Lily Beetle

Despite being viewed as a pest by many a gardener, for munching the leaves of their prized lilies, the lily beetle (Lilioceris Lilii) is a favourite insect of Andrew Salisbury, principal entomologist for the Royal Horticultural Society (RHS). In this short film Andrew tells us a bit about the lily beetle and why he finds it so fascinating.

Make a pitfall trap

Try out a new technique for finding insects with HOPE Learning Officer, Kate.

Have you found any interesting insects lately?  Along with the other HOPE Learning Officers, I have been out and about in Oxfordshire schools where we have found some fantastic insects.  Among my recent favourites is the thick-legged flower beetle, Oedemera nobilis

These beautiful beetles are distinctive with their stunning emerald-green colour and their chunky thighs which are seen only in the males.   We have also found lots of varied species of ladybird including cream spot, 14-spot and eyed ladybirds. Generally, we collect insects using sweep nets and beating trays but, of course, you might be lucky enough to find some interesting insects just by looking in the right places.  Under stones, logs, leaves, in amongst long grass or on flowers are all excellent places to start.  Insects, however, are very good at hiding so why not make a pitfall trap? This can be a great way to find a range of insects, particularly ground beetles.

Here are the written instructions.

You will need: 

  • A small pot such as a clean yoghurt pot
  • A trowel for digging
  • A few stones
  • A small piece of wood or a flat stone to act as a rain cover

What to do:

  1. Find a good spot for your trap on level ground, amongst vegetation.
  2. Dig a hole big enough to sink your pot so that it is completely level with the ground.
  3. Place the pot into the hole. You can put a few leaves, small stones and twigs in the pot to make any insects you catch feel at home.
  4. Build a cover over the trap by placing stones around the pot and resting a flat stone or piece of wood on top.  Make sure there is enough space for insects to crawl under.  This will stop the pot filling with water if it rains.
  5. Wait for a few hours or, better still, overnight.
  6. When you are ready, empty your pot carefully into a tray so you can see what has fallen in.  Take photos so that you can have a go at identifying what you have caught.
  7. Remember to check your pitfall trap every day and return any creatures carefully to a sheltered spot in vegetation.

Cartooning with Chris

Here at Crunchy on the Outside we love insects and we also love cartoons. What could be better, then, than cartoon insects?!

In this video Chris Jarvis shows us how to draw a mighty dung beetle called the Minotaur Beetle (Typhaeus typhoeus) complete with its own ball of dung!

Minotaur beetles grow to about 2cm in length and can be seen between September and July. They live in grassland and heathland with sandy soils. They feed on rabbit droppings and other dung (yum!) which they roll into balls and bury them in nests which can be over a metre deep underground. Male beetles may defend these nests using their long horns. The females lay their eggs in these nests. The eggs then hatch and the larvae feed on the tasty dung!

Watch the video carefully and you will see that Chris has included many of the key features of this fascinating beetle. He has deliberately left one insect feature out of his drawing. Can you spot what is missing? Here’s a clue: they help insects sense their environment.

Helen Roy’s Favourite Ladybirds

Professor Helen Roy, President of the Royal Entomological Society, tells us about a group of insects that interest her most: ladybirds. Also known as ladybugs, ladybirds are in fact beetles. In this video, Helen shares three of her favourites.
