Glasshouse Leafhopper , Glasshouse Hopper , Greenhouse Leafhopper
Hauptidia maroccana is commonly known as Glasshouse Leafhopper. Leafhoppers are tiny insects which suck the sap from plants. Glasshouse Leafhoppers are highly general, feeding on a range of glasshouse plants. They're not detrimental to plant health unless present in huge numbers. More severe problems arise more from the transmission of plant pathogens, because leafhoppers are vectors for disease, moving pathogens between plants as they feed.
Potential disease transmitter.
A food source for many small predators.
Adults: The adults measure roughly 0.3 cm. They're pale yellow-green with faint brown diagonal stripes on the back. These leafhoppers strongly resemble the closely related genus Arboridia. However, the glasshouse leafhopper possesses two black spots on the top of the head. The brown streaks on the forewing are less pronounced than that of Arboridia.
Coarse pale mottling produced on the upper leaf. Leaf yellowing. Leaves may dry and fall from plants.
Removing any visible eggs by hand. Diatomaceous earth sprinkled on leaves and around plants can be effective barriers against nymphs. Provide insect habitats around the garden to help keep the beneficial insects in. These can include anything from deadwood, shrubs, climbing plants and hanging baskets. Try to allow bits of the garden to 'grow wild' and cut back and mow less. Insecticidal soaps can be applied as infestations become heavy.
Systematic or contact insecticides can prevent heavy infestations. Organic sprays can be effective if applied frequently. Always read bottle instructions before applications. Never apply when plants or those surrounding are in flower.
