To round off an eventful year here at Crunchy on the Outside, we have put together a quiz for you combining our two favourite things: Insects and Christmas!
There are ten questions in the video. Each of the answers is formed by smashing together the two clues. One clue is about insects, the other about Christmas. We’ve included a couple of examples at the start to help you get the hang of it. Don’t worry if a question seems tricky, it’s just for fun and we’ve included some clues below.
The scientific name of this insect is Colletes hederae.
Insects that have been trapped in amber (fossilised plant resin) can be preserved in amazing, stunning and beautiful detail. This short video shows you how to make a fossilised insect themed decoration that can be hung on your Christmas tree for the festive period, or can be displayed around you home all year round.
I have included the written instructions in case you find them helpful.
You will need:
A glue stick
Card (e.g. cereal box)
Orange cellophane sweet wrapper(s)
Take two pieces of card that are roughly the same size. Put them together with the plain sides facing out.
On one side draw a frame, at least 1cm thick. It can be any shape you choose.
Carefully cut out the frame, including the middle.
Check that your cellophane wrapper will cover both frames. If not, use two.
Use the glue stick to attached the cellophane to the patterned side of the frames.
Trim the cellophane around the frames.
Take a small piece of paper that will fit inside the frames and draw an insect on one side. Trim the excess paper around the insect and then draw a similar insect on the other side.
Use the glue stick to attach the frames together with the insect in the middle, and with the wool/string forming a loop that you can use to hang your decoration.
Decorate your frame using coloured pencils, pens, glitter or anything else that you choose.
We would love to see your amber decorations. Also, can any of you spot the key feature of an insect that I forgot to draw to my insect picture in the video? Let us know in the comments, or by the Contact us page.
To find out more about Insects in Amber look out for a post early next year.
The Spotted Wing Fruit Fly, Drosphila suzukii, (known as ‘SWD’ for short) is a small but potentially devastating pest that attacks soft fruits. Here’s how to make a simple trap from a plastic bottle. You can then see if you have caught any fruit flies and send your results to an exciting citizen science project.
Making your Fly Trap
You will need:
A large empty clear plastic bottle (perhaps a fizzy drink bottle or squash bottle)
Apple cider vinegar (cheapest from a supermarket)
An auger, awl or large nail (2 mm to 3 mm diameter)
Start by watching this video by Chris Thomas of the Queckett Microscopical Club.It shows each step of making the fruit fly trap.
Step by step Instructions:
This bit needs an adult to help. Carefully pierce 8 holes in the bottle more than half way up, using the augur or nail. Lie the bottle on a table or board. Hold it firmly at the bottom half and gently pierce with a sharp metal point or augur, through the upper side of the bottle towards the board. If the point slips, it should then go safely into the table or board and NOT into your hand. Make the holes 2-3 mm in diameter, to let in small flies. I used a sharp augur to pierce the plastic and then a wider diameter nail to enlarge the hole.
Fill the upright bottle to ¼ to ⅓ with apple cider vinegar. The level must be below the holes!
Add one or two drops of washing-up liquid.
Screw lid back onto plastic bottle.
Use the string to hang your baited trap from a tree/bush/holder at a suitable place.
Leave the trap for one week.
At the end of the week, seal up holes with sellotape.
Swirl bottle gently and carefully pour the fly catch into a white / light coloured plastic dish. (OPTIONAL: strain the fly catch through an old metal tea sieve and then transfer the flies to clean water with a bit of vinegar in it to preserve them.)
Record your results (see below).
At the end of the experiment, wash and flush away the flies and liquid. Wash the plastic bottle thoroughly and recycle it. Don’t forget to wash your hands.
2021 Spotted Fruit Fly Survey
If you have caught some fruit flies, you could send your results to the 2021 Spotted Wing Fruit Fly Survey and help track the spread of this pest across the UK.
The Spotted Wing Fruit Drosophila (SWD) is a pest in many parts of the world because it causes damage to soft fruits. It was first spotted in the UK in 2012 and this survey aims to find out how far it has spread. Counting and scoring the results from your trap will be really helpful and we will link your results with those from many other people. The more people who contribute, the more we can learn about the biology of this pest.
Fruit flies are small – only a few millimetres long – but can be identified by a couple of key features with a hand lens, low power microscope, or by using a mobile phone camera (see below). The male flies are easily identified by their characteristic wing spot. The females don’t have the wing spot but do have a vicious-looking saw-like egg laying organ (called an ovipositor) at their rear end.
You might like to use your fruit fly trap to catch Spotted Wing Drosophila over a week, count what you have caught and send the results to Chris Thomas of the Quekett Club at firstname.lastname@example.org the end of November.
The Club aims to collate all the results and publish them in the Quekett Journal, mentioning all participants who submit results.
Either use a magnifying glass or a low power microscope to magnify the catch. Don’t worry if you don’t have one – watch our video Turn Your Phone into a Microsope.
Fruit flies are very small, between 2 mm and 5 mm long. They are quite distinctive.
Use the pictures to help you identify the Spotted Winged Drosophila.
The male flies are obvious even to the naked eye – they are red-eyed fruit flies with a black spot at the end of the wing. Under magnification, they also have 2 spurs on their forelegs.
The female flies are best viewed under 10× to 30× magnification: they have no spots but their saw-like ovipositor (egg-laying organ) can be seen clearly. Once you have seen one, you will never be confused. They also have clear black and yellow bands on their abdomen.
Record your results and send them to the Quekett Club
You should include:
Name and address (or just your post code, if you don’t wish to be named as a participant)
Date when you emptied the fly trap
Total number of ALL insects/creatures in trap
Total number of ALL fruit flies
Number of male Spotted Wing Drosophila
Number of female Spotted Wing Drosophila
The Queckett club would love to see pictures of your catch, so please add them too
It’s really important to record and send in ALL results – even if you did not catch anything!
If you don’t catch anything, enter ‘Nothing’
If there are no Spotted Wing Drosophila, but you see other fruit flies, enter ‘Common Fruit Fly’
If you can’t decide if they are males or females, just tell us the total number of SWD
Make sure you send your survey results to Chris Thomas at the Quekett Club, but the team at Crunchy on the Outside would also like to see your fly traps and catches! Let us know how you got on by emailing us at email@example.com or using the Contact Us form.
What if you need to look at something really small but you don’t have a microscope? You can can try taking a close-up picture with a smartphone or camera (use the ‘macro’ setting if it has one) and then magnify the image by zooming in on the picture using a PC or tablet screen.
Alternatively, we’re going to show you how to hack your phone to turn it into a microscope. You don’t need any technical skills or special equipment – just some honey!
Honey Lens Hack
You can buy magnifying lenses which are designed to sit over a phone camera lens, but our video shows you how to use a drop of honey as a temporary magnifying lens. You don’t need much, just these five things:
Clear plastic packaging (e.g. plastic fruit carton)
Blu tak (or similar)
Clear honey (if your honey has gone solid, the video shows you what to do to solve this)
You’ll probably need to experiment a bit with the size of honey drop you use exactly how far from the lens to position it to get the best image. With a little bit of practice you should be able to make a useful temporary magnifying lens.
Wildlife photographer and insect enthusiast Kirk Mason shares his top tips for taking fabulous insect photos, whatever camera you have.
Well done to everyone that came to the Summer School photography workshop. I was blown away with your photographs, videos and knowledge of insects – well done!
Let’s recap on some handy hints to improve your photography.
1. Getting down to the eye level of insects.
One of the things that makes photographing insects and other invertebrates so awesome is that you start to see things in photographs that you would have missed with just your eyes. Getting down to the eye level of insects makes them look bigger, more impressive and can take your viewers to a perspective they wouldn’t have seen without you. If you compare these photographs, which do you prefer?
2. Empty space.
Leaving empty space in your photographs can make your subject really stand out. It leads the viewer’s eye to what you want them to focus on or show your subjects in their environment. You can use the rule of thirds to get a feel for how much empty space you should leave – ideally the subject should take one third of the space, and two thirds empty space. Though artistic rules are made to be broken, so the best thing to do is experiment and see what you like most! Check out the examples below to see what you prefer.
3. Background is everything!
Leaving empty space can look great, but if the background is messy or doesn’t look nice to you, it can take away focus from your subject. Most insects and other invertebrates are tiny, so moving around the insect by a few centimetres can really change the look of a background and the feel of a photograph. See below for examples of a bad background made better by moving a few inches, which do you think looks better?
4. Focus on the things that you find interesting about the subjects.
They say the eyes are the window to the soul, and whilst invertebrates do not show emotion through their eyes, they are often super interesting to look at! Typically, having the eyes in focus makes for great photographs, however invertebrates have lots of interesting features that are great to see up close! Wing patterns, antennae shapes and even feet are super diverse and make for great photographs – here are some examples of things I find interesting, do you?
5. Practice makes perfect!
Photography is like many things we do in life – the more we practise, the better we become! Luckily, going out finding insects and photographing them is great fun. This makes improving feel almost effortless and with thousands of insects to find in Britain, it’s hard to get bored! Wind and fast-moving insects make it hard to get good photographs every time, so the more you take, the higher chance you have of getting the shot you want. I still throw away way more photographs than I keep! I started my photography journey three years ago and have since had my photographs on BBC Springwatch, and in BBC Wildlife magazine and several newspapers. See below for my first photograph that I was happy with and compare it with what I take today. You all took fantastic photographs and if you keep doing it, by the time you are my age, you will have taken the world by storm!
Inspired by these top tips? Have a look at our Photo Gallery and then have a go for yourself. As Kirk says, practice makes perfect! We’d love to see the results: you can email your best photo to us at firstname.lastname@example.org. Please make it clear if it’s OK for us to use it on this blog. We’ll also need permission from a parent or guardian to publish your name.
