Global diversity of dragonflies (Odonata) in freshwater
TLDR
Diversity is discussed, the biogeography of dragonflies in the different biogeographical regions is summarised and the total number of species and genera per family perBiogeographical region is given.
Moth assemblages as indicators of environmental quality in remnants of upland Australian rain forest
TLDR
The results show how moth assemblages are powerful indicators of forest disturbance, and should prompt parallel studies elsewhere in the world.
The classification and diversity of dragonflies and damselflies (Odonata)
TLDR
It is argued for conserving the family-group names Chlorocyphidae, Euphaeidae and Dicteriadidae, as well as retaining Epiophlebiidae in the suborder Anisozygoptera, while the proposal to separate Chlorogomph Families, Cordulegastridae and Neopetaliidae from Libelluloidea in their own superfamily CordUlegastroidea is adopted.

Butterflies of Australia explains and illustrates much of the known behaviour and ecology of Australian butterflies, and in so doing meets the needs of both the butterfly watcher and general nature lover.
Foraging in the giant forest ant, Camponotus gigas (Smith) (Hymenoptera: Formicidae): evidence for temporal and spatial specialization in foraging activity
TLDR
The foraging behaviour of the giant ant Camponotus gigas, was studied in primary lowland rainforest in Brunei and it is suggested that the canopy is avoided during the day due to high temperatures and low humidity, and the ground is avoided at night due to increased predatation risks.
Remarks on the taxonomy of Megapodagrionidae with emphasis on the larval gills (Odonata)
TLDR
Within the Megapodagrionidae the genera with horizontal gills are the only ones lacking setae on the shaft of the genital ligula, and it is suggested that this group is monophyletic.
