It has at least two generations with adults seen from May to October. The adult moths are tiny at about 4-5mm in length.

Infected leaves are covered in small brown patches which spread rapidly across the entire tree, giving an autumnal appearance. The Bucculatrix start feeding as leaf-miners, and then most species leave the mine as they develop to feed externally. ), ladybirds and lacewings found that none prey on C. The leaf-mining moth. YES I would buy it again, it does help control the pesky insect but its not a 100% cure. This micro moth has a forewing length of just 4mm and is bright orange with white chevron markings. Symptoms It is usually easy to spot trees affected by the leaf-mining moth, especially as the season progresses. [3], Cameraria ohridella causes significant damage, mainly late summer browning, to the appearance of horse-chestnut trees. But it's not the moth that actually does the damage, it's their larvae. [15] A synthetic pheromone can be used to trap males,[16] but effective control may be hard to thus achieve. I still had to pick off those leaves that did have larvae eating away. The vast majority of leaf-mining insects are moths (Lepidoptera), sawflies (Symphyta, the mother clade of wasps), and flies (Diptera), though some beetles also exhibit this behavior. These mines are formed by the larva (small caterpillars). Looking for a specific moth species? [10] This Balkan origin is further documented by numerous herbarium samples that date back to 1879. The horse-chestnut leaf miner was first observed in North Macedonia in 1984, and was described as a new species in 1986. Citrus leaf miner is a species of moth, the larvae of which feed on young citrus tree leaves by creating shallow tunnels that serpentine through each leaf and sometimes the surface of the fruit. Control possibility and additional information on the horse-chestnut leafminer, Gilbert, M., Grégoire J.-C., Freise, J. F., & Heitland, W. 2004. When attacking Quercus robur (English oak), they also selectively feed on tissues containing lower levels of tannin, a deterrent chemical produced in great abundance by the tree.[1].

Horse chestnut leaf-miner is a small moth with caterpillars that feed inside horse chestnut leaves, causing brown or white blotch mines to develop between the leaf veins. A number of projects have been launched to investigate the biology and biological control of Cameraria ohridella and its impact since 2001, for example, an EU-wide multidisciplinary project, CONTROCAM ("Control of Cameraria") and the HAM-CAM Project. [3] Of the 30 known mitochondrial haplotypes for the species[3][10] only three (known as A, B and C) have invaded the rest of Europe since 1989, and only A is dominant. When fully grown, the larvae will curl the leaf around for protection while they pupate. The mine often contains frass, or droppings, and the pattern of frass deposition, mine shape, and host plant identity are useful to determine the species and instar of the leaf miner. The horse-chestnut leaf miner (Cameraria ohridella) is a leaf-mining moth of the family Gracillariidae. Each female moth lays between 20 and 40 eggs singly on the upper surface of leaves, and once these hatch 2–3 weeks later, the larvae develop through five feeding phases (or instars) and two prepupal (spinning) phases before the pupal phase. [8][9], Cameraria ohridella was first noticed from outbreaks near Ohrid Lake, Yugoslavia in 1984, and was described as a new species by Deschka and Dimić in 1986.

The horse-chestnut leafminer was first collected and inadvertently pressed in herbarium sheets by the botanist Theodor von Heldreich in central Greece in 1879. A leaf miner is any one of numerous species of insects in which the larval stage lives in, and eats, the leaf tissue of plants. Find the perfect leaf miner moth stock photo. While feeding externally the larva eats out small windows in the leaf, generally from below, leaving the upper epidermis intact. By the third instar, the larva creates a mine approximately 8mm in diameter; this is further expanded by later instars until one mine can cover several square centimeters. The horse-chestnut leaf miner (Cameraria ohridella) is a leaf-mining moth of the family Gracillariidae. In early summer, the adult female lays up to 180 eggs on newly opened leaves. The lepidoptera maps on this website are updated using data from the Leaf-miner Moths Recording Scheme. When this occurs it may lead to high moth mortality as the larvae compete for space and food. This includes the common or European horse chestnut, or ‘conker’ tree ( Aesculus hippocastanum) , the most populous species of horse chestnut tree grown in the United Kingdom. [2] The pupae can be mistaken for pupae of the genus Phyllonorycter but can be distinguished because C. ohridella pupae do not have a cremaster and the first five abdominal sections have strong lateral spines on them.
