Blue Butterflies


31 August 2005
There were seven Little Egrets between the Footbridge and the Norfolk Bridge on the River Adur estuary on a low neap tide. Six of the Little Egrets were resting under the warm sun whilst a further Little Egret was patrolling the shallow rock pools left by the receding tide. 

30 August 2005
A clear blue sky without as much as a single white fluffy cirrus cloud and the day got warmer and by the late afternoon the shade air temperature was 26.3 ºC.
Twelve different butterflies fluttered in hardly a breeze, and a few birds seemed to be on the move, but that was it.

Large equinoctial spring 6.6 metre tides coincided with the autumnal weather, in this case warm rain, the temperatures attaining 20 ºC with a 95% humidity, and throughout the day the temperature exceeded 18 ºC with a minimum 91% humidity. 
Rain was steady in the early morning at 7.37 mm. These are exceptional conditions, as rarely is the high humidity combined with warm temperatures.

Adonis Blue Butterfly (second brood)As the spring equinoctial tide receded in the early evening past the Chart Datum point on Kingston Buci beach, a very small first year Tompot Blenny, Parablennius gattorugine, was caught in the prawn net. This are just occasional catch between the tides, occurring about once every two years or one in every thirty rockpooling trips. 
On the lower slopes of Mill Hill, the second brood Adonis Blue Butterflies were confirmed for the first time this year.

The first Wasp Spider, Argiope bruennichi, seen this year was a smallish one that had captured a Meadow Grasshopper on the Slonk Hill Cutting and had rolled it up in its webbing.

Autumn Gentian16 August 2005
I counted up to 200 Chalkhill Blue Butterflies on the lower slopes of Mill Hill before I gave up counting. The total for the day actually seen was about 250 (middle and upper slopes 30, Pixie Path/Mill Hill Cutting SW 20). There were about 20% females and again some of these may have been missed. These numbers are fairly good for the middle of August when the numbers of Chalkhill Blues can fall off a bit. The most numerous butterflies were Common Blues with 300+.
Autumn Gentian (=Felwort) was noticed in flower on Mill Hill and nearby.

It is harvest time at Old Erringham and everywhere on the South Downs 

15 August 2005
Making a quick count scanning with my binoculars, there were at least eighty Mute Swans on the Adur estuary between the A27 Flyover and the Railway Viaduct excluding the two families with four cygnets each known to be resident on the
River Adur and seen by another watcher earlier in the day by Coronation Green. The tide was a mid-to-low neap at 3 metres at 4:00 pm

Wheatear12 August 2005
The unmistakable white rump of the Wheatear was just confirmation of at least three birds by Widewater about to embark on their long migration south for the winter. 

11 August 2005
About 150 of 300+ Common Blue Butterflies seen in less than an hour were attracted to a pool of mud and water near Mossy Bottom Barn on the downs north of Shoreham. The downs were dry and parched. An Emperor Dragonfly flew over the New Erringham Farm fields.

9 August 2005
On Lancing Ring I recorded two butterflies for two personal firsts for that area: the Small Blue and the Small Heath. I also discovered a patch of Horseshoe Vetch with 25+ Chalkhill Blue Butterflies.

The first local hoverfly record of Volucella inanis was discovered in McIntyres Field, near Lancing Ring

Report by Ray Hamblett (Lancing Nature

Subsequently, a specimen of Volucella inanis was identified from New Monks Farm seen on 1 August 2005. This hoverfly was seen on the same umbellifer as Volucella zonaria.

Two Migrant Hawkers (dragonflies) patrolled over at the extreme southern end of the Coastal Link Cyclepath in the town of Shoreham-by-Sea. These were the first two of the year. 
There were congregation of over a hundred House Martins near Lancing College chapel. It appears they are this year's young birds almost ready to leave on their southerly migration.
Adur Levels 2005

7 August 2005
The Salterns at Upper Beeding (near Bramber) is a medieval antiquity site close to the River Adur. From there we walked a little way along one of the side streams that hold far more interest than the barren banks of the tidal river.
Butterflies seen included about 30 Gatekeeper, 2 Red Admiral, 10 Meadow Brown and single Small Tortoiseshell. Close the stream a large damselfly with very dark wings flew out of sight behind a brick building. I took this to be the Banded Demoiselle; Calopteryx splendens. Other blue damselflies were commonly seen at a distance beyond identification range.

The highlight was as male Emperor Dragonfly came over the stream and settled on to the grass within range of a photo opportunity.

Adur Levels 2005

Common Blue Butterflies were out in large numbers in the meadows on Mill Hill. In their most prevalent, there was at least one every square metre, and I have estimated them at a level of about one every five square metres over an area of three acres giving an estimated population of 2400. About one in twenty was a Chalkhill Blue
Sixteen different species of butterflies in a single day is one short of the best ever.

The first Hummingbird Hawk-moth, Macroglossum stellatarum, of the year landed in a Shoreham garden.

A beetle larva of Drilus flavescens was seen on the path in the north-west of Mill Hill.

Fleabane and Common Toadflax was noted in flower on wasteland. The first Autumn Gentian was spotted just coming into flower on the road embankment of the Mill Hill Cutting near the Pixie Path (south side of the A27). Musk Mallow was recorded in flower in a field on the Adur Levels.

3 & 15 August 2005
The mirid bug Deraeocoris ruber is confirmed in my south Lancing garden (TQ 185 046).

3 August 2005
I made a quick 30 minutes visit to Mill Hill for the specific purpose of counting the Chalkhill Blues on the lower slopes: the half-transect (400 metres) count came to 143 (compared to 229 yesterday) including three females. I did not go to the upper slopes but returned via the path above the ridge where 33 further Chalkhill Blues giving a total of 176 for the trek. A surprise was almost immediate sighting of a second brood Dingy Skipper (butterfly), only the second second brood I have ever recorded.

Male Chalkhill Blue

2 August 2005
Chalkhill Blue Butterflies came out with the sun on Mill Hill, mostly on the lower slopes. The count of 268 was disappointing for their peak period. They still represented 40% of the butterflies of seventeen species seen on the day. Seventeen is the most species seen in a single day this year, and only one short of my best ever day species total of eighteen. 
Butterfly List for the Day
Volucella zonaria 1 August 2005
In the damp shade of the Elm Corridor on New Monks Farm (Lancing), flying insects included the predatory Southern Hawker Dragonfly and at least six species of hoverflies, including the spectacular Volucella zonaria, Volucella inanis and the black and yellow Chrysotoxum bicinctum.
