Ant Swarm – 8th August

During the Bird Count this morning there was an ant swarm that attracted a flock of over 500 Black-headed Gulls. There were also some Common Terns catching the ants and three Hobbies. Two Curlews stopped briefly on the Slurry Lagoon and a Green Sandpiper was amongst the Lapwings. A Little Egret was on the Large Gravel Pit with some Grey Herons and about twenty Cormorants, before joining the gulls on the Slurry Lagoon. Several Roesel’s Bush Crickets and Long-winged Coneheads were also found. On the Lower Path five Brimstones were found along with Commas, Red Admiral and Peacocks. PS.

Butterfly/Dragonfly Walks – 28th July and 1st August

Both of these walks were quite well attended with six and ten people turning up at each, respectively. Despite the weather being overcast on both occasions the air was warm and the insects showed in sheltered spots. When the sun did briefly shine it warmed up incredibly quickly and insect activity increased.

On the first walk, as I had seen a Southern Hawker on the way to meet the group I took them first along Willow Walk, but unfortunately we did not see it although we did find Gatekeepers, Large Whites and a Speckled Wood. Along the Lower Path we came to grips with Large White, Small White and Green-veined Whites, looking at each species in a book and comparing their markings so that most people soon had no trouble identifying their Whites. There were very few Ringlets and Meadow Browns about but plenty of Gatekeepers. All along the Lower Path there were abundant Common Blue Damselflies and just one or two Blue-tailed Damselflies and, near the ‘Irish Bridge’ we found a Brown Hawker. We walked around the banks and found some Common Blue butterflies and there were dozens of Six-spot Burnet cocoons attached to the wire of the Deep Pit fence. We walked back along the north east side of the Slurry Lagoon and found some Small Skippers and one Essex Skipper and the Long-winged Coneheads were thick in the grass, which gave people a foretaste of the Cricket and Grasshopper walks. We gave the Willow Walk and Southern Hawker another try before finishing and the dragonfly was obliging, giving prolonged close views as it patrolled its patch.

The Sunday walk was slightly more successful as the sun came out more and there was more butterfly activity. On the Lower Path we were surprised to see a Weasel that was hunting along the path and coming towards us. It kept darting off the path to one side or the other and reappearing again. As the morning warmed up more butterflies emerged and a splendid Red Admiral was seen, followed by several Peacocks and Commas. This time the ‘Irish Bridge’ gave up a Migrant Hawker and three Brown Hawkers were seen as we followed the path. Several times we were distracted by the numbers and variety of the hoverflies along this walk especially when one or two exceptionally large species were seen. Near the river two Small Tortoiseshells were feeding on the Creeping Thistle flowers. As it was fairly warm we went to the Small Gravel Pit to see what activity there was and found several damselflies emerging from their larval skins and clinging to the reeds. Other Common Blue Damselflies were egg laying, some females going right under the water to lay on vegetation. A Black-tailed Skimmer landed on the beach in front of us as we watched the emerging damselfly nymphs and one or two Blue-tailed Damselflies were also seen. We walked back around the Deep Pit and there were a lot more Common Blue butterflies about than on the previous walk and we finished the walk looking at the Long-winged Coneheads again.

Wood Sandpiper – 14th July

A Wood Sandpiper was seen briefly this afternoon on the Slurry Lagoon, a Redshank and a Yellow-legged Gull were also present. At the north end of the Slurry Lagoon there was an Essex Skipper along with three male and one female Long-winged Coneheads.

Later in the afternoon an adult Mediterranean Gull, three juvenile Little Ringed Plovers and two Shoveler visited the Slurry Lagoon. RW.

Butterfly Walk 23rd August 2009

A very warm and sunny day slightly spoilt by a strong south westerly breeze which kept the butterflies from flying. A group of seven of us set off along the Ouse Dyke where we encountered the usual selection of large, small and green-veined whites, speckled wood butterflies along with common darter, brown hawker and southern hawker dragonflies. We were even greeted by the call of the resident kingfisher as it speed off up the path.

On entering the site we soon found the first of our target species of common blue, which it became apparent are very abundant all around the site as there is plenty of birds-foot trefoil on the bank tops and sides. The next of our target species for the day was the small copper, only one of these was located at the top of a bank I know from previous visits to be one of the best places to find them. Unfortunately we weren’t so lucky with the small heath which failed to show at all, probably due to the wind whipping across the site.

Dropping down to the river bank to get some shelter from the wind we encountered our next target, brown argus. Or at least the back markers did, by the time the rest of us had backtracked it had disappeared into the long grass. However, we did all get to see this small butterfly later as altogether we encountered six in various parts of the lagoons.

The walk continued in the shelter of the hedge bordering the back of the gravel pits where plenty of common blue damselflies along with other butterflies and dragonflies were taking advantage of the windbreak offered by the hedge. Our return to the site found more brown argus on the central bund between the deep pit and the slurry lagoon, and also along the bottom pathe following the railway line.

By the end of the walk we had encountered ten butterfly species, including those mentioned above along with small tortoiseshell, brimstone, meadow brown and painted lady. Other highlights included two hobby, wheatear, whinchat and various warblers.
