Friends and Foes - Friends

Like it or not you will find that any number of uninvited guests find their way into your garden. This quiz deals with those that should be welcomed with open arms.

Robins, wrens, ladybirds, hedgehogs and lacewings will undoubtedly be loved by everyone. The ladies might not get on quite so well with the frogs, toads and worms and everyone should be a little wary of the bees and wasps but...... all of these will be tirelessly working to help protect your precious crops.

Any of the images can be clicked to enlarge them. Enjoy.

  • Males grow to about 8cm long but females can be nearly double this.
  • Skin can be light green, dark brown or a multitude of other colours between these two extremes.
  • They use their sticky tongues to catch insects, spiders, slugs and worms.
  • Can secrete a foul tasting substance called bufagin which deters potential predators from eating them.

People were treading on them

  • Family: Erinaceidae.
  • Work tirelessly through the night to rid your garden of insects.
  • They will also eat frogs, grass roots and berries.
  • They are particularly fond of melons!
  • If you want to feed them put out tinned cat or dog food and NOT bread and milk because milk might harm them.
  • If you have a pond then make sure there is a plank or other object that they can climb on to escape if they accidentally fall in.
Initially they were killed but because of international outrage they are now trapped and released on the mainland
4.

New Zealand Flatworm
New Zealand Roundworm
Australian Flatworm
Australian Roundworm
  • Order: Haplotaxida.
  • Not the prettiest of friends but extremely valuable nonetheless!
  • Earthworms play an important role in helping to convert leaves and other large pieces of vegetable matter into chemicals that can be used by plants.
  • Constant burrowing helps keep the soil aerated.
  • It is estimated that between 50,000 and 250,000 worms per acre can be found in fertile soil.
The New Zealand Flatworm has no natural predators in the UK and it eats our own indigenous worms.
5.

  • Constantly gathering and eating harmful insects from the garden.
  • On moonlit nights they can sometimes be found working overtime!
  • Very territorial so you are unlikely to see more than one in your garden.
  • Friendly creatures that like to be close at hand when soil is being turned over.
  • Can become tame enough to eat out of your hand.

Very humid autumns
Very cold winters
Very rainy springs
  • Latin Species: Troglodytes troglodytes.
  • One of the smallest British birds, our commonest breeding bird (according to the RSPB) and one of our most loved garden creatures.
  • Weighs about the same as a £1.00 coin!
  • They ceaselessly flit around ridding the garden of insects and spiders.
  • Flies very fast and very straight.
  • Has a surprisingly loud voice for such a tiny bird.
8.
What percentage of drone wasps survive the winter?
Zero
Between 1% and 5%
Between 6% and 50%
Over 50%
  • Order: Hymenoptera.
  • Wasps pollinate flowers in the same way that bees do and they are equally valuable for this.
  • Queens emerge from hibernation in the spring and build nests in underground holes, trees and wall cavities.
  • During the early summer wasps collect many insects to feed to their larvae.
  • They rarely sting unless they are frightened - don't flap your arms around!
Drones are not produced until late in the summer. They mate with virgin queens and then die before the onset of winter.
9.
What will make a worker bee develop into a fertile queen?
Smothering with royal jelly
Feeding with royal jelly
Hitting with royal jelly
Removing royal jelly
  • Order: Hymenoptera.
  • This picture (click to expand) clearly shows how bees help pollinate plants.
  • The bright yellow particles on the bee is pollen.
  • Queens control their hive by producing various complex chemicals that 'instruct' the workers what to do.
  • The keeping of bees is known as apiculture.
  • Both honey bees and bumblebees are in decline and gardeners are urged to do everything possible to protect them.
10.
How do frogs breathe?

Through gills
Only through lungs
Only through their skin
Through both lungs and their skin
  • Order: Anura
  • Much like toads, the skin colour of frogs varies considerably.
  • They can be yellowish, greenish or brownish!
  • Frogs have smooth skin (toads skin is often blemished).
  • Adult frogs feed on land whilst immature and young ones sometimes feed in the water.
  • They eat many insects (mainly at night) that might otherwise be troublesome to gardeners.
It is the ability to breathe through their skin that allows frogs to hibernate underwater
