Guide to Butterflies in Winter

Download this guide as a PDF

In winter our thoughts don't normally turn to Butterflies, but every species that breeds in Britain are out there in the freezing weather, coping admirably as they have done for millennium.

Each species has a different strategy for surviving; they will be in the form of egg, caterpillar, chrysalis or the adult butterfly.

Adult Butterflies in winter

It is possible to see flying butterflies every day of the year as several species spend the winter in 'hibernation' as adults. If the temperature rises, as it can even in mid January, 'sleeping' butterflies may be stimulated to have a fly round and look for a nectar source. This is disastrous as there are very few. The butterfly will have taken on fuel in autumn to get it through the winter, so flying will reduce its stores. Warm winters are not good for over-wintering-adult butterflies. The bodies of the insects have anti-freeze on board and they all try to hide out of sight!

Red Admiral: These have recently survived mild winters in Britain, but any hint of frost will kill them. The first Red Admirals you see in spring will usually be migrants from the Continent. Overwintering adults in Britain are very late hatchers that wouldn't risk migrating south.

Small Tortoishell: These hide in out-houses or holes in trees. They do come into our homes, - if so, gently pick them up and place outside in a shed, otherwise they will die.

Peacock: These hide just as Small Tortoishell's, but often in groups indicating that they can communicate. If disturbed, they can hiss like a snake and may flash their open wings displaying their ‘eyes' to frighten a mouse or a bird disturbing them.

Comma: These don't use buildings but hide in woods and shrubbery low to the ground. Their wings looking like dead leaves.

Brimstone: Although bright yellow in colour, the wings are shaped like a leaf, they hide in evergreen shrubs like Ivy.

Over wintering as a chrysalis

Our three 'White' Butterflies: Large, Small and Green-veined, sit out the cold as chrysalises. In this stage they are vulnerable as they are relatively large and can't move, so they are camouflaged and hang on tree trunks or shrubs to merge into the back ground. The Orange Tip, spends 11 months as a chrysalis looking like a thorn or spur on a stem. 4/5 won't survive being eaten by predators.

The Speckled Wood, is unique in Britain, it is the only species that overwinters' as either a chrysalis OR a caterpillar, they are hidden in course grasses. There are two emergences to adults; in May and June respectively.

Over wintering as a caterpillar

The Common Blue spends the cold months as a tiny slug-like green caterpillar, hidden on the underneath of the leaves of Bird's-foot-trefoil. We could easily walk on them as we wander around, but enough of them survive to continue to wake up and eat the growing plant. These caterpillars spend 10 months as this form. Meadow Brown's lay their eggs on fine Meadow grasses, the minute green caterpillars munch the grass blades that contain certain fungi that act as bactericides. They may continue to eat on mild days in winter, but always out of sight near ground level. Gatekeeper caterpillars hide on the ground among dense dead leaves of coarse grasses, the brown caterpillars are impossible to find. The Small Skipper lays its eggs in the sheaths of Yorkshire Fog grasses, in rows of about six eggs above each other. The minute caterpillars eat the eggshells, then spin a cocoon around themselves, where they safely spend the winter still inside the grass sheath.

Over wintering as an egg

The Essex Skipper, is difficult to identify from the very similar Small Skipper in flight, but has a different overwinter stage. The flat shaped eggs with tough shells are squeezed between the sheath's of long grasses and laid in rows. The caterpillars fully hatch inside the eggs, but do not emerge until the spring. The Purple Hairstreak, lays its pinhead sized eggs at the base of Oak leaf buds. So, in winter the eggs are high in the trees not on the fallen leaves on the ground. In spring when the leaf buds start to open, the caterpillars hatch and burrow inside and are out of sight.

Migrating Butterflies

The Painted Lady is a true migrant arriving from Southern Europe in the spring. Their young produced in Britain fly south for the winter. Smaller numbers of other species migrate south in winter, just like the birds, for example Small Tortoishell, Large and Small Whites, but most remain as described above. Most Red Admirals will fly south when it gets cold. As winters get warmer we may expect to see other Mediterranean species expanding their range, it's evolution in action. Long-tailed Blue's already have a small foothold on the south coast; others might start to stay including Large Tortoishell, Camberwell Beauty or the Queen of Spain Fritillary.

So, as we turn up the central heating to keep ourselves snug in winter, outside wildlife continues to thrive no matter what the weather. As mere humans, we look forward to the spring when butterflies herald the time when we can get out and enjoy the outdoors, but, before then life miraculously continues out there in the cold.

Guide to Ladybirds

People like ladybirds, probably because they are brightly coloured and look interesting.

They are beetles with striking wing case covers (Elytra).

There are 47 species in Britain. You can’t ‘age’ or determine the species by counting the spots! They vary, even between species. Twenty seven species are brightly coloured, twenty are dull brown. There are common ones that you can identify with a bit of practice and they can be seen all year round, although in the winter months they go into a torpid state and hide, but will wake up and feed if it warms up.

They are like butterflies in that they have a four stage life cycle: Egg, caterpillar, chrysalis and adult beetle.

Many eat aphids as the caterpillar and adult stages, so are welcomed in the garden. In fact when a plant is being attacked by aphids, the plant sends out a chemical signal that attracts ladybirds to come and ‘help’.

Below are seven common species, when you next come across a ladybird, why not try and identify it?

7 Spot: The commonest ladybird. Three spots on each wing and one in the middle:


Harlequin: A big ladybird with many different forms. All have pale brown legs. (7 Spot has black):


2 Spot: A small ladybird, one spot on each wing, there are different forms, but always small:


22 Spot: A yellow ladybird with round black spots, eats mildew on leaf surfaces (Compare to 14 Spot):

14 Spot: Has a Clowns smiley face, with square spots. (Compare to the 22 Spot):


16 Spot: A ladybird that has a line of spots joined around the rim, and a black line down the middle:


24 Spot: A dull red, hairy ladybird with many spots, a red head (other species black), eats vegetation:

Egg:

Caterpillar:

Chrysalis:

If you come across a ladybird or any insect you would like identifying, take a photo on your phone and send it to us. We love a challenge!

Identifying White Butterflies

In Britain we have three species of (common) white butterflies:

Large White, Small White, Green-veined White - there is NO such species as CABBAGE WHITE!

All three species can be seen flying together and can be seen until about the first week in October. It is very easy to tell them apart if you know what to look for.

Large White: Like its name suggests, Large White is bigger than the other two species, but unless they are nearby for comparison, that can cause confusion. Look for the black mark on the corner of the wing - it continues to half way down the wing. In the other two species the corner mark(s) are much smaller.

Small white: Small White is the same size as Green-veined White, about 2/3 the size of Large White. Small White only has a small grey mark in the corner of the wing; it never goes as far as half way down, like in Large White. It only has one mark in the corner, unlike the Green-veined White, which has several marks.

Green-veined White: The same size as Small White, this species has several grey marks in the corner of the wing that look like dark triangles. This species also has dark veins (not green – it should be called Dark-veined White!). Small White has a white background colour; Green-veined often looks dirty-white due to the dark veins.

 

 

 

 

 

 

That is it – simple!

There are differences in the number of spots on the upper wings; you can use these to sex the butterflies. In Large White one or no spots on each wing is a male, Two spots, female. In Small and Green-veined White: One spot = Male, Two spots = Female.

The best way to learn these is to get out and have a look.

And remember - THERE IS NO SUCH BUTTERFLY AS CABBAGE WHITE!!

Plants with umbellifer flowers

Here are three to get you started. Don't be tempted to taste any - they can be fatal! Easy to identify when you know what to look for - lots in flower now along river, roads and paths. Why not a have a go at identifying them yourself on your next walk?

Amaze and bore your friends with your knowledge of bird song

It's not easy though. It's best to concentrate on the abundant sounds and learn to 'switch your hearing on' and learn what is on your doorstep. Great birdwatchers are permanently switched on. When you are tuned in, you can hear what is about without leaving your house!

WOOD PIGEON has FIVE syllables. They say 'I think I love you' or 'My toe hurts betty'. Listen to a Wood Pigeon.

COLLARD DOVE has THREE syllables they say 'United' continually or 'I love you' repeatedly. Listen to a Collared Dove.

Go on give it a go. When these are in your memory banks, you can move on to more species. When you can name everything that is calling around you, that’s when you progress to Attenborough!!

Following on from our last post on the differences in the songs of a Wood Pigeon and Collared Dove, here are three more very common species that are easy to recognise. Listen many times to all songs to pick out the differences. It is like learning a song on the radio - eventually it becomes embedded and the differences are obvious. There is no substitute for hearing them out in the field - but all of these can be heard from your house if you have, or are near, gardens. Then when you've learnt these, the next time you go for a walk in the woods you'll be able to 'tune them out' so you can concentrate on the songs of other birds that are less familiar.

ROBIN: Sings all year round, night and day! A wistful, clear 'sad' tone, singing for long periods with changes of tempo. Listen to a Robin.

DUNNOCK: Fast, high pitched squeaky short bursts lasting 2-3 seconds, repeating several times. No variation. Listen to a Dunnock.

WREN: An excited, rattling vibrant warble ending with a trill. A very loud song for such a small bird. Song longer than Dunnock that has a similar tone. Listen to a Wren.

BLACKBIRD: Slow, lazy, flutey mellow song, the second phase often having a chuckling quality. One of the most common and recognisable bird songs of the Spring. Listen to a Blackbird.

SONG THRUSH: Similar tone to Blackbird but less rich, and always repeating phrases 3 to 5 times, pausing then repeating a new phrase. Although it's easily recognisable without, the repetition is the key to identification. Listen to a Song Thrush.
