Wildflower meadows

Gorgeous pictures taken in our wildflower meadows by wildlife photographer Simon Knight and sent in with a question:

Here are some pictures from the reserve taken over the past few weeks. It’s a shame we’re about to lose most of the flowers and a huge amount of invertebrate life with the grass being cut so early. Why can’t the grass be cut later in the summer?

Bumblebee flight

For a long time, bumblebee flight was considered to be aerodynamically impossible. We know better now and are beginning to understand how such fat furry creatures can take to the air. Here is a video about their surprising flying skills:

There are three species of woodpecker native to the UK. Two of them, the green woodpecker and the greater spotted woodpecker, nest in our reserve. Here is a short video to help you tell them apart.

Breakfast

A moment’s predation in our nettle beds, photographed one morning last week by Ian Bushell: a crab spider, probably Xysticus cristatus, has caught a red and black froghopper, Cercopis vulnerata, for breakfast. Crab spiders don’t build webs, they lie in wait and pounce on passing prey.

On Wednesday, Ian found a dead hedgehog:

“Returning to the car park, towards the bottom of Simpson’s Field, I came across a dead hedgehog. It had been eviscerated, so most likely was killed and eaten by a badger. This is the first evidence of hedgehogs in the reserve since 2014.”

Here is a link to a recent post about the complicated relationship between hedgehogs and badgers.

Another new species

An ashy mining bee (Andrena cineraria) seen yesterday in the reserve, and photographed by Clive Knight. This is a female with two distinct bands of grey hairs across her thorax and a black, shiny abdomen.

Is a hibernating bat safe?

Underground bat hibernation sites, called hibernacula, can attract predators. Finding signs of predation among the bats overwintering in twelve World War II bunkers in Zuid-Holland in The Netherlands, researchers set up trail cameras to identify the culprits.

Swift

Data collected by researchers from Lund University in Sweden show that common swifts spend almost their entire 10 month non-breeding period in continuous flight. Nearly all of the swifts returning to nest sites in and around Trowbridge this summer from their winter home in sub-Saharan Africa will have been in flight non-stop since they left us last year.

Whirligig beetles

Whirligig beetles are actually a whole family of water beetles called Gyrinidae, almost 700 different species globally, most of them very much alike and extremely difficult to tell apart. We have no idea what particular species live in the pond upstream of the wooden bridge but all the Gyrinidae share some fascinating features.
