Do assassin bugs really collect damar for its chemicals The resin serves their needs because it does not harden quickly but remains soft and sticky. Softness and stickiness are physical properties, but they are also direct consequences of the resin s chemical composition. It seems fair to credit the bugs employment of damar to its complex mix of chemicals. We could also ask whether green lacewing larvae appropriate aphid wool for its chemicals. In that case, the significance of chemical properties appears unequivocal, as the ants chemical sense evidently equates the waxy wool with aphids. 

GC-EAD analysis of thoracic extracts of the male green lacewing, Chrysopa nigricornis Burmeister, showed that two compounds elicited response from conspecific male antennae 1-tridecene and (li , 25, 5R, 8i )-iridodial. Iri-dodial also attracted males of the goldeneyed lacewing, C oculata Say, and to a lesser extent, C. coloradensis Banks males. 

The green lacewing fly Chrysopa flam lays its eggs on 1 cm silk stalks glued to the undersides of leaves. 

Green lacewings are prominent predators on organic farms in Iowa. 

Ladybirds start to feed on aphids as soon as they appear in the spring. The rather long yellow eggs are laid in aphid colonies. The larvae have small nodules on top and stronger legs but weaker mouth parts than green lacewing larvae. 

The adult green lacewings have interleaved wings of a green to reddish hrown colour.

ENEMIES. Under natural conditions the red spider mite has very many enemies and should therefore not be a major problem in organic production. By far the most important enemy is the predatory mite, but globe beetles, green lacewings and the anthocorid bug Orius minutus can also provide valuable assistance. Depending on weather conditions, in some years these predators can achieve control of spider mites even without the aid of predatory mites. 

Alternate food sources will help keep beneficial insects in your garden and are often necessary in order for the beneficials to reproduce. Some parasitic wasps, for example, lay more eggs after feasting on plant nectar. Green lacewings eat aphid honeydew to boost...
