Rice Stem Borer
A small white moth whose larvae bore into rice stems, causing the devastating symptoms known as 'dead heart' in vegetative stage and 'white ear' in reproductive stage. It is one of the most serious pests of rice in Asia.
Did You Know?
A single larva can destroy an entire rice tiller by boring into the stem and feeding on internal tissue from the inside out.
Dark-barred Twin-spot Carpet
A common but variable carpet moth found in gardens and hedgerows. Wing pattern ranges from pale to very dark. Larvae feed on bedstraws and other low plants.

So variable in appearance that dark and light forms were once described as separate species.
