hopefully it will attract some predatory wasps to eat the cabbage worms.

I took home some collard and beet greens last Friday. When I got around to washing them on Sunday, I found two worms had hitched a ride and survived the fridge (well, one was moving in the water; the other wasn’t). A clear reminder to check my leaves carefully before I bag them.
