We then hunted for invertebrates in an overgrown area of the grounds and discovered many invertebrates including the following.
Small white slugs
Small black slugs
Some of the smaller invertebrates were observed using dinocams attached to laptops
We then explored the pond. Armed with nest the children collected some invertebrates from the pond to observe close up and discuss. This included the whirligig beetle that whizzes around on the surface film and pond skaters that also travel on the surface film. The whirligig beetles feed mainly on mosquito larvae and similar creatures while the pond skater specialises in feeding on insects that fall into the pond.
Lesser water boatman
Spider (on surface film - not seen close up)
We also observed frog spawn and juvenile sticklebacks.
We discussed the importance of ponds to wildlife in general. We discussed how many of these insects/larvae are transient, capable of travelling from pond to pond. They survive underwater with the aid of breathing tubes, gills or by carrying a bubble of air with them. Despite the weather everybody seemed to enjoy the day
