THE LIFE AQUATIC

Water veneers aren’t the only underwater moths.

Worldwide, a few hundred species of moth are known to spend their lives below the water surface, at least at the caterpillar stage. Several occur in Britain, including three chinamark moths,

but the water veneer is probably the most sub-aqua species in this country. In North America, the water veneer has been introduced as a biological control agent. Its mission is to help stop the spread of invasive non-native plants such as the water milfoil.
