The series of annual compilations of remarkable records of Microlepidoptera is continued for the 31th year.

The winterstarted early with snow in Scania already on 19th October(2002) but then continued more as usually in south Sweden with mild weather, except in February, when hard frost on snowless ground occurred accasionally. Spring arrived at normal time but was rapidly followed by summer weather throughout June-August. The summer was usually warm and dry, though not as extreme as in 2002. Hoeever, the moth supply dimished rapidly already in July which is difficult to explain. Possibly the weather was too fine. More miners were also more or less absent during the autumn, following the decline previous year, but with remarkable local excetions. Again the winter appeared early with -10°C at Kristianstad already on 24th October and this month was even colder than the following November.

In spite of the cold spell, larvae and puae of Phyllonorycter platano (Staudinger) had survived in their mines. Two species are reported new to Sweden: Cameraria ohridella (Deschka&Dimic, 1986) found as numerous mines, and Herpetogramma licarsisalis (Walker, 1859), collected already in 2000. The unknown Monocroa species (reported by Svensson 2000) has to be deleted.

At present 1689 species of Microlepidoptera are known from our country.

The series of annual compilations of remarkable records of Microlepidoptera is continued for the 30th year.

At least in south Sweden the winter was short and mild. In the north summer appeared exceptionally early - e.g 27º C at Karesuando 31st May - but soon the weather went more normal but many of the June-July moths were already gone. A very warm and dry period came from the south 10th July and spread almost all over the country and continued with a short break 22-26 July into September. Probably the drought was to blame, as fewer and fewer moths came to light from August on, also nights with temperatures around +20º C. As autumn approached, warm eastern winds brought many immigrants to the south-eastern provinces but not in such great numbers as in the previous year.

Three species are recorded new to Sweden: Zelleria oleastrella (Millière, 1864), Coleophora jaernaensis Björklund & Palmquist 2002 and Eucosma metzneriana (Treitschke, 1830).

At present 1688 species of Microlepidoptera are known from our country.

Remarkable records of Microlepidoptera in Sweden 2001

The series of annual compilations of remarkable records of Microlepidoptera is continued for the 29th year. Like in the previous year lepidopterists experienced low or absent occurrence of many species in spite of mostly favourable weather.

This was obvious especially during a warm and dry period in July. A few immigrants arrived already in July and August, but the great influx occurred after the middle of September with a maximum about the 22nd continuing far into October and probably in at least two waves.

Nomophila noctuella was exceptionally abundant, but also Loxostege sticticalis, Euchromius ocellea, Udea ferrugalis and Palpita vitrealis were seen in numbers probably not observed before. At least N. noctuella and E. ocellea reached the northernmost parts of Sweden but remarkably almost no immigrants were seen in the south.

Six species are recorded new to Sweden: Elachista geminatella (Herrich-Schäffer,1855), Scrobipalpa pauperella (Heinemann, 1870), Cnephasia alticolana (Herrich-Schäffer, 1851), Selania leplastriana (Curtis, 1831), Thaumatotibia leucotreta (Meyrick, 1913) and Phycitodes lacteella (Rothschild,1815).

Elachista regificella, Sircom, 1949 has been misidentified and the Swedish species is E. tengstromi Kaila, Bengtsson, Sulcs & Junnilainen 2001.

At present 1685 species of Microlepidoptera are known from Sweden.

Remarkable records of Microlepidoptera in Sweden 2000

The series of annual compilations of remarkable records of Microlepidoptera is continued for the 28th year. Probably owing to declining populations of small moths preceding year and abnormal weather in this year most Swedish lepidopterists got diminutive results despite normal collecting efforts.

Some parts of Sweden are still less investigated and there quite a few species new to these provinces were recorded. On the other hand, no species was found new to the country and many normal immigrants were scare or not seen at all in spite of predominant warm winds from the south and south east during the usual migration autumn months.

Bryotropha mundella (Douglas, 1850) has recently been with synonymiesed with B. umbrosella (Zeller, 1839). The Coleophora and Monochroa species dealt with preceding year, are still without names.

At present 1679 species of Microlepidoptera are known from Sweden.

Remarkable records of Microlepidoptera in Sweden 1999

The series of annual compilations of remarkable records of Microlepidoptera is continued for the 27th year. Presumably due to unfavourable weather during the preceding season populations of moths were small or absent. Even though the summer and autumn of 1999 were unusually warm, especially in the south-eastern part of the country, gradually fewer and fewer moths appeared, except for immigrants. Drought could be the reason in some regions, but e.g. Gothenburg had the highest June precipitation ever measured. In spite of the reduced populations more interesting species were found than in many years.

New to Sweden are Ectoedemia decentella (Herrich-Schäffer, 1855), Phyllonorycter leucographella (Zeller, 1858), Acrolepiopsis betulella (Curtis, 1838), Schiffermuelleria schaefferella (Linnaeus, 1758), Coleophora maritimella ,(Newman, 1873), a possibly undescribed Coleophora species, a possibly undescribed Monochroa species, Etiella zinckenella (Treitschke, 1832) (collected in 1960, probably introduced and not established), Ancylosis oblitella (Zeller, 1848) and Homoeosoma nebulella (Denis & Schiffermüller, 1775) (first specimen in 1998, followed by an invasion in 1999).

Totally 1680 species of Microlepidoptera are now known from Sweden.

The series of annual compilations of remarkable records of Microlepidoptera is continued for the 26th year. Most collectors complained of a bad season owing to a late spring followed by rainy and cold weather during most of the summer. Northern Sweden was an exception with warmer and drier weather in periods. Probably the development of the different stages was affected by the hot and dry August and an unusually early winter spell the year before. However, six species can be added to the Swedish list: Digitivalva valeriella (Snellen), Coleophora cornutella (Herrich-Schäffer), Scrobipalpula diffluella (Frey) (recently separated from S. psilella (Herrich-Schäffer)) Lobesia virulenta Bae & Komai (recently separated from L. reliquana (Hübner)), Duponchelia fovealis (Zeller) (considered accidentally introduced) and Synclera traducalis (Zeller) (considered an exceptional immigrant from far away). Totally 1670 species of Microlepidoptera are now known from Sweden.

Remarkable records of Microlepidoptera in Sweden 1997

The series of annual compilations of remarkable records of Microlepidoptera is continued for the 25th year. Collecting season was somewhat disappointing, probably mostly owing to a late and cold spring. The summer appeared late, mainly in August. The hot and dry weather apparently resulted in the absence of many small moths, the pupae or even the moths possibly suffering from drought. Even migrating moths were scarce.

In spite of this, four species can be added to the Swedish list: Opogona omoscopa (Meyrick) (considered accidentally introduced), Phyllonorycter pastorella (Zeller), Coleophora spiraeella Rebel, reared from cases found in the autumn 1996, and Epermenia falciformis (Haworth), collected already in 1988. Some Tortricidae species, published new to Sweden recently (Witzgall et al. 1996), are not accepted, being unsatisfactorily verified. Totally 1664 species of Microlepidoptera are now known from Sweden.

Remarkable records of Microlepidoptera in Sweden 1996

The series of annual compilations of remarkable records of Microlepidoptera is continued for the 24th year. The weather in 1996 was probably not favourable for the hibernation of some stages of the moths, the winter and spring with some cold spells that at least made great damage to the flowers of hazel and pear in southern Sweden. The early collecting season was then about a month late owing to an abnormally cold spring though interrupted by a couple of days with summer temperatures at the end of April. The real summer did not start until the end of July and lasted for a month. On the whole the mean temperatures of the year were a little below normal in the southern part and a little above normal in the northern part of the country. The warm periods in August and also in September with winds from south-east favoured immigration, these events made 1996 the second best year ever, after 1995, for migrating microlepidoptera. Three species were found new to Sweden in 1996: Nemapogon falstriella (Haas), Caloptilia hemidactylella (D&S) and Blastobasis decolorella Wollaston. Phyllonorycter heringiella (Grønlien) is reinstated as a separate species. Totally 1660 species of Microlepidoptera are now known from Sweden.

The series of annual compilations of remarkable records of Microlepidoptera is continued for the 23rd year. The weather was favourable most of the year for collecting and probably also for the moths. A short warm period appeared already in April, followed by normal weather until the middle of July, when another warm period came, lasting a month though probably too dry for many species to thrive. Periods of southerly and easterly winds in the autumn were obviously favourable for immigration. Nomophila noctuella (Denis & Schiffermüller), Euchromius ocellea (Haworth) and Udea ferrugalis (Hübner) were found in larger numbers than previously reported ever. Also Plutella xylostella (Linnaeus) was very numerous, though decreasing after the summer. One Palpita unionalis (Hübner) and some Loxostege sticticalis (Linnaeus) were also collected. Three species were found new to Sweden as occasional immigrants or introduced: Nephopterix angustella (Hübner), Phthorimaea operculella (Zeller) and Opogona sacchari (Bojer). Biselachista occidentalis (Frey) published as Swedish (Traugott-Olsen 1994) is rejected. Totally, 1656 species of Microlepidoptera are now known from Sweden.

The series of annual compilations of remarkable records of Microlepidoptera is continued for the 22nd year. The weather of 1994 was fairly normal, except for an extremely warm July with temperature maxima over 30*C from some places and almost no rain in southern Sweden. In central Sweden then the first 10-20 cm snow arrived already on October 4th. In spite of the mostly favourable weather only one species was found new to Sweden, Recurvaria nanella (D&S), and no new immigrants appeared. A few species with extra generations were noted. Totally, 1653 species of Microlepidoptera are now known from Sweden.

The series of annual compilations of remarkable records of Microlepidoptera is continued for the 21st year. The weather was normal in most parts of Sweden as to temperature and precipitation, on an average. In reality it was most abnormal. The winter was mild as it has been in the last five years. The summer appeared already at the end of april with the highest temperatures of the year in many places. The warm and very dry period continued for a month and then the rest of the year was colder and wetter than normal. As a result of the weather conditions almost all interesting finds were made in the first half of the year. Three species were found new to Sweden, Argyresthia trifasciata (Staudinger), Cydia grunertiana (Ratzeburg) and Cydia molesta (Busck). A possibly undescribed Athrips species collected in 1992 and 1993 is recorded. Contrarily, Monochroa brundini (Benander) is sunk to a synonym of Aproaerema anthyllidella (Hübner) and Schiffermuelleria schaefferella (L.), Celypha flavipalpana (Herrich-Schäffer) and Homoeosoma nebulella (Denis & Schiffermüller) are considered not found in Sweden. Totally, unchanged 1652 species of Microlepidoptera are known from Sweden.

The series of annual compilations of remarkable records of Microlepidoptera is continued for the 20th year. In southern Sweden there was once more a mild winter followed by a warm summer with an extremely dry period lasting 2-3 months from the middle of May. On the contrary the month of October was colder than ever measured in some parts of the country. In the north the summer was mostly rather cold. Generally, collecting was not as good as expected, especially in the late summer and autumn. The only species new to Sweden, Leucospilapteryx omissella (Stainton), was recorded from empty mines. Another species, Agriphila latistria (Haworth), was found already in 1991 but not recognized until later. Two new species were described from Sweden lately, Bactra suedana Bengtsson 1990 and Monochroa inflexella Svensson 1992 (previously recorded as Monochroa species). Totally 1652 species of Microlepidoptera are now known from Sweden.

The series of annual compilations of remarkable records of Microlepidoptera is continued for the 19th year. Contrary to 1990 the weather was probably not favourable to the early stages of the moths, with a mild winter ending in a cold period continuing all the spring and early summer. In the province of Värmland there had never been measured a lower mean temperature of June. As a result collecting was usually unsuccessful until a warm period in July, then again rapidly decreasing. Only two species were found new to Sweden in 1991: Phyllonorycter platani (Staudinger) and Ethmia terminella Fletcher. Three more species were found already in 1990 but determined later: Stigmella sakhalinella Puplesis, Yponomeuta rorrella (Hübner) and Cydia amplana (Hübner), resulting in that year being one of the best ever. Totally 1649 species of Microlepidoptera are now known from Sweden.
