A coloured rating followed by an exclamation mark denotes that different ID difficulties apply to either males and females or to the larvae - see the species page for more detail.

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.

Leafhoppers, planthoppers and allies (Auchenorrhyncha)

The Auchenorrhyncha are split in two sections: Cicadomorpha include froghoppers (Aphrophoridae and Cercopidae), leafhoppers (Cicadellidae), treehoppers (Membracidae) and cicadas (Cicadidae); Fulgoromorpha are the planthoppers (Delphacidae, Tettigometridae and Issidae) and lacehoppers (Cixiidae).   Unlike the Heteroptera, the forewings are not divided into two parts, but may be hardened or membraneous.  Coloration and extent of markings can be very variable, especially on the vertex and frons ('nose' and face) and the pronotum and scutellum.  Leafhoppers, planthoppers and froghoppers can jump strongly, using powerful hindlegs.  Many species have short- and long-winged forms (brachypterous and macropterous); long-winged individuals can fly and may travel long distances, allowing dispersal and colonisation of new areas.    They do not have a pupal stage in ther lifecycle; the immature forms or nymphs pass through several instars, each increasing in size and adult characters before becoming adults. 

They feed exclusively on plant sap, using their sucking mouthparts.  Many species feed on a specific plant species, or a narrow range of hosts.  This can help identification and with targetting surveys, and it is recommended that the host plant is always noted in your record.   Feeding in the UK can cause minor damage to plants - the characteristic stippling of leaves of roses, for example - but they can be serious economic pests in other countries.   

Many species show sexual dimorphism - the males and females are different in size and coloration.  Identification of some species can be very difficult, often involving dissection of the male to examine the internal genitalia - the aedeagus and parameres. The 'aedeagus' is a chitinious structure, often of very complex shape, analogous to the penis in mammals.  The 'parameres' are also known as the anal styles or claspers.  Females are often more difficult to identify, and are sometimes impossible.

Cixiidae - lacehoppers

The Cixiidae or Lacehoppers are one of the four families in the Fulgoromorpha.  They have membraneous and transparent wings, with prominent veins, and keels on the pronotum.
