Celebrating Entomology with Children!

The Amateur Entomological Society's (AES) Bug Club is a great club for bug mad children between 5 and 17 years old. Extremely reasonably price at a annual subscription of £12.00 per child. www.amentsoc.org/bugclub/ The Bug Club organizes loads of events throughout the year and they are all well attended. Its a great way to help your child meet like minded friends and build their confidence with lots of opportunities to produce exhibits, give talks and have articles published. The children are always delighted to see their work published in a magazine and you get to keep it forever (after showing the grandparents)! Amongst all the events on offer there is also the chance to go away on field trips. These are very exciting trips for the children as they include going out at night to check traps and see moths, pond dipping and pinning workshops. Expert and well known entomologists are a constant presence as are other suitably qualified and CRB checked adults. The knowledge and encouragement these children receive is exceptional. It is the sort of experience that will stay with them for life and they might even make life long friends!

Using the bug hoover is always fun!

Tremendous Trade Fair!!

Get ready for the Amateur Entomological Society's (AES) Annual Exhibition and Trade Fair at Kempton Park Racecourse TW165AQ. Saturday 6th October 2012, 11am - 4.30pm. This is a fantastic entomological show to go to and the largest in the UK! There will be rows upon rows of traders and societies. It is open to everyone to attend - you do not need to be members- and at £4 per adult, £2 per child (under 7's free) pay on the gate, it is good value as a day out. There is simply so much to see, buy and learn on two levels of the exhibition building that you will be blown away! It is stuffed full of books, equipment, livestock, specimens and food plants. If your child is a member of the AES Bug Club they can enter a invertebrate based exhibit and with prize money on offer it is worth doing!! Come along and enjoy a tremendous day out meeting fellow enthusiasts and feasting your eyes on some of the worlds, as well as the UK's, amazing invertebrates! www.amentsoc.org/events/exhibitions.html

Learn about and admire invertebrates. Be inspired and meet like minded people at the AES Trade Fair 2012

Winter in waiting

Before the Autumn has time to prepare us for winters grip think about helping our overwintering invertebrates. They have had a very bad year this year with the continuous extremes of wet and cold weather so the over wintering population is more precious than ever. Leaving old assorted tree logs in a sheltered place is fantastic as is making an insect tower from wooden pallets stuffed with various mediums (see an earlier blog entry). If you do not have the space for either you can buy various different small insect houses from places like garden centers. You can also make something cheaper at home with your children or at school with your class. Invertebrates require shelter to protect and hide themselves in. Natural materials work best such as sticks, tree bark, straw and leaves to name but a few. There will need to be tiny gaps so the invertebrates can get in and move around so do not pack your materials in too tight. You will need a net to keep everything together and a roof as well as a base to protect the 'house' from deterioration. It is so easy and fun that the children will love to build their own - remember to put them somewhere sheltered such as  under a hedge, bush, behind the garden shed or greenhouse. Many of the insects you are helping to overwinter will be beneficial in your garden next spring too!

Using Birch log rounds, dark green plastic garden mesh, moss, leaves and bark these children have made tiny habitats ideal to help overwintering invertebrates. The mesh was attached using a staple gun. The children learnt about habitats, materials, insects, design and craft - they also all got something to take home (including pride in their project) - fabulous!

On the subject of . . . . . .

I have been really busy with schools recently especially as this is the 'minibeast term' for many primary schools. I only wish I could remember all the things I hear during my visits to the foundation years in particular! The children are fantastic and I always try to encourage discussion because I believe it helps the learning process. Below are a few that have actually stuck in my mind and made me inwardly chuckle.

"Can anyone tell me the name of a minibeast they have found?" "Nits."

"Luke is a snail. His shell is part of his body just like your finger nail on your finger. If you hurt his shell he could die." "No he couldn't." "Yes he will because it is part of his body." "No he wont." "Look here and you can see where his shell is joined to the soft part of his body. So if you break his shell you really are hurting him and he really could die." " No."  "Yes he will poppet." "No he wont cause he'll be a slug."

"This is a really, really cool insect. She curls up her bottom, that we call an abdomen, and holds out her front legs to look just like pincers. She is pretending to be a creature you can find in the desert, and that can kill you with the venomous sting at the end of its tail. What do you think it is that she is trying to mimic?" "A lobster."

"Some insects go through an amazing change as they grow up. Can anyone here tell me how a caterpillar changes into a butterfly?" "My mum says she wants to change our dad cause he wont grow up."
 
"Does anyone know what a larva is?" "Oooh yes, yes!! . . . . It comes out of mountains!"

Often the joy of working with young children is just listening in to their views of the world around them. There is a hidden danger lurking around every corner of discussion though. The importance of the Tooth Fairy and the very sad (and often very graphic), demise of the hamster are awesome subjects but not always directly related to the topic of the day. The trick is turning it, as quickly and painlessly as possible, back on to the main subject before they all have time to get going on rapidly digressing views!

A child's eye often sees the things we adults do not. Listening to their descriptions gives you a good idea of how much they understand and evaluate the subject you are trying to teach. There is often plenty to make you smile as well!

Pupa, Chrysalis or Cocoon?

Invertebrates go through two types of growth stages. One is called incomplete metamorphosis. This is when the invertebrate undergoes little, or no difference, as it matures into an adult. Grasshoppers are a good example. The young (nymphs) look identical to the adults except at the very last exoskeleton moult (instar). They then develop a usable set of wings. Some stick insect species never experience any change other than size as they mature, but a few do produce wings (sometimes these are only vestigial ). Then we have my favourite, complete metamorphosis. This is the really amazing one! The embryo becomes a larva then pupates into the adult (imago). The pupa is where all the body change is going on and I like to think of it as a mould, as it usually shows all the features of the adult yet to emerge. In the Lepidoptera order (butterflies and moths), the pupa is referred to as a chrysalis. The duration inside the pupa depends on the species and the climate. The cocoon is the casing around the pupa that some, but not all, species choose to make. Some beetle species make a cocoon out of the substrate around themselves. Some moth species spin the most incredible silk cocoons. Whatever they look like, the cocoons are simply made to help protect and camouflage the pupa. Just fantastic!

Oxfordshire goes wild!!

Have the most brilliant day out with your family at the Oxford University Museum of Natural History on Saturday 21st April 2012 from 12 to 4pm. This is such a fantastic day on many levels. Its free - that is always a good start! There are going to be loads of organizations there that specialize in the amazing natural world around us. You and your family can take part in lots of practical projects and even take some home with you. Best of all it is hosted by the Museum http://www.oum.ox.ac.uk/  itself. Bursting at the seams with great displays and awesome exhibits, all set in the most incredibly beautiful building. What a fabulous way to spend your day when the April showers are in full swing and you want to get excited about our stunning countryside. Remember, finding out things and learning together is sharing the experience. That really does bond you together as a family. Have fun!

Natural History Museums always seem to be in the most incredible buildings.

Oxford's is no exception. The stone, the carvings, the iron work, the vaulted glass roof.........

What is in a name?

Creepy crawlies, minibeasts, bugs, insects, invertebrates. So many names are used to describe the life forms that live in and around the under growth. Minibeasts is favored by schools especially pre-school and primary. Insects is not a true term as the word insect means 'cut into' and refers to only those with six legs. Spiders have eight legs and are Arachnids, Millipedes with their many legs are Myriapods and so the list goes on. All of which are actually are members of the Arthropod phylum, the biggest animal group on the planet. Invertebrate means a life form without a back bone and therefore includes creatures such as crabs and lobsters who are Crustaceans and also Arthropods. That leaves us with creepy crawlies, (not keen on that as it sends out entirely the wrong message) and bugs. Bugs is a well rounded word. It does not do anyone an injustice and actually has a rather friendly feel to it, partially thanks to the film Bugs Life. What name do I use? Well I tend to refer to my collection as invertebrates or inverts for slang. It is slightly more scientific than bugs and also it embraces a wider range of creatures. I am certainly not adverse to using the words bugs or minibeasts, but I definitely do draw the line at creepy crawlies or critters!!

A Shield Bug. The perfect name - a bug with a body that is shaped like a shield.
