DescriptionTop of page
The morphology of the adult was addressed by Kumata (1963) and Kumata et al. (1983). The caterpillar chaetotaxy was described by Kumata (1993) and the morphology of the pupa was described by Gregor and Patocka (2001). The morphology of all the stages, including the larval chaetotaxy was studied by Sefrová (2002).
The egg is slightly elongated, ellipsoidal, and has a delicate pitting on the chorion surface. It is 0.32-0.37 mm by 0.23-0.27 mm. It is greenish-ochreous, which corresponds to the undersides of the leaves on the host plant.
The larval morphology corresponds to the morphology of other Phyllonorycter larvae. The larva is whitish-ochreous and is 4.0-5.6 mm long in the final instar. There are five larval instars. The first three instars are flat with reduced mouthparts and legs (sometimes called sap-feeding instars e.g. Kumata, 1978). The triangulate head capsule shows prognathy without spinneret, labial and maxillary palpi. There is a close group of stemmata on the head near the antennal base of these instars. The triangular mandibles with three curved cusps are moved horizontally between the huge flat labrum and the labium. The thoracic segments are strikingly dilated (especially in the first instar) compared with the abdominal segments. This characteristic decreases with the next instars. The final two instars (tissue-feeding instars) show the morphology of exophagous caterpillars. Their heads are more globular, semiprognathous and have complete mouthparts. The mandibles are more or less rectangular with five cusps on the frontal edge and they move vertically. The stemmata form a quadrangle. The thoracic legs, abdominal prolegs (on the third to fifth segments) and anal prolegs are normally shaped. The 23-38 claws of each proleg are positioned in multiple, usually irregular circles. The individual instars can be primarily distinguished according to the width of the head capsule: I: 0.14-0.16 mm; II: 0.18-0.21 mm; III: 0.25-0.28 mm; IV: 0.25-0.30 mm; and V: 0.31-0.40 mm.
The pupa is light brown to brownish-black and 3.2-4.0 mm long. Its frontal process is short and broad. It is in the shape of an equilateral triangle with distinct surface sculpture. Abdominal segments two to eight bear two pairs of rigid setae and their dorsal parts are covered with coarse thorns. The male genitalia only slightly protrude. The tenth abdominal segment is long, with a broad anal field. This has an elongate cremaster, which is round in ventral view, and elongate and strongly constricted in lateral view, with one pair of small hooked thorns at the end.
The wingspan is 6.3-8.3 mm. The adult exhibits distinct seasonal dimorphism. The aestival form has a whiteish-ochreous frons and labial palpus. The hair tuft on the head is ochreous with individual white scales. The antennae are greyish-white with black circles. The thorax is golden-ochreous, with three white lines. The forewing is golden-ochreous, with a long and narrow basal streak (occasionally indistinct), lacking a dark margin, or with individual dark scales only on its fore margin. The first (basal) transversal streaks are narrow and slope outwards. The dorsal streak is distinctly longer than the costal streak. The other three costal streaks are located close to each other before the apex. The second dorsal streak, which is before the tornus, occasionally fuses with a light tornal spot. The basal margins of all the streaks are more or less bordered with black scales. A distinct line of black scales divides the yellowish-white cilia. The hind wings and their cilia are pale grey.
The winter form (differences only) has a hair tuft on the head that is greyish-black or black with individual white scales, and is entirely white. The thorax is dark brown, and occasionally has white scales and white, indistinct lines. The forewing is grey, greyish-brown or greyish-black, mixed with white and brownish-black scales or spots. The ground colour of the winter form is very variable from pale grey to brownish-black. This striking habitual seasonal difference is possibly due to the fact that the hibernating individuals easily escape the attention of their predators in overwintering shelters. No sexual dimorphism has been observed.
DistributionTop of page
During the 1980s, P. issikii was found in Moscow and later in several other towns of Russia and Ukraine (Osipova, 1990; Kozlov, 1991; Mey, 1991; Orlinskij et al., 1991; Sefrová, 2002). It seems that the species was introduced from eastern Asia to Moscow or to other towns of the European part of the USSR. Anemochoric (air current) transportation from eastern Asia to Russia or a stepwise spontaneous spread through Siberia are not possible because its food plant, Tilia spp., shows no continuous distribution between eastern and western parts of the Palaearctic region (e.g. Dubatolov and Kosterin, 2000).
During the 1980s, P. issikii was also recorded in Kiev, and since that time it has spread to the west, via the north. It was first found in southeastern Poland in 1996, in Lithuania in 1997 (Noreika, 1998) and in Belorussia and Latvia in 1998, when it occupied a third of eastern Poland (Buszko et al., 2000; Buszko and Nowacki, 2000). In 1999, it had reached the eastern half of Poland. In 2000, the first mines were observed in the Czech and Slovak Republics (Sefrová et al., 2000; Tokár 2002), southern Austria and northern Hungary (Sefrová, 2002; Szabóky and Csóka, 2003). In 2001, the mines were observed in eastern Germany and Estonia, and in 2002, in Finland (Leinonen and Kaitila, 2003). The spread of this species continues in a west and southwest direction.

Biology and EcologyTop of page
Development of the summer generation is temperature-dependent and is usually completed in 4-7 weeks. In laboratory experiments at 25°C, the larvae develop in 13 days and the pupae develop in 6 days. At 20°C, the larva lasts 17 days and the pupa lasts 8 days. The development times of the individual larval instars are: I: 2-7 days; II: 2-8 days; III: 3-8 days; IV: 3-8 days; and V: 3-8 days.
The hibernating moths (dark winter forms) emerge after 10 August but generally only from the end of August and the beginning of September to 10 October. The pupae can also be recorded in the latter half of October. The complete development of this generation lasts 8-11 weeks. The leaf epidermis of Tilia spp. is very soft and thin so that it is easily disrupted and decays after the leaves drop. This is probably the main reason why the moths of this species hibernate after they emerge and before the leaves drop. The individuals of the summer and winter forms are dissimilar (cf. morphology).

Means of Movement and DispersalTop of page
P. issikii mostly shows a scattered distribution. There is no distinct boundary to its forward progression of dispersal. Long-distance dispersal appears to be on air currents. The adults are nocturnal and only move over short distances of upto 1000 m.
Movement in Trade
As with many other Phyllonorycter species, the dispersal of pupae in fallen leaves is impossible because the adults always emerge before the leaves drop. The transportation of eggs, larvae and pupae with the host plants is very improbable because lime plants (seedlings) are not evergreen and they are transported without leaves. The eggs and larvae can only survive in fresh living leaves. The adults hibernate in various crevices and other shelters and their passive transportation during hibernation in containers, boxes etc. is both possible and probable (Sefrová, 2002, 2003).

Prevention and ControlTop of page
Due to the variable regulations around (de)registration of pesticides, your national list of registered pesticides or relevant authority should be consulted to determine which products are legally allowed for use in your country when considering chemical control. Pesticides should always be used in a lawful manner, consistent with the product's label.It is possible that during the initial years of its spread, the population density of P. issikii may increase. However, the abiotic factors and the biotic antagonistic species, identical to those that regulate the densities of the related autochthonous taxa, may control this. This is demonstrated most efficiently by the fact that 10-20% parasitism of P. issikii, mostly by wasps of the superfamily Chalcidoidea, was observed during the first year of its discovery and up to 40% parasitism was observed in the following years. Chemical control or other control practices will probably be unnecessary.
