oblast’, 11122, Ukraine
Abstract
Twenty-eight Odonata species were recorded in the Poliskyi Nature Reserve
(Zhytomyr oblast’, North Ukraine) in 2006 and 2007, 18 of which were reported
for the first time from this location. This included such rare species as
Somatochlora arctica (second record in the Ukraine, first record for 100 years),
Leucorrhinia dubia, Leucorrhinia rubicunda and Leucorrhinia albifrons. A breeding site and a dense population of Nehalennia speciosa were found in a bog
near the river. Zholobnytsya. The record of Orthetrum coerulescens is the
northernmost in Ukraine.
Introduction
The Poliskyi Nature Reserve is situated in the northern part of the Zhytomyrska
Oblast’ at the border with Belarus (Fig.1). Its geographical coordinates are
51°31’N 27°56’E (main area); 51°34’N 28°05’E (northern area near the river
Zholobnytsya). The reserve covers 2,145 ha and includes the territory of the
Selezivka, Kopysha and Perga forests. It is a typical wetland complex situated in
one of the most extensive bog and swamp areas of Europe – Polissia. The area
includes mires and bogs (called “Miroshi”) and transitional mires and fens in
floodplains of the small rivers Zholobnytsya and Bolotnytsya. Bogs are oligotrophic and represented by pine-Sphagnum communities, transitional wetlands
by mesotrophic pine-birch and bush-sedge-Sphagnum communities. Fens are
represented by eutrophic reed, sedge, and forest communities (Targonsky et al.,

2005). In 2004 the Poliskyi Nature Reserve was designated a wetland area of
international importance in Ramsar List.
The first data on the Odonata of Poliskyi reserve were reported by V. Nadvorny
during his entomological field work in 1976 and 1988. As a result, 14 Odonata
species and information on their habitat preferences, distribution and flight
season were revealed (Nadvorny 1996). Later, Ye. Vorobyov reported one new
species for the reserve (Vorobyov 2005).
Methods
In August 2006 and May and June 2007 dragonflies were collected in the eastern part of Poliskyi Nature Reserve, in the Selezivka forest (Fig.1). Clearings and
roads in the forest were surveyed as well as mires, oligotrophic and mesotrophic peat bogs and flood-plains of the rivers Zholobnytsya and Bolotnytsia.

Figure 2: Forest vegetation of mires.
Vaccinium myrtillus, a considerable part of the mires is overgrown with Betula
pubescens and Alnus glutinosa, occasionally with Populus tremula, Pinus
sylvestris (Fig. 2), or green and Sphagnum mosses (Fig. 3), bushes of Salix lapponum, S. myrtilloides and S. rosmarinifolia. In some places Oxycoccus palustris
and cotton-grass Eriophorum vaginatum occur (Fig. 4). Plant communities
mainly consisting of Nymphaea candida and Nuphar lutea occur in open water
places (Fig. 5).

Odonata of the Poliskyi Nature Reserve, Ukraine
Coenagrion lunulatum (Charpentier, 1840)
Previous records: common everywhere in May-July (Nadvorny 1996).
Despite Nadvorny´s record the situation remains unclear because there is currently no dense population of this species known in Ukraine and was nowhere
regarded as “common” in Ukraine (Gorb et al. 2000) or Europe (Dijkstra &
Lewington 2006). Perhaps the species identity refers to C. hastulatum which
looks similar and was more frequently observed (see below).
Coenagrion puella (Linnaeus, 1758)
Previous records: common everywhere in July-August (Nadvorny 1996).
Our data: Drainage ditches along the road, puddles, r. Zholobnytsya, bog

Our data: puddles along the road, lakes in forest, r. Zholobnytsya, bog around
r. Zholobnytsya, 14.05.2007, 23.05.2007, 12-13.06.2007 not abundant.
Surroundings of reserve, lake in the Bigun forest, 11.05.2007, 4 males, 3

bog with open water sur face, abundant sedges, Carex spp. and surrounded by
Betula pubescens, Pinus silvestris and Picea abies. Sphagnum was rather scattered.
IDF-Report 13 (2008): 17-28
Figure 6: Bog around the river Zholobnytsya: likely breeding site of Nehalennia speciosa.
N. speciosa is a rare and declining species in Europe and in need of strong protection (Bernard & Wildermuth 2005). Old records were known for Ukraine from
the beginning of the 20th century, mainly in the north and western parts and
one record from the south (Gorb et al. 2000). Since 1950 only individual specimens were found in northern Ukraine (Volynska and Chernihiv oblast’) and some
data need confirmation (Bernard & Wildermuth 2005).
The habitat looked similar to those described as breeding sites of N. speciosa in
the literature (Bernard & Wildermuth 2005). In addition, we found more than 20
individuals during one day of observation. This suggests this nature reserve is a
breeding site of N. speciosa. Therefore, the reserve is very important for
Ukrainian odonatology because the ecology of that species can be studied here.
It also provides protection and allows the possible introduction of this species
to appropriate habitats.
Aeshna isosceles (Müller, 1767)
Previous records: rare at bogs, rivers, lakes in July-August (Nadvorny 1996).

Our data: pond around r. Bolotnytsya, 13.06.2007, 1 male, 1 female. The species
is included in the Red Data Book of Ukraine (1994), category III “Rare”.
Cordulia aenea (Linnaeus, 1758)
Previous records: common everywhere in May-August (Nadvorny 1996).
Our data: glade, edges of forest, road, 21.05.2007, 1 male, 1 female; drainage
ditches near the road, 12.06.2007, exuviae, 1 male. Surroundings of reserve,

Somatochlora metallica (Vander Linden, 1825)
Our data: r. Zholobnytsya, 14.08.2006, 1 male; meadow near the village Selezivka
(directorate of reserve) 12.06.2007, 2 males, 1 female; bog on r. Zholobnytsya,
13.06.2007, common species, 1 male, 1 female.
Somatochlora flavomaculata (Vander Linden, 1825)
Our data: meadow near the village Selezivka 12.06.2007, common species, 6
males, 1 female; road in forest, 12.06.2007, 2 females; bog on r. Zholobnytsya,
13.06.2007, common species, 2 males, 1 female.
Somatochlora arctica (Zetterstedt, 1840)
Our data: meadow near the village Selezivka 12-13.06.2007, 2 females.
This is the second record of this species in the Ukraine. The first one was from
the surroundings of Novohrad-Volynsky in 1909: 22.05 – 1 female, 27.05. – 1
female, 02.06. – 1 female (Solodovnikov 1927). This area is situated 100 km to the
SW from the present one.
S. arctica breeds in Sphagnum bogs at localities of the same latitude in Eastern
Poland (e.g. Bernard et al. 2002; Buczynski et al. 2004) and in the Pripyat National Park in Belarus (Dijkstra & Koese 2001). Similar habitats and thus potential
sites for larval development may, therefore, be found within the boundaries of
the Poliskyi reserve.

This is the northernmost record for Ukraine. Previously it was found in western
(Ivano-Frankivsk, Lviv and Zakarpats’ka oblast’), eastern (Donetsk and Lugansk
oblast’) and southern (Odessa and Mykolaiv oblast’) regions and was abundant in
Crimea (Gorb et al. 2000; Sheshurak 2001; Martynov & Martynov 2004; Dyatlova
2006; Matushkina 2006; Khrokalo & Prokopov 2005).

Our data: road in forest, drainage ditches and puddles near the road, glades 1213.06.2006, abundant, 12 males, 10 females.
This species is rare species in Ukraine. It was found at the beginning of the 20th
century in the Kyiv region and in the Carpathian Mountains at an altitude of
more than 1500 m a.s.l. (Gorb et al. 2000). Recent records are from the northeastern Ukraine in Chernihiv (Sheshurak & Khrokalo 2004). and the Sumy oblast’
(Khrokalo 2004).

Leucorrhinia rubicunda (Linnaeus, 1758)
Our data: r. Zholobnytsya, 14.05.2007, 2 males, 1 female; drainage ditches and
puddles near road in forest, 12.06.2006, 2 females.
This is a rare species in Ukraine. Old records were known from western and
northern Ukraine (Gorb et al. 2000). Records in the last decade were from north,
northeast and central Ukraine: the northern part of Sumy oblast’ (Khrokalo
2004), Chernigiv oblast’ (Sheshurak & Khrokalo 2004), Kyiv and Cherkassy oblast’
(Matushkina 2006).
Leucorrhinia pectoralis (Charpentier, 1825)
Our data: road in forest, 12.06.2006, 1 male.
The species is declining in Europe (IUCN, 1998). In Ukraine it is registered on
most of its territory, except the south and the Crimea peninsula, often common
in swamps.
Leucorrhinia albifrons (Burmeister, 1839)
Our data: pond around r. Bolotnytsya, 13.06.2007, 1 male.
The species is declining in Europe (IUCN, 1998). It is rare in Ukraine occurring in
northern Ukraine: Kyiv and Volyn’ region (Gorb et al. 2000, Khrokalo, unpublished
data); and Crimea (Matushkina 2006).
Conclusion
The Poliskyi Nature reserve is important for the protection of dragonflies
because out of the 18 species newly recorded here, 2 are included in the
Ukrainian Red Data Book and 3 in the European Red Data Book. However, common and sometimes abundant species were also found, especially in the
swampy drainage ditches along forest roads (Libellula quadrimaculata and
Leucorrhinia dubia), in the rivers (Calopteryx virgo, Calopteryx splendens; (rarer
than the former), Platycnemis pennipes and Coenagrion hastulatum) and
around ponds ( Anax imperator, Erythromma najas, Coenagrion puella,
Coenagrion pulchellum). Undoubtedly, the most interesting place was the bog
of the river Zholobnytsya, inhabited by Nehalennia speciosa, Libellula fulva and
Somatochlora flavomaculata. The area of the Polisskyi reserve includes most
typical forest Odonata fauna and investigation of this place has to be continued.

Die Libellen des Mt Dulit, Borneo, Sarawak, Malaysia – revisited
- Spendenaufruf des International Dragonfly Fund e.V. 1932, als es noch viel zu entdecken galt und die Planeten außerhalb jeder Reichweite lagen, die Fantasie anregten aber noch nicht Billionen Euro verschlangen,
um ihnen näher zu kommen, die Teflon beschichtete Pfanne noch nicht er funden
war, und als Biodiversität noch kein Schlagwort war, führte die Universität Oxford
eine u.a. der Biodiversität gewidmete Expedition durch. Ziel waren die Dulit
Berge im Zentrum von Sarawak auf Borneo (Malaysia), und als die Expeditionsteilnehmer im Januar 1933 die Heimreise antraten, waren fast 20.000 Insekten
gesammelt worden, die nun auf ihre wissenschaftlichen Bestimmung warteten.
Wer Interesse am Reisebereicht mit eindrucksvollen SW-Fotos der Landschaft
und der Menschen hat, dem schicke ich gerne ein pdf des Berichtes.

Die odonatologischen Sammelergebnisse waren so faszinierend, dass sich
Douglas E. Kimmins vom British Museum of Natural History schon bald an die
Arbeit machte, die Libellen klassifizierte und die Ergebnisse bereits 1936 publiziert waren.
Und wenn ich mich nicht verzählt habe, waren acht Arten neu für die Wissenschaft: Drepanosticta dulitensis, Drepanosticta forficula, Drepanosticta dentifera, Rhinocypha cognata, Orthetrum borneense, Coeliccia cyaneothorax, Rhinoneura caerulea und Bornargiolestes nigra.

Nun wissen wir alle, dass das mit der Biodiversität heute nicht mehr so wie vor 75
Jahren ist. Die Sägen der Menschen, v.a. derjenigen, die ihren Lebensunterhalt mit Holzverkauf fristen müssen, sind schär fer geworden. Und Motorsägen
arbeiten auch schneller als die Sägen, wie sie zu Kimmins’ Zeiten bekannt waren.
Auch der Mt Dulit scheint nicht unbetroffen zu sein, und inzwischen holt man die
Stämme auch aus Regionen mit Hubschraubern raus, wo sie früher für die
Ewigkeit sicher schienen.
Rory Dow, der in den vergangen Jahren viele selbst finanzierte Reisen nach
Borneo unternommen hat – jüngste Ergebnisse wurden u.a. im International
Journal of Odonatology publiziert, und viele Publikationen sind in Arbeit – hat nun
beim IDF angefragt, ob dieser willens wäre, eine Expedition zum Mt Dulit zu finanzieren, um dort zu sammeln, zu dokumentieren und zu photographieren, mit all
dies einen kleinen Beitrag dazu leisten kann, die Region vielleicht doch noch unter
Schutz zu stellen, d.h. die Pläne zur Ausweisung eines Nationalparkes nochmals
hervor zu holen, die Aktivitäten der Holzkonzerne zu stören (stoppen wäre ja
wohl zu viel verlangt), und zumindest die Libellen des Mt Dulit zu dokumentieren.
Mehr als 75 Jahre nach der Oxford-Expedition würden sich alte Freunde gerne
wiedertref fen. 2006 machten Rory Dow und Graham Reels – bekannter
Odonatologe aus Hongkong – den Versuch, den Mt Dulit zu besteigen. Doch dies
misslang, weil die einheimischen Führer keinen Weg mehr nach oben fanden. Am
Fuße des Gebirges waren die Wälder bereits abgeholzt und mit ihnen die alten
Landmarken, die den Weg nach oben wiesen. Nun haben die Leute vor Ort aber
IDF-Report 13 (2008)
doch wieder einen Weg zu den Gipfeln gefunden bzw. einen “Trail” geschlagen,
und so warten denn die Libellen auf Besuch.

Der scheitert aber, wen wundert es, wenn der IDF angeschrieben wird, am Geld.
Nun frage ich die Mitglieder des IDF und sonstigen Freunde der Libellen an, ob sie
Rory Dow den Weg nach oben frei schlagen helfen. Spektakuläre Libellen sollten
der Lohn der Mühen sein und das gute Gefühl, vielleicht doch etwas zur
Sicherung der Biodiversität in Borneo beigetragen zu haben. Wenn nicht, so bleiben wenigstens die Sammlungsexemplare und Photos, die an die gute alte Zeit
2008 erinnern werden.
