 July in the Valley

What you can expect to see...

 

July is the month when most species of dragonflies and damselflies are active. The two types are easily distinguished from each other. Dragonflies are bigger insects, strong fliers and rest with their wings spread Black-tailed Skimmer Chris Kayopen, like the Black-tailed Skimmer pictured (right). In contrast Damselflies are smaller, more delicate insects that tend to flutter around waterside vegetation and rest with their wings folded together over their backs. On a sunny day in July any area of water in the Valley is worth visiting to watch them.

Look out also for emerging dragonfly larvae, coming out of their watery homes and climbing up rushes and other tall water edge plants to make the transformation into adults. This takes place around the water margins and if you’re really fortunate you may spot one as it emerges, but you’ll need to be patient as the whole process takes many hours. In reality you’re more likely to see the empty outer skins of the dragonfly larvae, known as exuviae, fixed to the vegetation.

Summer is high season for butterflies including the Small Tortoiseshell our butterfly of the month. An ancient meadow, which can have upwards of 80 plant species, can support vast numbers of butterflies. As many butterflies specialise on feeding on grasses, any field left to grow in summer rather than being mown short ‘for neatness’ will be worth visiting. Obviously the larger the field the better it will be for butterflies and the more plant species the greater the variety of butterflies it can support. Shepherd Meadows, Hawley Meadows and Hollybush Hill are all Valley sites worth a visit. We leave the grass to grow in the garden at our offices and we’ve spotted several different varieties this year, which can be seen in our butterfly gallery.

Daubenton's Bat Frank GreenawayThe Valley’s flower-rich meadows support
 a wide variety of insect life, which in turn provides food for the Valley’s bat population. Long, warm July evenings are a good time to go bat watching and the best spots to go to are usually found around woodland edges, hedgerows or waterside vegetation. Although the bat species are difficult to tell apart the Noctule is one of the largest British species and is usually the first to appear in the evening sometimes even before sunset. It flies high with sudden downward swoops as it hunts moths that will try to escape the bat as it approaches by plummeting earthwards. You could also see the Pipistrelle, Britain’s smallest bat which appears to have a fast and jerky flight pattern. They fly at or slightly above head height with irregular twists and dives as they dodge about pursuing small insects.

This is a good month to try and spot the Valley’s many young birds as they discover the world. In particular watch out for waterfowl young on the many lakes and ponds as well as along the River itself. In addition to Mallards, Coots and Moorhens look out for the Tufted Duck our bird of the month.

Did you know...?

Common Green Grasshopper

On a warm sunny day any meadow will be full of noise made by grasshoppers
and crickets.

Just as birds can be identified by their different songs, so can grasshoppers and crickets.

Grasshoppers ‘sing’ by rasping their hind legs against their wing edges: they do this by rubbing the tiny pegs found on the inside of their thighs, against a raised rib running the length of their wing. The space between the pegs and frequency of leg movements varies between species giving each one a unique song.

Roesel's bush-cricket
Bush-crickets are closely related to grasshoppers, but they ‘sing’ by rubbing their wings together.

Bush-crickets have longer legs and longer thinner antennae than grasshoppers.
