Book Review: Ladybirds by Helen Roy and others

A few years ago I blogged about raising some ladybirds from eggs that I'd found in the garden. This really began an interest in all ladybirds for me. I saw this book had been published a few years ago, and was eager to learn more but the price was a bit high for me. I managed to get it earlier this year as a used book and it's been my bible ever since (as the Ladybirds of the UK Facebook group sometimes find out).

This book contains so much research that I thought, at first, it may be too advanced for me. After I finished reading the book the following quote, attributed to Albert Einstein came to mind:
"If you can't explain it simply, you don't understand it well enough."

However, this book is written so well, by a group of people who really know what they're talking about, that I had no problems understanding the topics. I learnt so much about ladybirds and where we're at with our knowledges of these beautiful beetles because the text was so accessible. They followed another quote attributed to Einstein: 
"Everything should be made as simple as possible, but not simpler".

The book lets us in on the life cycle of ladybirds, their environment, their natural enemies, ladybird pattern variation, population and evolutionary biology, and ladybird distribution. These are accompanied by a margin glossary that explains words alongside the relevant part of the text as well as lots of tables and diagrams.

The book also has a detailed key to adult British ladybirds, followed by a key to all adult British Coccinellidae, and a third key on the lavae of British ladybirds - all with the aim of providing enough detail that can be viewed without harming the ladybird you're trying to identify.

The book closes with a chapter on how to study ladybirds, for example housing and feeding them, close examination, and how to write up your findings in a report.

I was amazed at the level of detail that has gone into this 142 page book. It doesn't feel cluttered, it flows logically, and it's enjoyable to read.

If you want to learn about British ladybirds, then this is the ultimate resource.



PS. Make sure you record your sightings at: iRecord! The folks over at the ladybird survey (some of whom wrote this book) are very quick to respond to records and really appreciate each record sent in. I recently had a chat with Peter Brown (one of the authors) and he not only answered my questions, but provided a report that was written using the records that have been sent in.

Photography: Topaz Glow

I've really been enjoying messing about with photography this year. In March, I wrote about my first attempts at focus stacking, which I use a lot for the tree flower posts.

I recently came across another piece of software call Topaz Glow. Basically, it's a piece of software that can add effects to photographs you've taken. I imagine, it's not for everyone - and certainly not for every photograph (I've tried quite a few). But, I find it to be a fun tool to use when there's a single subject.

As you can see in the screenshot below, the poppy can be slightly altered - or it can be highly stylised and sometimes unrecognisable.

Here are a couple of photographs that I tried and got results I was happy with:

Plane tree inflorescence. This is the original, followed by a collage of 4 different effects. My personal favourite is the bottom right.



Green shield bug. The original followed by the effect I really liked.


This application is simple to use, while you can change plenty of setting for each effect, such as brightness, sharpness, contrast, strength, etc, I've found little need to. When the effect works for an image, I like it to be bold and vibrant - this isn't a tool I'd use for making subtle changes!

It's not a tool I'd use too frequently, but I can see myself doing sets of photos with these effects just because it's interesting.

Have you used software like this or can recommend any similar tools? It would be great to hear from you in the comments.

Friday Five: Earthworms and the study of

-1-
As it seems with most things, Darwin was the first to take the time to scientifically study earthworms. His final book, The Formation of Vegetable Mould, Through the Action of Worms With Observations on Their Habits, published in 1881 was a detailed study collating his experiment results from a 40 year period about the habits of the worms in his garden at Down House.

Pale Brindled Beauty moth caterpillar - Phigalia pilosaria


Date Photographed: 13/06/2013
Location: Melksham
Resources: http://www.naturespot.org.uk/species/pale-brindled-beauty
Notes: This is the caterpillar of the Pale Brindled Beauty (Phigalia pilosaria) moth. It happened to drop into Lucy's hair as she parked the car under a tree near our house and she found it when she got inside! I've put together this short clip of the caterpillar moving as I like how it grabs the container with it's little 'foot' while moving along:

Notes: Sadly I wasn't able to see the underside of the wing, where the silver streaks are found. This is my best ID from looking at the arrangements of the markings on the upper wing.

Zebra Spider - Salticus scenicus

Date Photographed: 22/06/2013
Location: Tower Road, Melksham
Resources: http://www.bbc.co.uk/nature/wildfacts/factfiles/350.shtml
Notes: This is a really small spider, around 5mm. It is noted for the ability to jump at prey and also, seemingly, its awareness of humans. I noticed that it raised up towards me a few times while I was taking these photos.

Horse Leech - Haemopis sanguisuga

Date Photographed: 25/05/2013
Location: Tower Road, Melksham
Resources: http://www.naturespot.org.uk/species/horse-leech
Notes: I originally thought that this was an immature green worm. But it was noticed on Wild About Britain that there seemed to be a sucker at the end (top right in each photograph). I had a look around and it seems to be a horse leech. Apparently they can survive on land and hunt for snails and worms - luckily not horses or humans!
