Insect eggs come in a wide variety of shapes, sizes and colours. Most are very difficult to find. You need to spend a lot of time peering underneath leaves of shrubs, herbaceous plants and grasses. Sometimes, the eggs are laid on top of grass stems or other vegetation. Most are found in clusters, but others are found singly. Exuviae or the shed skins of insects are also fascinating. Many are white, but some are transparent with patterns.
