Bugs Count!

30 June 2011

The new OPAL survey, Bugs Count, is proving to be very popular. We've just had over 200,000 bug sightings to our website, which is a great start! A lot of teachers, both formal and informal, are using the surveys to encourage their students to look closer at the natural world around them. The survey pack (download from http://www.opalexplorenature.org/bugscount or contact your regional OPAL team to see if they've got any physical packs left to send out) is brilliant and contains everything you need to do the survey, but it's sometimes useful to give pupils some background information about minibeasts before they do the survey, or to do some work afterwards to reinforce their learning. So, I thought I'd share with you a fantastic resource I've found on the internet. It's ClipArtETC: Florida's Educational Technology Clearinghouse (long name, great website). The images below are taken from it:

There are also pictures of plants, architecture, mythology, maths etc etc. They are mainly from out of print books. They can be downloaded and used free of charge, although they do limit it to 50 per project and it has to be for educational purposes.

Anyway, I think it's a great resource, hope you find it useful.

Scabs produced by plants...

Sorry for the large gap in posts, Chris (webmaster) and I have entered the world of twitter, follow us @OPALnature if you're into that kind of thing. Anyway, I went out with the Yorkshire Naturalists Union on Saturday to Spurn Point, a reserve managed by the Yorkshire Wildlife Trust . It's a spit, a long stretch of sandy beach created by the action of waves pushing sand along the beach and out into an estuary (in this case, the Humber). Anyway, I was following around Tom and Ian of the British Plant Gall Society and they opened my eyes up to a whole new world!

So, what's a gall? Well, here's an example of some galls we saw on Saturday.Robins Pin Cushion

The red furry looking blobs on this rose are called Robin's Pin Cushion, or Diplolepis rosae. These amazing growths are the rose's reaction to an external influence, in this case, it's caused by a tiny wasp. The rose forms a gall to protect itself, it's a bit like you getting a scab.

Although this is fairly common, look out for it next time you see a wild rose bush, Ian and Tom had never seen so many on one plant, so I was pretty happy with this find!
