The insect life at Tireragan is varied and numerous and provides a vital prey resource for many other species such as slowworm, stonechats, wheatears and ravens.
The variety observed in insect communities between habitats in Tireragan are an important indication of the health and changes those habitats are undergoing as regeneration continues. The areas of drier sand blown habitat behind the beaches, the leaf compost richer soils inside the mature woodlands, wet bog and drier heath all exhibit unique insect communities, some of which may be of national importance.
Since 2000 the insect communities inside the woodlands have been studied by students from Manchester Metropolitan University which has not only provided baseline data of the insect community but which should also show the changes in insect abundance and variety resulting from the changes in grazing pressure.
