Grasshoppers - male seeking females for relationship lasting one summer

Welcome beneficial insects - butterflies, moths, bees and other flying things

There is something very 'back to nature' about the idea of planting your windowbox, garden, estate, to attract bees, butterflies and other pollinators. In the mind's eye - visions of high summer and a green space awash with the flicker of butterflies, zzzit of hoverflies and the satisfying hum of bees.

It is definitely important to encourage insects, some such as butterflies and bees are more welcome than others but many insects help to pollinate fruit and vegetable flowers as well as providing food for other creatures.Birds and mammals such as bats, rely on good sources of flying and scuttling insects as well as their caterpillars and grubs.

Pollinators
Moths often have a bad press, many people dislike them for their habit of clustering around lights at night and generally humming and bumping into things [although some are actually day fliers]. Many also appear rather boring and brown and look similar to the untrained eye and mind [but I can at least recognise a Clothes Moth in situ which is probably useful]. Of the 2400 recorded British moths rather a number are unfortunately garden pests. The Magpie a striking black and white moth apparently favours gooseberries and currants but is in decline and there are all those lovely tortrix moth larvae to contend with - so inviting some of them into your garden is possibly a mixed blessing.

Various flies, lacewings and hoverflies are pollinators and food [as well as aphid control]. As a digression - some of our native plants 'eat' flies [albeit small ones] so should get a mention. Sundews [Drosera] live in generally acidic boggy areas. They derive their nourishment from the flies that get stuck guzzling the nectar that accompanies the sticky goo on the 'leaves'. The 'leaf' gradually curls over the trapped insect triggered by the desperate attempts to escape and digestion begins. The Butterwort [Pinguicula] is another native 'bogger', very small flies get stuck on the leaves and are slowly digested. I have also found that hoverflies like my trumpet lilies which are located near my Sarracenia [a US pitcher plant], the hoverflies initially attracted to the lily were lured in by the pitcher plant and set the pitchers pitifully abuzz as they got trapped and skidded down the slippery throat into the flies composting at the bottom.

I find flies particularly attracted to the unopened buds of Lilium leucanthum [an autumn flowering lily that looks like the earlier flowering L.regale]. Maybe the 'carrion' undertow in the lily's scent was being given off by the bud? Flies are also attracted to the real 'stinkers' such as the Stinkhorn fungus and non natives such as the Dragon Arum [Dracunculus], the smell of rotting flesh again. Many umbellifer flowers also seem attractive to flies.

There are 56 species of native butterflies in the UK and some summer visitors, the most commonly seen are Tortoiseshells and the 'Cabbage' Whites. When planting for butterflies and bees one has to think about the lifecycle. Overwintering species such as Tortoiseshells wake up with the first warmth in spring and need ready sources of nectar, as do solitary and other bees which you see bumbling about on the first warm days.

The next stage for butterflies and moths is to think about the food plants on which they need to lay their eggs for the caterpillars, and finally the late flowering plants that provide nectar prior to hibernation and for later hatches of young.

Nectar and pollen plants
Some butterfly and moth plants are not exactly 'garden plants', for example a number have nettle as a caterpillar food plant [Urtica doicus]. Of course nettles can be made into beer [or so I understand] and you could always go into the nettle weaving business [sort of hemp like], but overall nettles are not the most exciting prospect for the less wild gardener.

So some decisions have to be taken - how wild do you want your garden?

Other choices will be dictated by the area you live in and the soil type - for example some good nectar and foodplants are in the Vaccinum or bilberry family which only grow on acid soils. Most of us have been unwilling hosts to the green caterpillars of the Small White Butterfly or the yellow and grey offspring of the Large White Butterfly [normally lumped together as Cabbage Whites]. They soon make short, messy, smelly lacework of brassicas and nasturtiums. Maybe realistically you only want to be a nectar and pollen garden rather than a foodplant supplier for all?

Spring is an important time to provide nectar and food sources for waking overwintering butterflies and bees.
Aubretia - familiar perennial purple splotches of flowers that cascade from, and over walls. There are quite a few to choose from in varying shades of purple, bluey to pinky - Kitte is one with huge flowers, quite striking if a little intimidating.
Wallflowers [Erysimum] - they are perennials although we mostly discard the bedding varieties after flowering. Other 'shrubbier' types such as Bowles' Mauve, Sprite [yellow] and John Codrington [cream/bronze] have a longer life and can be kept going from cuttings when the plants begin to look too woody. Bedding types can be started off from seed in May/June to flower the following year.
Cuckoo Flower [Cardamine pratensis] - This is a wild flower of damp pastures with pale lilac flowers in April. It is particularly attractive to the Orange Tip butterfly as a food plant. There are some selected forms available including a double flowered plant.
Skimmia - these shrubs are attractive to bees and are in flower from late March - May and are also well scented which is an added bonus.
Also consider: Honesty [Lunaria], arabis, pulmonaria, rosemary and presumably some of the earlier flowering bulbs - one source suggests Anenome blanda as a good early pollen and nectar source.

Nectar sources are in much greater abundance through late spring into summer: Consider the 'labiates' which are attractive to many insects, these include, nepeta, agastache, hyssop, mints, thyme, origanum, salvia and marjoram. Borage is a good bet as are others in the family which include echium and alkanet. Knautias and scabious are another family group [teasels] to look out for especially as a number are later summer flowering. Umbellifers seem to be more attractive to flies and hoverflies and are an acquired taste for some, they include angelica, sweet cicely and astrantia. Thistles are popular with some insects and there are a few that have made it into the garden including Cirsium rivulare Atropurpureum and Galactites tomentosa, other pricklies include acanthus [Bees heave their way noisily into the heavy flowers] and echinops. Good later flowering shrubs include hebe and buddleja. Brambles are noted as popular nectar plants for many moths and butterflies, whether this applies to more ornamental Rubus I don't know. And finally not forgetting Poached Egg Plant [Limnanthes] which is easily grown from seed, and single Marigolds [Tagetes].

By the autumn as food sources start to decrease it is a good idea to choose some later flowering plants.
Sedum - often known as the 'Butterfly Plants' are classic for late summer. The flowers range from white to deep pinky reds, some have lax growth, others are more upright. Foliage comes in plain soft green, variegated to various purples such as Purple Emperor - deep purple foliage. I have found some are difficult to establish well.
Asters - many are available including the singles with clouds of small daisy flowers. Aster turbinellus has tall purple stems and sprays of lilac flowers and is one of the latest to flower with me.
Solidago - Golden Rod, not exactly a favourite flower of mine but there are some more delicate selections around if the blaring yellow is a bit overpowering.
Also consider: echinacea, heleniums, eupatorium, lythrum, sunflowers [helianthemum] and caryopteris.

Native and wild food plants for caterpillars
This is a random rather than exhaustive selection of the moths found in the UK and some of the butterflies [OK so I chose the moths for their names]. Quite a few moths have trees as their main caterpiller foodplant and some of the butterflies stake out their territories in trees but don't feed on them e.g. Speckled Wood. Others feed on grasses and weeds such as dock, dandelion and bindweed [hooray!].

Some have plants they resort to if the main one is in short supply. The Cinnabar Moth with its satin black, red spotted wings favours ragwort and groundsel but I have seen its black and yellow banded caterpillars on the silver ornamental senecios too.

Night fliers
Some of the night flying moths are attracted to the flowers that start to pump out their perfume as evening falls, these include Honeysuckles such as Lonicera Peryclimenum [Woodbine] and L. caprifolium; Tobacco plants such as Nicotiana alata and N. sylvestris; Evening Primrose [Oenothera speciosa] and Dame's Violet [Hesperis matronalis]. Pyracantha in flower also seems to come alive with moths just around sunset.

Grasshoppers
Not strictly pollinators but a summer garden wouldn't be the same without the scratching of these insects. Those pictured at the top of this page are Meadow Grasshoppers, I sometimes see the brown Field Grasshoppers in the garden as well. They lay eggs in soil in shorter grass which overwinter and start to hatch in May. And yes they eat grass I have watched them devour blades.

What is it with Beetles and weevil? Some are beneficial it's true - but others are not at all welcome - you don't want Lily Beetles, cheerful orange beetles which lay orange eggs on the undersides of lily leaves and other plants in the lily family like fritillaries. The grubs cover themselves in excrement, heartily munch away at the host plant and then hibernate in the soil to emerge all glossy and triumphant on warm days in May and June. If seen, cup your hand under the leaf [they drop to the ground very fast if you miss] tap gently and Squash! Asparagus Beetles are also cheerful sparkly looking little beetles with a similar habit - be warned.
