SUNDAY 21 JULY 2013

BUGS II DONABATE

LEADERs: DECLAN DOOGUE, DEIRDRE HARDIMAN, DAVID NASH

This was one of the few days in July when the sky was completely overcast, although the temperature was relatively high, and insects were relatively quiesecent.  It was noticeable that trees such as alder and birch, which are often associated with wetter areas, were beginning to shed their leaves as a response to the drought conditions.

Adult ladybirds seen included the 7-spot, 10-spot, 14-spot and 22-spot.  Most eggs had hatched and pupae of 7-spot were in evidence on a variety of substrates including grasses and cinquefoil and 7-spot and 14-spot larvae were also seen.

Early instar shieldbugs nymphs were plentiful on birch and an occasional one on alder. Empty shieldbug egg cases had been previously found on a willow and some of the alder had been heavily infested by sawfly larvae and similarly a different species was hard at work on a willow.

Sweeping showed the great variety of insects present in the reserve including spiders, harvestwomen, weevils, capside bugs, click beetles, soldier beetles and other groups which were not determined at the time.

Butterflies on the wing included meadow brown, ringlets speckled wood and small white. The latter were populating the field where a ‘bird-mix’ of exotic seeds had been shown. With a little bit of rain there should be a large caterpillar progeny of small whites.

Docks (rumex species) were of interested with the putative hybrids between Rumex sanguineus wood dock, R. obtusifolius broad-leaved dock and R. crispus curled dock
