The order Hemiptera is a large group of insect that is known as the ‘True Bugs’. It includes the shield bugs, froghoppers, leafhoppers, aphids, cicadas, scale insects, mealybugs and water bugs. In total around 80,000 species have been recorded by science and they can be found everywhere there is land except the frozen areas near poles. All the true bugs feed through sucking mouthparts – while some such as cicadas and planthoppers, only ingest plant juices, many others are voracious predators. These include the assassin bugs ( Family Reduviidae ), of which there are around 7,000 species worldwide. The smallest true bugs may be less than 1 mm long, where as the largest ones may exceed 100 mm ( 4 inc ). All the true bugs are hemimetabolous, with tiny nymphs hatching from eggs. They then grow through a series of instars until they become sexually mature adults, complete with wings (if present in the species). While the vast majority of true bugs have to pair in order to reproduce, some are able to do so without mating.
