Early May insects are thriving in the warm sunshine. St Marks Fly Bibio marci and others in the genus Bibio have appeared in numbers, dancing over the Hawthorn and other blossoms. Today at Pebsham there were many Orange-tip butterflies on the wing and a male Brimstone was spotted passing along a stretch of hedgerow. I spent a while trying to record insects along one short stretch. The Red-headed Cardinal Beetle on a sprig of Cow Parsley was noted. The larvae live under the bark of trees but the adult beetles are predatory and hunt insects on flower heads. Also seen was the Bishop’s Mitre Shieldbug the larvae of which feed on unripe grass seeds and the hoverfly Xanthogramma citrofasciatum the larvae of which are associated with aphids in ant nests.
Yesterday during a walk in Alexandra Park the Mirid Bug Harpocera thoracica was seen on a leaf below an Oak, the host tree of this Bug.
Hundreds of cuckoo Nomad bees were patrolling at both places, searching for their Mining bee host nests.
