Stop, start insect migration

Another hot sunny day. A light east breeze till 10:00 then 30 minutes NW breeze, before switching back to SE.

These shots by Janet from the Nature Park yesterday

Emperor on the pond along the dog walk path

Immature Moorhen on the same pond. There has been three chick broods

Sandwich Tern on beach 


South shore - Malcolm 09:15 - 10:30
Pied Wagtail 4

One of three foreshore Wheatears, the other was along the sea wall

Whimbrel 1
Whimbrel on the edge of Red Nab
Redshank 55 near wooden jetty
Turnstone 4
No Mediterranean gulls seen. 
This blue ringed juvenile Black-Headed gull was on No.1 outfall
Ringed at Martin Mere 16/06/25 - this is its first sighting 

Even at 09:30 there was a steady flow of butterflies coming in off the sea.
Red Admiral 8
Small Tortoiseshell 4
Small White 1
But by the time I reached the end of the wall at 10:00, the breeze had switched completely, and suddenly, to the NW, and incoming butterflies on the way back were just the odd Red Admiral, which could have come from the scrub near the lighthouse.
There were still lots of butterflies in the Nature Park
Red Admiral 15
Small Tortoiseshell 10
Small White 3
Large White 1
Speckled Wood 3
Migrant Hawker 1

A second check from 14:30 - 15:45.
Mediterranean gull 2 - an adult between the outfalls and a juvenile flying along the sea wall.

I was expecting quite a lot of insects to be moving through, but that wasn't the case. Possibly as there was more south in the breeze or perhaps it is just that they have to arrive from somewhere, and leave at some point. It can't be a perpetual conveyor belt of insects.
These were seen to come in/off along the sea wall
Red Admiral 5
Peacock 1
Painted Lady 1
Meadow Brown 1
Small White 1
There were several Red Admirals and Meadow Browns on the scrub near the lighthouse. Also Small Whites 5. Painted Lady 2
Painted Lady

There were small black flies everywhere, particularly towards the end of the sea wall. Most will be locally bred kelp flies. This is an example of the density here, you have to try to not breathe!

Not all the flies were home grown, there were some larger ones as well.
This one has a great name! red-thighed St Mark's fly

In the Nature Park
Similar to this morning, but more Meadow Browns and Common Blues. Plus: 
Painted Lady at least 1
Clouded Yellow 1 female flew past me heading towards the white barrier. Unfortunately not relocated. She was moving quickly with apparent intent, so unlikely to be the same as the one Janet saw yesterday

Just two Cormorants on the main pond today, doing a spot of snorkelling
