Amazing,
imagine how many there must be to show up like this.

So that's where all the Painted Ladies are

Always a species that varies in numbers year to year in Lithuania, but for the first time ever, I didn't see a Painted Lady in this country this year ...which deprived me of beating my top year list from last year!

Back in 2009 I was sitting in the garden here in France when I noticed a procession of butterflies crossing the garden, it took me a while to catch on that it was painted ladies migrating but the scale was staggering - approximately 10 a minute all day long for two days!! The maths is mind blowing especially when I think about the broad front they were traveling on.

Interestingly they all followed almost exactly the same route across our garden and our neighbours' - following a pheromone scent trail?

Amazing. I've only seen a handful this year in London + the south-east, mostly on my local patch with a maximum daily count of 2!

Interesting. But to be precise, seen on radar, not from space.

I dipped an American Painted Lady on the Lizard once - Kynance Cove - by a few hours. Always been a bit surprised that there are not more European records. Easily overlooked if you do not check the underwing?

All the best
