The earlier pictures were taken on my wee compact Canon ixus 970IS, which involved sneaking up on the butterflies. This can be very frustrating when they fly off, but very rewarding when they don't!
Since 2012 I have been using a Panasonic Lumix FZ150, which allows me to zoom in to the butterflies from a couple of metres away.

Orange Tip - Anthocharis cardamines
Following on from my posts about caterpillars that I had observed through to being butterflies last year, here is the story of some Orange Tips from this year.
Last July I was working on an old railway that is now a walkway and cycle path. I noticed a number of dried up Garlic Mustard seed heads along the edge of the path. I checked the seed heads and managed to spot two Orange Tip chrysalises.
The chrysalises are beautifully camouflaged and look just like a thorn, or part of the seed head.
I realised later that the plants along the edge of the path are cut back each year, so the next time I was there I found three chrysalises on the plants which would have been cut and took them away with me.
The seed heads with the chrysalises attached lived in my garage over the winter, next to the window.
Every couple of weeks I would spray them with water to stop them drying out. I wasn't sure if this was necessary, but my reasoning was that if they were outside they would have been rained on, so I thought it was necessary.
Towards the end of April, I noticed that one of the chrysalises had started to change colour, showing the wing pattern of the butterfly. The other two chrysalises also changed shortly afterwards, revealing that they were all going to be boys!
On 29th April the first butterfly emerged, over nine months since I collected the chrysalis. The next butterfly emerged on 30th April and the third one emerged on 1st May. Although, yet again, I didn't see the butterflies emerge, two of them were waiting for me when I arrived home from work. The top of the container was left unzipped for them, but they appeared to be quite happy just sitting on the side of it.
It was good to know that I had helped three butterflies to survive, that would otherwise have been mashed up by a mower!
I planted a Garlic Mustard plant in a pot in the garden this year and I was delighted to see an egg on it on 19th May. I can't say when it was laid, but it was orange meaning that it was at least a day old.
On the 1st June I noticed a small caterpillar on the plant, which had probably hatched the previous day and today when I was searching for it, I noticed that there are two caterpillars on the plant, each on different flower stems.
And so the cycle continues!!
