If you head along the causeway from the visitor centre toward the quarry but turn left before descending the uneven rock cut steps, you will find yourself on the edge of Coastguard Lane Field. There is a very stunted, scrubby little oak by the path that goes unnoticed most of the time, but a very close look into its unfurling leaves has found a new species for the Country Park. Holarcticesa clinius (formerly Grahamis clinius) is a parasitic wasp of the family Eulophidae and subfamily Entedontinae, and is approximately 1.5mm long.
