26th June - Craigavon Lakes


In June 2006 we had found several hundred Bee Orchids (Ophrys apifera) at this site between the North Balancing Lake and the railway line. This year we found just 2 growing in the shelter of a gorse bush and only because Pamela Thomlinson was photographing a Common Blue butterfly there!  Unlike most orchids, the Bee Orchid produces a rosette of basal leaves in the autumn which is photosynthetically active during the winter. We speculated whether the long harsh winter might have damaged these leaves. However Bee Orchids are notorious for the fluctuation in their numbers at any particular site.

We did find about 50 Common Twayblades (Listera ovata) and hundreds of Common Spotted Orchids (Dactylorhiza fuchsii) in varying sizes and colours from almost pure white to purple.


On a lovely sunny afternoon many Common Blue and Meadow butterflies were in flight as well as red and black Cinnabar and Five-spot Burnet moths.

Purple Knapweed (Centaurea nigra), pink Centaury (Centaurium erythraea), violet Tufted Vetch (Vicia cracca), white Ox-eye Daisies (Leucanthemum vulgare), yellow Meadow Vetchling (Lathyrus pratensis), Birdsfoot Trefoil (Lotus corniculatus) and Mouse-ear Hawkweed (Pilosella officinarum) gave a rich variety of colour to the site.
