Pond dipping
Exploring pond life by pond dipping can be great fun. If you don’t have a pond net, try
using a plastic carton to dip into your pond - you’re still sure to
find lots of creatures if you look carefully.
How to pond dip
Some creatures may be scared off by your dipping, so spend some time looking
into the water first. Put some clean pond water in a pot or tray. Sweep
with your net firmly and quickly, in straight lines, through the water,
plants and top layer of mud. Very carefully put the creatures in clean
water by emptying your net into it or gently lifting them out with a plastic
spoon. Don't hold any of the creatures with your fingers - in case you
hurt them or they hurt you - and make sure you always keep them in water.
Biological diversity
The biological diversity of a pond simply means all the different types
of animals and plants living there. A typical pond is home to an amazing
variety of animals and plants.
Food cycles
The plants and animals of a pond are all connected in a complex food
web.
This means that they all depend on each other - if any species is added,
removed or affected in any way there will be an effect on all others.
Plants are able to make basic foodstuffs from water and carbon dioxide,
using energy from the sun, in the process called photosynthesis. They provide
food for the plant-eating animals (herbivores). These are in turn consumed
by meat-eating animals (carnivores). Completing the cycle are those that
feed on waste and dead material (scavengers and detritivores).
Some animals eat a bit of everything (plant, animal and sometimes dead
material), we call these omnivores.
Larva or nymph?
We call the young one of an insect a larva if its species goes through
complete metamorphosis (egg to larva to pupa to adult) - e.g. butterflies,
beetles or flies. We call it a nymph if its species has an incomplete metamorphosis
(egg to nymph to adult, with no pupa) - e.g. bugs, dragonflies or mayflies.

Ponds are fascinating places, there is so much to learn about them.
