These orange beetles are common at this time of year and are usually seen in pairs like this.

This plant is 'Cat's-ear' flowering in the crop margin. Only when we looked at the pic on the screen did we spot the 7-spot Ladybird left and down from the centre. The bright yellow splashes of colour against the dark is how it really looks.

Paraphrasing the guide book .. 'eats Ragwort leaves and flowers' is illustrated by this caterpillar inside the decimated flower head

This Cinnabar moth Caterpillar is feeding on it's favourite food plant the poisonous Ragwort.

We didn't realise that Cinnabar Caterpillars could eat ANYTHING but Oxford Ragwort - ID books mention no other food plant - so were surprised to find a few of these striking insects on patches of Groundsel. The mostly decimated plants, with mostly only one caterpillar per plant, shows that Groundsel is a useable but barely adequate plant food for this insect.
This information/advocacy from web site http://www.ragwortfacts.com/cinnabar-moth.html from which we quote:-
The Cinnabar Moth can use many members of the genus Senecio as foodplants but for long term success larger plants that persist for a long time are necessary. Some uninformed people who campaign against ragwort say that groundsel is sufficient as a foodplant. This is not true. While the caterpillars can and do use groundsel the plants are small and unlikely to support large batches of eggs also groundsel is a more ephemeral plant that does not normally persist on sites.

Instead of the normal one or two clumps this year we have a at least 30 single Oxford Ragwort plants spread through the rank grass. This poisonous plant is the food plant of Cinnabar caterpillars which retain the poison to become poisonous themselves. As usual we will attempt to stop these plants making too much seed - Ragwort is very poisonous to cattle who graze near a boarder.

Now we have no livestock in the fields around us, we let (the poisonous) Ragwort flowers grow (but still destroy most of the tops before the seeds form). This has hugely benefited the Cinnabar moths of which these are the Caterpillars.

An unusual excess of Ragwort in our meadow brought with it an unprecedented number of Cinnabar caterpillars. Ragwort is poisonous to some mammals, but it is the only food plant of these caterpillars.

This Cinabar this caterpillar was waving itself about. A knowledgable visitor tells us they tend to do this when they are hosting the larva of a parasitic fly.

And here a view of it in flight providing a view from below. It was not a very cooperative flyer & this was the only one worth showing.

Caught in the Moth trap, but definitely NOT a moth was this Cockchafer, also known as a May Bug (and caught in 29 May!). First a view outdoors before it flew off.

Normally we have only occasionally seen Cockchafer beetles whizz by, but this one was playing dead (and wasn't!) in a shed so we took some pictures before putting it somewhere safe. Its BIG - the body is 3cm long.

We found 4 male Cockchafer beetles in the moth trap, but only this one would fly for us. Beetles have 2-wings (the transparent lobe lower left and right) with the other pair of wings evolved into the protective wing case upper left and right.

We found 4 male Cockchafer beetles in the moth trap, but this is one of those that would not fly for us. We released them all into a bush near the house. According to 'the book' the powdery wing case indicates a recent emergence.

Here the Cockchafer Beetle is creeping over hawthorn foliage, wings neatly hidden and protected under the cases.

This large and heavy insect is a Cockchafer Beetle, also widely known as a May Bug. This one is a male (feathered antennae at the top) lifting the wing cases prior to taking off.

This might be a 'common' bee-fly (one of 12 or 15 species according to which book you look in but neither has any detail) but it is new to us.
