Stop 4 on the NUI Galway Biodiversity trail are the herb beds outside Moffats Café. Laura O'Connor (Buildings and Estates) discusses the usefulness of herbs in providing food for humans, but also food for insects such as bees and butterflies, while Dr Dara Stanley (Botany and Plant Science) talks about how plants have evolved to attract insects. A map of the trail (although not necessary to complete the audio trail) can be found at http://www.nuigalway.ie/biodiversitytrail/
