Amazing Insects

Posted on by BITM

The first of August is the start of the harvest and autumn is beginning to set in slowly now; a time I enjoy.

The weather has recently changed in the south, we have had rain over the past few weeks, meaning the parched lawns are beginning to green up once again and require cutting. I have never known a year where we haven’t cut the majority of lawns for such an extended period over the summer; usually it isn’t until the end of July into August when this occurs.

The wetter conditions are making it difficult to pick a time to undertake the Big Butterfly Count this year, although I am still seeing various butterflies and day flying moths around at the moment; Including the Jersey tiger moth (Euplagia quadripunctaria).

This beautiful medium sized moth (between 5.2 to 6.5 cm in length) is often seen in the south with the range growing upwards towards London and now Hertfordshire; found in Gardens, hedgerows and coastal areas. The caterpillars can be found between September through to the following May, surviving winter as larvae. The adults often visit Buddleia while the food source for caterpillars are Common Nettle (Urtica dioica), White Dead-nettle (Lamium album), Borage (Borago officinalis), plantains (Plantago Spp.), Ground-ivy (Glechoma hederacea) and Bramble (Rubus fruiticosus) amongst other herbaceous plants.

I have also seen a small copper (Lycaena phlaeas) butterfly recently.

This small (3.2- 3.5 cm) orange coloured butterfly can be found on waste ground as well as heath, moor, grass and woodland environments where the soil is chalky and the ground poor in nutrients. The caterpillars eat Sorrels and Broad-leaved Dock (Rumex obtusifolius).

This has been a wonderful year for ladybirds due to the very hot weather at the beginning of spring causing a huge increase in aphids. Out of the 46 different types in the UK, I mostly see Six-spot and Harlequin ladybirds.  A couple of weeks ago I noticed another as it flew into the van; the 14 Spot ladybird (Propylea quattuordecimpunctata).

Much smaller than the six-spotted ladybird, this yellow and black beetle can be seen throughout the UK from May to September.

I finally saw a flower crab spider (Misumena vatia) while pruning a shrub too. As seen in the photo below, they are often white but the females of the species can change their colour to a yellow tint in order to blend into its surroundings better.

Usually noticed between May and August they are commonly seen in southern England. The different sexes differ in size, the males are half the size of the females which are between 9 to 11mm in length. These spiders will wait and ambush prey rather than spin webs and can eat various insects including moths and bees,

Witnessing the Solstice Dawn Arrive

Posted on by BITM

On the eve of the Summer solstice I love to go to sleep early with my curtains open so I can wake up naturally and see the sunrise; it helps me align with the seasons and appreciate nature in a different way. This year I awoke at 3:50am and immediately opened the window so I could enjoy the dawn chorus. Initially the predominant birdsong was that of Blackbirds (Turdus merula), occasionally punctuated by the calls from a Wood pigeon (Columba palumbus), a murder of very vocal Carrion crows (Corvus corone), along with a male Pheasant (Phasianus colchicus) in the distance too. The crescendo came around 4:10am but it wasn’t until finally at 4:42am, when things had quietened, that I heard a few more birds singing. There was a lone Dunnock (Prunella modularis) and then a Greenfinch (Chloris chloris) at about 4:50am; followed much later by Blue tits (Cyanistes caeruleus) which I observed in the Rowan (Sorbus) tree nearby.

It’s interesting to notice an order to the bird song. Blackbirds are the first to be heard, almost like they are an alarm call for the other songbirds; clearly eager to catch the worms.

I also learnt another birdsong last week, heard around midday on Thursday. Hidden somewhere amongst the treeline next to a field, was a Common Whitethroat (Curruca communis); the song can be heard here on the RSPB website.

This warbler visits the UK from Southern Africa (from countries south of the Sahara) between April and October. Once the males arrive on these shores, they will establish territories and build nests for prospective partners (approximately ten to fourteen days before the females arrive).

These birds are about the same size as Great tits (Parus major) and named after the white plumage on their throats. Males can be differentiated from female due to their grey heads. They feed on insects as well as fruit and berries later in the year.

After being concerned that I wasn’t seeing many butterflies and ladybirds the previous week, last week
it finally became warm and sunny enough for them to venture out once again. It was lovely to witness a couple of Small tortoisehell butterflies (Aglais urticae) along with some bumblebees visit a Scabious plant in one garden.

Plus there was a loveliness of Seven-spot ladybirds (Coccinella septempunctata) at the allotment, hunting down on all the aphids which also appeared.

Butterfly Numbers Flying High.

Posted on by BITM

With Buddleia, Lavender and Verbena bonariensis in full bloom at the moment butterfly sightings have increased significantly.

Along with plenty of Peacocks (Aglais io), Red Admirals (Vanessa atalanta) and Large whites (Pieris brassicae), I noticed a few other butterflies last week.

The first was a Gatekeeper (Pyronia tithonus) visiting Shasta daisies (Leucanthemum × superbum),

but I also saw a Comma butterfly (Polygonia c-album) pollinating some Verbena bonariensis too.

Along with these butterflies, the European gypsy moth (Lymantria dispar) reappeared, still under the Rhubarb patch on the allotment (see my ‘All you Need is Love and Nature.’ post from the 29th June 2020). However it was no longer a caterpillar but in the next stage of its life cycle, a pupa hanging from a Rhubarb leaf.

It can be in the Pupal stage for a fortnight so I will keep checking for its emergence as the adult moth, so I can hopefully see it take place. As I don’t exactly know when the Pupal stage began I’m not sure how soon it will occur. The male and female moths look very different so can be easily identified, plus the females don’t fly (see Butterfly Conservation); therefore if no moth is found then it was probably a male that has flown away.

The last insect that was noticeable last week was a Common red soldier beetle (Rhagonycha fulva).

It is always great to see these beetles as the are beneficial insects which predate aphids while their larvae eat
invertebrate pests, slugs and snails.

An Enchanting Week

Posted on by BITM

My interest in plants extends to herbal medicine and floral folklore. Often found in gardens, such plants are easily accessible.

I find poisonous plants fascinating too. I would like to visit the Chelsea Physics garden as well as the Alnwick Poison Garden in Northumberland. Over the past week, a few wild flowers that I have noticed blooming would probably be found in these gardens, these are;

– White bryony (Bryonia dioica) scrambling over Dogwood (Cornus). White Bryony has poisonous berries and the plant has a very strong unpleasant purgative affect. A few deaths linked to this plant have been recorded.

– Woody Nightshade (Solanum dulcamara).

Also called Bittersweet the plant would make someone incredibly ill; the berries if eaten would cause vomiting and convulsions. There have been a few deaths linked to this plant. It is from the same family as Deadly nightshade (Atropa belladonna, See Woodland Trust).

I saw other wildflowers blooming too such as the intriguingly named Enchanter’s nightshade (Circaea lutetiana). Confusingly this flower isn’t from the nightshade family at all but is actually a Willowherb. One folkloric belief was that this plant would give protection against Elvish spells.

I also saw Field bindweed (Convolvulus arvensis) along the verges.

I continued to see many birds and insects throughout the week. After many days since the last time, I was happy to see the juvenile Blue tits (Cyanistes caeruleus) back in the Rowan tree (Sorbus). Also on Monday I had a Juvenile Robin (Erithacus rubecula) follow me around. Clearly the instincts for locating food near gardeners starts early.

The first moth I saw last week was an adult female Bee moth (Aphomia sociella). These moths are so called because they lay eggs in bee and wasp nests and also bee hives. Their larvae eat the comb, causing damage and are therefore a pest for beekeepers.

Other moths I saw were two Rosy tabby (Endotricha flammealis) moths

and a Dark arches (Apamea monoglypha) moth.

On Wednesday I was working near a fantastic old Sweet chestnut (Castanea sativa) tree. Countless Honey bees (Apis mellifera) and Marmalade hoverflies (Episyrphus balteatus) were busy flying to and fro pollinating the flowers.

As the summer continues more and more butterflies become visible. I have seen lots more Meadow brown (Maniola jurtina), Small tortoiseshell (Aglais urticae) and Large white butterflies (Pieris brassicae). One of them seen here on some lavender (Lavandula).

Also on Wednesday I observed two butterflies that I have never seen before, a Marbled white (Melanargia galathea) on Verbena bonariensis

and a Small skipper butterfly (Thymelicus sylvestris), also seen on the Verbena bonariensis.

Later on the same day I also saw ten Azure damselflies (Coenagrion puella) around the pond.

On Friday morning, as I was going to work, I had to usher a Common green lacewing (Chrysoperla carnea) outside so it could find some aphids to munch on.

Then lastly on Friday I saw a Harlequin ladybird (Harmonia axyridis) on Brunnera macrophylla ‘Jack Frost’.
