Bugs

Insects in the order Hemiptera are the 'true bugs'. They are unique amongst insects in having their mouthparts formed into a piercing beak or 'rostrum', used to suck juices from plants or other animals.   Their life cycles do not have a larval and pupal stage; instead, juvenile bugs have a series of nymph-stages or 'instars', which progressively have more adult-like characteristics. Hemiptera are divided into distinct sub-orders:

  • Heteroptera include the shield-bugs, plant bugs, ground bugs, water bugs and allied families.  These have a thickened and opaque basal part to their forewings, with a transparent outer part.  
  • Auchenorrhyncha are the leafhoppers, planthoppers, cicadas and allies. Some authorities divide this into two separate sub-orders: Cicadamorpha and Fulgoromorpha.  Many have enlarged back legs and can jump.
  • Sternorrhyncha are aphids, psyllids and allies.
