We speak to Chris Bentley, Warden of Rye Harbour Nature Reserve, about his love of moths

What is it you like about moths?

They are fascinating. There's a huge variety of size and colour, and I particularly like moths that pretend to be other things, such as sticks, bark, a dead leaf or a different kind of creature altogether - such as this Hornet Moth. Mimicry is a successful strategy to protect yourself from predators and the Hornet Moth is a fantastic mimic. The moth is as large as a hornet and even replicates the hornet’s jerky flight when disturbed. We were really pleased to see that this one was recently sighted near Peasmarsh, when it had been thought they were extinct in Sussex - only having been recorded twice since 1905.

Then there's the colourful Elephant Hawk-moth, so named that because the caterpillar looks a little like an elephant's trunk, and pretends to be a snake! The foodplants it likes are Bedstraws, Willowherbs, Fuchsias, and Gooseberry, but the adults live only on nectar.

Others, such as this Eyed Hawk-moth have eyes on their wings, to flash at birds to frighten away predators. It has a wingspan of 75mm and an amazing 'face', as you can see, that resembles a cat. Eyed Hawk caterpillars feed on Willow, Poplar or apple trees, but as an adult it doesn't feed at all.

You have a lot of species of moth at Rye Harbour?

We do, but then the list of rare species here is huge. Many caterpillars feed on grass, which is a good evolutionary path - there are a lot of grasses.

Don't they eat wool?

Very few species do that. Most feed on vegetation, including Brambles and Dandelions, although one species, the Satellite Moth, is a partial carnivore, that feeds on other caterpillars. 

How long do moths live?

Adult moths generally only live a few weeks, but can be caterpillars for several months before this, particularly if they overwinter in this stage, and some even several years.

What do moths need to thrive?

They need the right food and enough of it. And they need the right weather, usually hot and dry. In the south east, it's generally warmer, so we get the species that need that. We are also near to the continent, so we get moths that come over and establish themselves with some species caught in weather systems from southern Europe. If there have been 'eruptions' further south, they have to spread out, so find their way here. 

What's the difference between butterflies and moths? 

There isn't a difference. Some butterflies are more similar to moths than to other butterflies. Butterflies can be more colourful, but not always. All butterflies fly in the day, but so do a lot of moths.
