The psyllids or plant suckers are a group of sap

Sap is a fluid that circulates through a plant's vascular system, in a similar way to blood moving through our veins. Phloem sap carries the sugars produced in the leaves by photosynthesis down to roots and other storage organs, as well as carrying minerals and hormones. Xylem sap is watery and transports nutrients absorbed by the roots upwards to the rest of the plant. Some plants leak sap from wounds or pruning cuts, and this is known as bleeding. sucking true bugs (Hemiptera). There are more than 40 species found in Britain. A gallery and more information on these species can be found at .

Box sucker

Suckers are growths that appear from the root systems of many trees and shrubs such as lilac, cherries, Robinia. On grafted plants such as roses, suckers can grow from below the graft union, on the rootstock material. Suckers are usually removed by gently pulling off when young. feeds at the shoot tips of box plants in spring, damage is usually minor and can be tolerated.

Box is host to several invertebrate

Invertebrates are animals that don't have a backbone. Common garden invertebrates, or minibeasts, include insects, spiders, worms, slugs, snails, woodlice and centipedes. They play important roles in a garden ecosystem, including breaking down organic matter, pollinating flowers and providing food for other animals. species and suffers from a number of other problems .

• In April to May flattened, pale green, wingless nymphs live among the leaves at the shoot tips
• New shoot extension in spring can be stunted and the cupped leaves at the shoot tips produce a cabbage-like appearance

Damage from this insect is superficial and so it is not necessary to manage this insect especially on established box hedges or topiary plants that are going to be clipped. It is part of the biodiversity

• Often suckers do not affect the growth or vigour of plants and so should be tolerated
• Encouraging predators and other natural enemies of suckers, in the garden, such as birds , ladybirds , wasps and ground beetles will help keep damage to a minimum
• Regular clipping removes affected parts of the plant

• The nymphs excrete a sugary liquid called honeydew that is coated with a white waxy secretion from their bodies
• Yellowish brown winged adults, 2-3 mm long (1/8 in), develop in May to June
• No further damage occurs after June
