Minibeast Monday - Getting to Know Your Beetles

COLEOPTERA (Beetles)

About a quarter of all species of animal life on Earth are beetles, and there are getting on for half a million described species of them. That's a lot of beetles to sort out, so how is it done? Basically, by dividing them into smaller and smaller groups. Beetles form the order COLEOPTERA, a name coined by Aristotle about 2,350 years ago, meaning 'sheathed wing'. This refers to the fore wings of beetles which are hardened to protect the hind wings. These hard fore wings are called elytra, and distinguishes beetles from all other insects. The order COLEOPTERA is broken down into five suborders, one of which, PROTOCOLEOPTERA contains very old beetles, all of which are now extinct and there are two very small suborders: ARCHOSTEMATA which contains 45 species, and MYXOPHAGA which contains 65 species. The majority of the beetles that you meet, however, will either be in the suborder ADEPHAGA or the suborder POLYPHAGA, so let's have a look at those in more detail.


ADEPHAGA


The ADEPHAGA is the smaller of the two suborders containing some 40,000 species of Ground and Water Beetles, which, as their name suggests, you'll either find running along the ground or swimming in water. (The technical difference between an Adephagan and a Polyphagan is in the way that its hind legs attach to its body.) The eleven extant families within the ADEPHAGA are:

Amphizoidae (troutstream beetles)

Aspidytidae (cliff water beetles)

Carabidae (ground beetles)

Dytiscidae (predaceous diving beetles)

Gyrinidae (whirligig beetles)

Haliplidae (crawling water beetles)

Hygrobiidae (squeak beetles)

Meruidae (Venezuelan waterfall beetle)

Noteridae (burrowing water beetles)

Rhysodidae (wrinkled bark beetles)

Trachypachidae (false ground beetles)

POLYPHAGA


The POLYPHAGA contains all the other beetle species, and as there are over 350,000 other beetle species, the order is broken down into five infraorders:

Bostrichiformia (includes furniture beetles and skin beetles)

Cucujiformia (includes lady beetles, longhorn beetles, weevils, checkered beetles and leaf beetles)

Elateriformia (includes click beetles and fireflies)

Scarabaeiformia (includes scarab beetles, stag beetles, and dung beetles)

Staphyliniformia (includes rove beetles and water scavenger beetles)

The hyperlinks above have been collated from Wikipedia and will take you to the relevant beetle type. Last month, in Minibeast Monday, we looked at weevils. As you can see from the above, weevils are polyphagan beetles in the infraorder CUCUJIFORMA. As we continue to find more beetles on our Minibeast Monday safaris, I'll link back to this page so that you can see how they all fit together. These are the beetle books that are currently in the Build Your Own Nature Library



All the best,

Fell Walking For Wimps 1 - Slate Fell







Twenty years or so ago, if I saw a hill, I felt an irresistible urge to climb it. Now, older and wiser, I have come to realise that majestic mountains and fabulous fells look at their most majestic and fabulous when they’re towering above you. True, when you get to the top, the views can be breathtaking, but these days, by the time I get to the top, I’ve not got a lot of breath left to take. Which is why I’ve decided to introduce the idea of Fell Walking For Wimps. No-one else appears to have bagged the title yet, so I’m having it.

Our little walk today takes us up over Slate Fell, to the East of Cockermouth, then back round to where we started, in a five mile triangle. Unlike Scafell Pike, England’s highest mountain (also in Cumbria), which rises to a little over 3,200 feet, Slate Fell is a far more modest 520 feet, and as we are starting at 220 feet then we are merely going to be strolling up hill at the start.

About three quarters of the way up now, and this little bank looks worthy of closer investigation. Let’s sit and take a closer look at it. No, it is not just an excuse for a rest. I’m still fighting fit. Starting with the yellow flowers which are not dandelions [dandelions have hollow, often pinkish, stems]. These are more closely related to chicory, look at the leaves. I see that there’s a bumblebee taking advantage of this pit-stop to refuel. That little mauve flower up the bank is wild thyme. There are two species generally to be found in Cumbria, Thymus praecox and Thymus serpyllum. I think this is the former. Combined with parsley, in a white sauce, it’s terrific with fish. One for Steve's Wild Kitchen when I eventually get the keys to my new flat. But, back to our bankside, even this scrap of sheep’s wool isn’t devoid of interest. There are tiny flies in it looking for even smaller things to eat. OK, that’s enough rest, um, investigating, for the moment. Onwards and upwards.

Naturalists, as you probably know, have an unhealthy preoccupation with dung. I’m no different, and I’ve noticed a lot of cow pats up here, so, let’s find a nice, sloppy one and see who’s at home. Flies, as you would expect, but a bit prettier than your common house fly. The big one, with a flash of orange on her wings is a Noon Fly (because you often see them in the middle of the day), and the little greeny/gold job is a Yellow Dung Fly. Both of these flies lay their eggs in this nutrient rich cow dung and their maggots help in its decomposition, ensuring that we’re not wandering about knee deep in the stuff. The other little fellow is a Water Scavenger Beetle. Most Water Scavengers are aquatic, as their name suggests, but these are specialists. They also lay their eggs in cow dung, but their larvae don’t eat the dung, they feed on the maggots of the flies. There’s a whole world of life going on in a cow pat.

We’ve now reached the Embleton road and we’re going to take a quick right turn and change from footpath to bridleway. That’s it, stretching out before us and there’s far more plant life as it is ungrazed. Quite a pharmacy in fact. For a start, we have some Selfheal, which the Native Americans use to treat boils, cuts and inflammations. Mixed with other herbs, such as mint, which we also have in here, it is supposed to be effective against halitosis. Mint, as well as being a good culinary herb, is well known for easing an upset stomach, and we also have some Wild Angelica here. You have to be very careful with this one as it looks so much like other umbilifers such as Cow Parsley and Hogweed. Up until the 20th century, both the stems and leaves were used as a vegetable and, medicinally, it was used to cure scurvy.

Here we are at the end of the bridleway and it’s about three miles back along country roads. It may not look too interesting but there’s a magnificent hedgerow and verge, a habitat in decline across the UK, and just to prove it’s importance we’re going to count the number of different plant and insect species that we see. Firstly we have some Ox-eye daisies being pollinated by various flies and wasps, including this lovely Marmalade Hoverfly. These are marvellous little flies that overwinter in the Mediterranean and then come all the way up here for the spring and summer in a multi-generational leap. We’ll record this one for the Marmalade Hoverfly Monitoring Scheme which is keeping an eye on them as indicators of the effects of climate change among other things. Next we have something which you may not recognise as an insect at all. These pompoms on a wild rose stem are the product of the Mossy Rose Gall Wasp. These are taken advantage of by another species of gall wasp that lays its eggs in the nutritious bundle, and the larvae of both wasps are likely to have two more wasp species lay their eggs in them! Finally, the whole lot may be eaten by a small mammal in a sort of two wasp roast. Some more ox-eye daisies now, this one being pollinated by our little friend from the cow pat, the Yellow Dung Fly, taking on some much needed fuel and down here, taking a rest in the grass, is a Shaded Broad-Bar moth.
I make that 43 different plants and 22 different insects. This will provide food for numerous small mammals (and big ones, I saw you stuffing yourself with blackberries along the way), as well as an important corridor between habitats.

Just a short stroll now, back to our starting point, but we’ll just pause at this little bridge over Tom Rudd Beck to look at the handiwork of the local children, commemorating this strange old year.


Quick admin note: I’ve changed the style of the blog to make it clearer and easier to follow by email or feed.




Until next week,

Stay safe and be happy,

Steve







All you need to know to identify any type of insect, spider, worm or snail very simply and find out more about it.
Yvonne: This was a gift for a family so that the children can understand what they see on days out. The second was for me. Logical and easy to use. If you know anyone who likes nature you can be confident that gifting this book will give years of pleasure.


The Eggs of Saramova
A science fiction novella for those who don't like science fiction. A fast-paced thriller that is, literally, out of this world (and it starts right here in Crete).
Too new for reviews yet!


A light-hearted look at life through the eyes of the fairer sex.
Janet: If you are short on time but enjoy reading and are maybe not into long extended novels then Not Just For... Twisted Women provides readers with concise stories that stand alone and most certainly entertain with their ultimate twists. Loved it.
Helen: A very good read! Well written and entertaining!
Margaret: Each quick tale gives a glimpse into a character's life and has an often humorous twist at the end. I would love to read more.
Yvonne: These days many people find it hard to find the time to read a novel, so this book of short stories is ideal to dip into. It is also makes a good gift.
