Whilst Bob has been doing a brilliant job of blogging his 30 Days Wild antics, this week is also National Insect Week. Organised by the Royal Entomological Society, it encourages everyone to appreciate and learn more about the ‘little things that run the world’.
Insects are by far the most diverse and ecologically important group of animals on land and there are over 24,000 known species in the United Kingdom alone, with hundreds of species to be found in almost every garden and green space. With so many to study they are grouped into orders, for example the Lepidoptera (butterflies and moths), Odonata (dragonflies and damselflies), Hymenoptera (bees, ants and wasps), Orthoptera (grasshoppers and crickets) and Coleoptera (beetles) to name a few.
Insects have a huge role to play and without them our lives would be very different: they pollinate fruit, flowers and vegetables; they are food for amphibians, reptiles, birds and mammals; and they feed on lots of living and dead things themselves, breaking down waste and helping to keep the balance of nature. You can find out more about National Insect Week on their website.
So here’s a very mini Blashford insect safari, using photos I’ve taken over the past few days, covering a very meagre 23 species and spanning five orders – I have quite a few more to track down!
The moth trap has revealed some spectacular moths over the past few days, including some very smart Privet and Elephant hawk-moths:
There was also another Scarce merveille du jour, with its lichen coloured forewings which provide it with brilliant camouflage:
Other species included a swallow-tailed moth, peppered moth, pebble prominent, lobster moth, large emerald, iron prominent, buff tip and barred straw:
The raised planters outside the front of the Centre are still a good place to look for insects, with plenty of bees, ladybirds, and butterflies making the most of the flowers:
There has also been a red admiral regularly resting on the fence posts and gravel outside the front of the Centre…

…and I also found this Figwort sawfly on the mullein by the corner of the building:
Figwort sawfly, Tenthredo scrophulariae
I’m not sure I’ve seen the sawfly before, or if I have I don’t think I’ve had the time to photograph and identify it, so it was nice to find a different species. Its striking yellow and black bands mimic a wasp and whilst the adults will sometimes nectar on flowers as this one was doing, they will often eat other insects. The larvae feed on either mullein or figwort.
Where we have not been using the grassy area by the side of the Centre for school lunches and Wild Days Out free play, the grass has been able to grow nice and tall and a few other plants have sprung up, particularly around the tunnel. One plant in particular seemed popular with the bees and volunteer Phil tested out his plant finder app on it for me on Tuesday as I had been trying to identify it without much success. It reminded me a bit of dead nettle.
Known as Black horehound (Ballota nigra), it grows along hedgerows, road side verges and on waste ground and belongs to the mint and dead nettle family, Lamiaceae. When the leaves are crushed it gives off a pungent rotten smell to deter herbivores (perhaps we need to relocate some into the planter by the Centre which has been targeted by the deer) which has given it the local name of ‘stinking Roger’ in some places. It also has a long tradition in herbal medicine and has been used to treat a range of issues from respiratory problems to travel sickness and depression to gout.

There have been a number of emperor dragonflies hawking over the Centre and ponds and yesterday I spent some time sat by the pond watching a male fly overhead, occasionally dive bombing me. Every so often he would return to one particular iris to perch, either on or above the exuvia that was still clinging on, so I guess this could have been where he emerged:

This damselfly was not quite as fortunate as I found it in the firm grasp of a zebra spider who was doing an excellent job of carrying it around the post to devour in peace:

In venturing further from the Centre to check the reserve, I had a brief glimpse of a fritillary along the Dockens path and managed a quick photo. I think it’s a Silver-washed fritillary:

In studying all the mullein I came across in the hope of stumbling across a mullein moth caterpillar, I had to settle for this grasshopper instead, although it did pose very obligingly for a photo:

Now is definitely a good time to find and watch insects, and you don’t need to venture far to track them down as even the smallest garden or green space can provide a home for this incredibly diverse group of animals. So if you get the chance head outside and see what you can find!
Moving away from the insects, I ventured into our woodland log circle area on Sunday and it has certainly enjoyed the lack of bug hunting children, I don’t think I’ve ever seen it so green and grassy. On a number of logs I found the fruiting bodies of the slime mould Lycogala epidendrum, also known as wolf’s milk or groening’s slime. If the outer wall of the fruiting body is broken before maturity they excrete a pink paste.

Finally, although they have been disappearing very quickly with the warmer weather, the grass snakes by Ivy Silt Pond have been very obliging, with two often on the stretch of hedge immediately behind the temporary sign:
