Do One Thing

Summer Term 2008

The Do One thing this term is on minibeasts. On this page you will find a food web and Minibeasts Fact File to help you find out more about the minibeasts found in soil and leaf litter. New for March 2010 is a section on earthworms found in leaf litter and in the soil.

Minibeasts - a woodland food web

Here is an example of a food web for a community of animals that live in leaf litter. Click on the pictures to find out more about each animal.

Snail

Snails

  • Snails eat living plant material
  • When threatened, a snail can pull its body under its shell
  • Snails move very slowly (about 1mm per second) and leave a trail of mucus (slime) to help smooth out the way

Woodlouse

Woodlice

  • Woodlice are scavengers - they feed on dead or dying plant material and on their own droppings
  • They prefer damp places, such as under logs, because they breathe through gills (like fish) rather than through lungs (like humans)
Earwig

Earwigs

  • Earwigs are insects (they have six legs) and they feed mainly on plant material
  • Earwigs are nocturnal, and rest in shady crevices during the day
  • The pincers are used for many things such as climbing

Millipede

Millipedes

  • Millipedes have 80-400 legs each
  • They feed on dead plant material like fallen leaves
  • Their habitat is in leaf litter or in the soil
  • When threatened, they curl up into a tight coil
Ground beetle

Ground beetles

  • Ground beetles are insects (they have six legs)
  • Many types of ground beetles are predators, and feed by cacthing smaller animals

Beetle larva

Beetle larvae

  • A beetle larva is the young form of an adult beetle, like the ground beetle above (the life-cycle is egg - larva - pupa - adult)
  • The plural of larva is larvae (not larvas)
  • Beetle larvae have biting jaws and two tails
Wolf spider

Wolf spiders

  • Spiders are arachnids (they have 8 legs), not insects
  • Some spiders spin webs to catch their prey, but the wolf spider runs fast over the ground after its prey instead
  • Wolf spiders have excellent eyesight and can hunt both at day and at night

Earthworms

You may have seen me before, but how much do you know about me?
Thousands of us live beneath your feet but you don't even notice us.

I don't mean to brag, but in the soil world we are superheroes. Why not take a closer look...?

Earthworms may all look the same, but there are actually 26 different species in Britain. Some are common and found in lots of places while others are rare. If you find lots of earthworms in your soil it can be a sign of good soil quality. Earthworms can be sorted into 4 groups

  • red earthworms
  • stripy earthworms
  • pale earthworms
  • green earthworms

Why not download a recording sheet (pdf, 200kB) then look for earthworms where you live? Here are some of the earthworms that you might find.

Lob worm

Lob worm

  • A large fat red earthworm, always over 8cm long even when not moving.
  • Found in gardens and other grassy places all over Britain
  • Builds deep burrows, sometimes as deep as 3 metres in the soil.

Black-headed worm

Black-headed worm

  • A large thin red earthworm.
  • It has a dark head and often a paler tail
  • Builds permanent vertical burrows up to 60cm deep in the soil

Blue-grey worm

Blue-grey worm

  • A pale earthworm
  • Often has a yellow tail
  • Lives just below the soil surface
Compost worm

Compost worm

  • A stripy earthworm - longer and fatter than the brandling worm
  • Usually found in garden compost, leaf litter and manure heaps
  • Eats dead leaves, stems and other plant materials

Brandling worm

Brandling worm

  • A stripy earthworm - shorter and thinner than the compost worm
  • Usually found in garden compost, leaf litter and manure heaps
  • Eats dead leaves, stems and other plant materials
Chestnut worm

Chestnut worm

  • A red earthworm
  • Common and widespread
  • Lives in leaf litter and can be found in manure and under logs

Green worm

Green worm

  • A green earthworm
  • Very common and widespread
  • Lives in the topsoil, often among plant roots
Grey worm

Grey worm

  • A pale earthworm
  • Very common and widespread, living in the topsoil but rarely in leaf litter
  • The head end has a special colour pattern: pink-whitish-dark grey-orange
Redhead worm

Redhead worm

  • A red earthworm
  • Widespread species, living in the topsoil and leaf litter
  • Sometimes flattens its tail into a 'paddle' to help it burrow through the soil (lob worms can also do this)
Rosy-tipped worm

Rosy-tipped worm

  • A pale earthworm
  • Widespread, living in the topsoil and eats soil
  • The first 10 or 15 segments are rosy pink or pale pink in colour

FOR TEACHERS: A scientific investigation for KS2/3

Planning several lessons? Download the Teacher Guidance and Pupil Sheets for a complete investigation to compare the different kinds of invertebrates making up the community in the woodland canopy with the invertebrate community living in the soil and leaf litter below.
