| Hawthorn shield bug | | Hawthorn shield bugs (Acanthosoma haemorrhoidale) is a species in the order true bugs (Hemiptera), the suborder typical bugs (Heteroptera), the family shield bugs (Acanthosomatidae) and the genus Acanthosoma. It is one of the most common shield bug species i... | | |
| | The hawthorn shield bug often lives alone in forests, on trees in fields and in forest edges. They prefer hawthorn shrubs, hedges and rowan and are active from April to October. They live on plant juices, preferably from berries. Their larvae live off juices from the leaves. | | |
| | | The hawthorn shield bug reproduces once a year. The females lay their eggs on hawthorn shrubs. The larvae hatch in June and after shedding their skin five times, reach maturity in August. The adult bugs overwinter on the soil. | | |
| | Anomoia purmunda live in forests edges and are common in gardens. They are active from April to autumn. This species reproduces once a year.
The fertilized females of Anomoia purmunda lay their eggs in holes bored into the fruit of hawthorn. The larvae develop in the fruit and feed on it. In autumn they pupate and overwinter in the soil. | | |
| | Adult hawthorn shield bugs reach body lengths of 15 - 17 mm. Their heads have a pattern of black and yellow stripes. They have red to red-brown stripes on the wing covers which at the edge of the pronotum look like a triangle. This colouration acts as camouflage m... | | |

Due to their similarity in appearance, Elasmostethus interstinctus can easily be confused with hawthorn shield bugs (Acanthosoma haemorrhoidale). | | |
| | Elasmostethus interstinctus prefer to live in sunny habitats, where they can be found on deciduous trees and shrubs. They eat or suck out the juices from the flowers of beech, alder and hawthorn, and occasionally those of herbaceous plants near the ground.
The larvae of Elasmostethus interstinctus live from June to August. They reach their adult stage in September and then overwinter. | | |

| | Lace bugs feed solely on plants, either on individual plant species (monophagous) or on a limited number of plant families (oligophagous). This is reflected in the name of each species (hawthorn lace bug, sugarcane lace bug, avocado lace bug, azalea lace bug etc. ). Lace bugs sit on the flowers and leaf undersides of their host plants. These insects are rather inactive and mostly hide between plant’s hairs, spines or in deeper holes. When d... | | |

The females of the spring generation leave the soil in early May and lay their eggs, in June, on the leaves of different plants, such as cherry, pear, juneberry, mountain ash, hawthorn, quince, birch or roses. They scratch into the leaf tissue with their ovipositor, forming a small pocket in which a single egg is deposited. After 2 weeks, the larvae hatch and crawl sluggishly on top of the leaf and eat the tissue under scraping. T... | | |
