Additional records of the invasive Nearctic true bug Leptoglossus occidentalis Heidemann, 1910 (Heteroptera: Coreidae: Coreinae: Anisoscelini) from Croatia are given from the islands of Rab, Bra~, and Hvar. A new host plant, Pinus halepensis, is reported.

The checklist of the Adriatic decapod fauna is re-examined and supplemented. Several new species for the area are included in the list, new immigrants are noted and some species excluded. The species names are updated and their status and prospects commented on.

Lonjsko Polje is one of the largest and the best preserved flood plains in Europe. Periodical flooding of this area occurs mostly during spring and autumn, and water stays on the ground for more than 100 days. These hydrological conditions provide high habitat diversity with specific ecological factors and represent interesting research objects. Field research for this paper was performed from April to November 2004 on two locations; one flooded and one non-flooded meadow. At both the sites, spider fauna and difference in species composition were determined.

This work presents habitats of 22 neophytes within the Cetina River area. The neophytes – Acer negundo L., Amaranthus albus L., A. blitoides S. Watson, Ambrosia artemisiifolia L., Artemisia verlotiorum Lamotte, Conyza bonariensis (L.) Cronq., C. canadensis (L.) Cronq., Eleusine indica (L.) Gaertner, Euphorbia maculata L., E. prostrata Aiton, Galinsoga parviflora Cav., Paspalum paspalodes (Michx.) Scribn., Tagetes minuta L., Xanthium spinosum L., X. strumarium L. subsp. italicum (Moretti) D. Löve are mentioned for the first time for the researched area. Data are given for new findings of neophytes previously recorded in the area investigated – Amorpha fruticosa L., Aster squamatum (Sprengel) Hieron., Bidens subalternans DC., Conyza sumatrensis (Retz.) E. Walker, Datura inoxia Mill., Erigeron annus (L.) Pers., Phytolacca americana L.

In this paper a preliminary check-list of invasive alien plant species (IAS) in Croatia is presented. It has been created on the basis of the literature and of field observations. The list consists of 64 taxa, with family, life-form and geographic origin assigned to each IAS. Analyses according to family affiliation, life-form and origin were made. Out of 27 families the majority (24 families) belong to the dicotyledons. The most numerous family is Asteraceae, and genera with the highest number of IAS are Conyza, Erigeron and Impatiens. Life-form analysis showed the predominance of therophytes but also presence of hemicryptophytes, phanaerophytes and geophytes. In the origin analysis, IAS from the Americas predominated, followed by those from Asia and Africa.
