Walking with some botanically minded friends up Clay Ridge in Remutaka Forest Park, meant that there were three of us with sharp eyes. One of us spotted these sundew plants. So we stopped to take a closer look. It helped to have a magnifying glass and lens.

Sundews are tiny plants with a dark secret. They glisten with a sticky substance and are covered in tiny spikes or tentacles, all the better to catch flies which they trap and then 'eat'.

Of course you don't need to go hiking to find a carnivorous plant, you can buy Venus Fly Trap plants from most garden centres. They are popular presents for children. But I wonder how many children (and adults) know we have these plants in New Zealand too.

This the sundew looks like without the magnifying lens.

Sundews use insects for food because they usually live in poor soil. The ones we saw on Clay Ridge were growing in clay, which doesn't have much in the way of nutrients.
Some other sundews I've seen were in alpine or sub-alpine zones.

I saw this one in the Tararua Ranges near Jumbo Hut

Many thanks to my fellow hikers for their observation skills and great photos.
