Regular Mooney Goes Wild listener Nikola Brady got in touch with us with a query. She regularly walks her dog along a country route close to her house in Kilcock, Co. Kildare and recently noticed a problem with the Horse Chestnut trees lining those back roads. The leaves of many of the trees that they pass seem to have shrivelled up, and Nikola was concerned that they might be dying. She sent in some photos and asked whether we could identify the problem and suggest what might be done to help the trees.
Suitably intrigued, we dispatched our roving reporter Terry Flanagan to Co. Kildare to meet up with Nikola and to have a look at the trees. As he tells us in his report for tonight’s programme, the culprits are the caterpillars of a moth called the Horse-chestnut Leaf Miner – just the size of a grain of rice and only discovered to science as recently as 1984 – which burrow into the leaves and eat them from within, causing the damage.
This arboreal affliction first reared its head in Ireland in 2013 and appears to be spreading across the country. Happily, although the damage caused by the caterpillar looks severe, it does not result in the deaths of the infected trees, generally coming too late in the growing season to prove fatal.
