BioInfo (www.bioinfo.org.uk) has 3,680 host/parasite/foodplant and/or other relationships for Exopterygota (earwigs, grasshoppers, stoneflies, true bugs, and other insects with wings developing externally) |
These insects have wingless juvenile forms (eg nymphs) which often look fairly similar to the adults, albeit with wings reduced or absent. Development from the juvenile to the adult form (metamorphosis) proceeds by a series of stages (instars) which (in the winged species) have increasingly developed wings leading to the fully-winged adult.
