However, several peculiarities in the leafminer's biology and ecology, such as its inefficient control through natural enemies, indicate that it may be of exotic origin. Females lay eggs on the upper side of the leaves. Larvae develop through 3 instars in 1 … The eggs hatch 2 to 3 weeks later. First record of some mines on Aesculus hippocastanum in the park of Tervuren on 1999-11-16, leg. Cameraria is a genus of moths in the family Gracillariidae, which includes many species of leaf miners.One of the best known species is the horse-chestnut leaf miner, Cameraria ohridella.. First instars make a very short, epidermal galery on the upperside of a leaf, abruptly widening into a semi-circular blotch, light brown, darker brown at its centre. The horse-chestnut leaf miner is a leaf-mining moth of the family Gracillariidae. ... Because their brief life, larvae of the chewing type are somewhat difficult to find. <]>>

One important source of potential bias that we needed to consider was the apparent under-recording of C. ohridella's distribution in Britain in recent years.The year that C. ohridella had first been detected in a locality (specifically a 10×10 km square) since its arrival in Britain in 2002 was collated by Forest Research . There are usually three generations during summer, and, by August, the foliage may be extensively damaged, leading to early leaf fall. The horse-chestnut leaf miner overwinters in the pupal stage in a cocoon in dead leaves. From May until August the females lay their eggs along or near the lateral veins of the leaves on the upper epidermis. The pupa hibernates. The form with pink flowers is not accepted as a food source. See also gracillariidae.net and bladmineerders.be. Since then spread all over Belgium and most of the time in large quantities, thousands of mines per tree. A female can produce on average 20-40 eggs which Aesculus hippocastanum, Nieuwendam; head, dorsal and ventral, of the sap drinking stage.

Adults rest on tree trunks during day time. Abstract Horse chestnut trees in many regions of Europe have suffered from epidemic infestations of C. ohridella for more than ten years. Cameraria ohridella probably originates from remote natural stands of the European horse-chestnut, Aesculus hioppocastanum in Greece, Albania and Macedonia.

Very common in parks and lanes where Aesculus hippocastanum is planted, causing severe damage. In most cases there are several mines in 1 leaf and from July onwards, some leaves are completely covered with mines causing premature defoliation. The pupa is brown and is 2.9-4.5 mm long. The caterpillar hatches from a tiny egg, then spends its time eating and growing.

The horse-chestnut leafminer was first collected and inadvertently pressed in herbarium sheets by the botanist Theodor von Heldreich in central Greece in 1879. There is however, a similar-looking fungus which can cause confusion ( UKMoths ). This species was relatively described very late (1986) from SE Europe from where it spread westwards at a speed of ca 200 km per year.
