A male Broad-bodied Chaser (dragonfly) flew to and fro over the new pond at Truleigh Hill. It was my first dragonfly of the year.  On the downs near Truleigh Hill there was a fenced in are of a hundred plus Welted Thistles in flower.

A diesel spill in Lancing Business Park drained into Brooklands Lake poisoned the water and resulted in dead fish floating on the surface..

Elderflower had now taken over from Hawthorn as the dominant flower in the hedgerows.

Adonis Blues
Grizzled Skipper

White fluffy Cumulus clouds allowed intermittent sunshine brought frequent butterflies out on the lower slopes of Mill Hill. About three-quarters were lively Adonis Blues (38+7=45+) over the swathes of Horseshoe Vetch, Hippocrepis comosa, frequent Small Heaths (20+), patrolling Brimstone Butterflies (10+), a few Large Whites, a fresh Grizzled Skipper, a fresh Dingy Skipper, a Wall Brown, a very fast flying Peacock Butterfly, at least two each of Burnet Companion Moths, Cinnabar Moths and Treble-bar Moths. Two pairs of Adonis Blues were mating.

A Buzzard flapped its wings and then glided in the clear turquoise blue sky over Anchor Bottom. A minute later a second Buzzard followed the same path in the sky. In the hazy sunshine, I also spotted my first Swallow of 2019 over Erringham Gap and a second on over the Downs Link Cyclepath at Upper Beeding by the South Downs Way Bridge over the River Adur

Adonis Blues

On a sunny afternoon on the lower slopes of Mill Hill produced scores of restless butterflies fluttering around the early swathes of Horseshoe Vetch, Hippocrepis comosa, There were well over a hundred per acre of nine species and all of them were very active and I had to wait for over an hour for any to settle nearby. Dingy Skippers were the most frequent with over forty seen, but Grizzled Skippers were old and much harder to find only a handful including an amorous or sparring pair. The only one that settled for a second was slightly frayed at the edges. Twenty or so male Adonis Blues were very lively until they came across a few females. Small Heaths (12+) were frequently seen often chasing each other and sparring with other species including occasional Common Blues. Brimstone Butterflies patrolled incessantly without pausing, occasionally bumping into the whiter females and both a Large White and a Green-veined White. A flash of grey was a disturbed Treble-bar Moth, and a pretty Mother Shipton Moth was recognised when it settled. A Speckled Wood patrolled the southern steps and a fresh Brown Argus was seen clearly by the winding path, near some Wayfaring Tree shrubs.

Dingy Skipper with Horseshoe Vetch

A flutter of brilliant blue over the lower slopes of Mill Hill heralded the beginning of summer on the downs with the first male Adonis Blue Butterfly of the year. It was unmistakable even though seen in the middle distance for 15 seconds at most; too far away to follow it for a photograph. Under a dark cloudy sky with the first spots of rain, it was too cool for many butterflies. It was only after nearly an hour did I manage to disturb the first of half a dozen Dingy Skippers, followed soon after by a Small Heath, a Green-veined White and a probable Peacock Butterfly. If I had not delayed my return I would missed the Adonis Blue and a probable Wall Brown.
