My white swan Echinacea are currently plagued with small greenish caterpillars that are living in the flower heads. They spin threads and pull the petals in to cover themselves whilst they eat little furrows across the flower head. When they are exposed and irritated they wriggle furiously and drop off to the ground. Any idea what they are and how to combat them?

This always tears me in two. I really love wildlife and that's why I started my garden but now and again the 'prim and proper gardener' in me wants to have perfect plants with no holes! but I think balance is key, birds will make sure of this beside I think a little damage is okay.
Most butterflies feed on nectar from many flowers but their caterpillars will only feed on very specific food plants and won't eat anything else. And they have declined sharply in the past few years. What I've done is I've researched caterpillar 'food plants' such as nettles and ivy and created an area away from the main flower garden in a sunny corner where they can munch to their hearts content without destroying the effect of the rest of the garden.
Very good point made above 'no caterpillars no butterflies". Maybe relocating them could work :-)
Thanks for this. I suppose I'm just thinking if I destroy the caterpillars then there will be no butterflies!? They certainly do love my nasturtiums, sadly.
The main problem is with the small white butterfly - others (eg small tortoiseshell) live on plants like nettles. Small whites like brassicas and nasturtiums. I plant nasturtiums in the veg plot so that the small whites lay their eggs on them rather than my cabbages. I net all my brassicas - not just against butterflies, but also pidgeons usually demolish them in the winter. Would rather have the pleasure of butterflies in the garden than plants without holes and no butterflies.
Depends whether the attractive plants are food for the adult butterfly (providing nectar) or food for the developing caterpillar (usually leaves)! I don't know of caterpillars that eat ivy or buddleia or lavendar - but the butterflies go for the nectar in the flowers. I don't know what feeds adult cabbage white butterflies, but I know the caterpillars love all brassicas and nasturtiums.
So what are you supposed to do about them? I'm torn between saving my plants and protecting wildlife... If you have plants to attract butterflies, doesn't it follow that you will have caterpillars?!

Hi Katie - I can see you are having problems adding images. Click the icon with the curved arrow called reply to reply to one of these forum posts. A box will open allowing you to type in a message.

Hi Nicola thanks for your reply.I did take a leaf to My garden center they recomended Provado Ultimate Bug Killer but it didnt get rid of them.I have treated them with the bacteria Bacillus and overnight I havnt seen any damage too any leaves so heres hoping.I hold a safe use of pesticide and application certificate for spraying horticultural pesticides etc so can use all legal chemicals and yes it is always changing the legislation and banning of chemicals alot of banned products were very good.I need to properly identify this caterpillar I think it is a moth as the larvae appeared September time , im wondering if it came in with new plants or with disturbing the soil? .. .
Hi Adrian, when it comes to chemical control of pests the list of allowed chemicals is changing all the time. I suggest that you visit your local garden centre to find out what the latest and best solution is. Take your leaf along with you. They will have the most up-to-date information as regulations about permitted chemicals change frequently.
In autumn of 2010 I planted lots of polyanthus plants and Pansies everyone was eaten by caterpillars.Big cuts and holes appeared in the leaves eventually only the ribs were left.I have planted all My summer bedding and there are still caterpillars they have overwintered in the hanging baskets and are now starting too eat Bgonia and Pelargonium leaves , I treated them today with BACILLUS THURINGIENSIS THURICIDE what are the caterpillars will this Bacteria get rid of them?

Hi, Karen, Oops, the photos didn't upload. Are the holes along the margins and look somewhat knotched or scattered throughout the entire leaf? Primiarly along the edges is most likely vine weevil. Caterpillars cause holes scattered all over the leaf. Rhodos are susceptible to both. If caterpillars you can give a thorough inspection and pick them off. If it is vine weevil, it is more serious as you have to kill the larvae in the soil. Is your plant in the ground or in a container? Kathy C
