Seedlings of invasive plants


This key helps to identify seedlings of invasive plants, so plants can be recognized in an early stage of development. The species included are those of invasive terrestrial plants and/or plants which are introduced as weeds in imported potplants.

A total of 92 species is included. All features are illustrated with botanical drawings so that no knowledge of botanical terms is needed, basic knowledge of plant morphology, however, is helpful. The keys link to complete species descriptions on the Q-bank – Plants website. All species are well illustrated by photographs showing distinguishing characteristics or invaded sites. Several species are also treated in the Key to the invasive terrestrial plants and/or the Key to the Weeds in bonsai plants. This key is also available in French and Dutch.


EPPO-Q-bank covers the following organism groups that contain quarantine organisms:

  • Fungi
  • Bacteria
  • Invasive Plants
  • Nematodes
  • Arthropods
  • Phytoplasma’s
  • Viruses and viroids

The databases are managed by EPPO – the European and Mediterranean Plant Protection Organization and curated by internationally known specialists and contain specimen-based information including molecular data. The website offers the possibility to blast, in single- or multi-locus mode, sequences for identification.

Thysanoptera Aotearoa (Thrips of New Zealand)

There have been few studies on the thrips of New Zealand. Most of the information presented in this system is derived from two Fauna of New Zealand volumes (Mound & Walker 1982; 1986). However, much of the data in those two volumes was derived from limited amounts of field work, both in space and time. Particularly missing are biological studies on thrips species that are native to New Zealand, with many of these remaining known from very few specimens.

Only for some Thripidae have there been studies on biology and host-plant range. Teulon & Penman (1990) produced outstanding data on the diversity of plants on which Thrips obscuratus breeds. Martin & Mound (2004) explored the host associations of several species, and Martin (2017) provided good data on the host plants of Panchaetothripinae in New Zealand.

For the many species of fungus-feeding Phlaeothripidae there have been no studies on biology or behaviour, although the sexual dimorphism and male polyphenism many such species exhibit suggests the existence of competitive behaviours.

Thrips of Brazil

The Thysanoptera fauna of Brazil is one of the most diverse in the world. More than 530 species were described based on material collected in Brazilian territory and approximately 700 species are recorded from this country. This number represents more than 10% of the species described in the Thysanoptera. Besides the large number of species, the Brazilian fauna is also diverse in terms of ecology and life histories.

In this identification system, the user can identify the 6 Thysanoptera families that occur in Brazil.

Key to Insect Orders

Predictions about the biology, behaviour and ecology of an insect can often be made once you know to which of the 32 Orders that insect belongs. But how can you find this out?

Insects can be identified in various ways. Comparing a specimen with a book of illustrations of identified insects is one way; using a printed key to Insect Orders is an alternative. This Lucid Mobile Key to Insect Orders combines the advantages of both methods by adding a new dimension of simplicity and power to the process of identification. Designed for a range of users, including secondary school students, beginning undergraduates and anyone with an interest in entomology, this key uses the popular Lucid matrix system together with images of typical species within each Order to help identify to which Order most common adult insects belong. The fact sheets for each Order provide information about identifying features, the structure and biology of insect species within that Order, as well as other relevant information.

The 'Key to Insect Orders' was originally created by staff at the Department of Entomology at the University of Queensland, Brisbane, Australia but has recently been revised (2019) by Professor Steve Marshall at the University of Guelph, Ontario, Canada.

A Key to the Genera of Endeostigmata and Sphaerolichida

This is a key to the genera of primitive acariform mite groups Endeostigmata and Sphaerolichida written and compiled by Dr David Evans Walter of Colorado State University and the University of Alberta with the assistance of Dr Heather Proctor of the University of Alberta.

Endeostigmatans are common in many habitats, but seem to reach their highest abundances in extreme habitats such as deserts, beaches, and polar regions. As far as is known, these mites are fungivores, algivores and predators on small invertebrates such as nematodes, tardigrades, and mites.  None are considered economically important pests.  They are most likely to be intercepted in goods containing soil, especially dry soils including sand, lichens, mosses or other materials associated with dry or otherwise extreme habitats, including anthropogenic accumulations of dust.

Thrips of California 2019

This revised version of Hoddle et al. (2012) has been produced partly to overcome technical problems arising from Java software and partly to incorporate new information and images, together with some additional potentially invasive species.

Information pages are provided to 300 species in 108 genera, with the identification system discriminating 249 species. Of these species, 40 are as yet unrecorded in California but are potential invaders, whether interstate or from overseas.

They have been included for the convenience of quarantine services in USA. In contrast, the Thysanoptera fauna of the American continent north of Mexico has been estimated to comprise 700 described thrips species (Arnett, 1985), with 147 species recorded from Canada (Foottit & Maw, 2019). This identification system is based essentially on adult females, these being the most commonly collected individuals.

For larval thrips, the only modern identification system is to part of the Thripidae fauna of Europe (Vierbergen et al., 2010).

WATTLE Acacias of Australia ver. 3

This WATTLE ver. 3 key (which is also available as an App) enables users to identify wattle plants that occur anywhere in Australia or elsewhere in the world where they are grown. It includes 1,057 formally described species of Acacia, plus several hybrids and informal taxa of this genus. It also includes two species of Acaciella, four species of Senegalia and nine species of Vachellia that occur in Australia and which were previously included in Acacia.

WATTLE ver. 3 builds upon two previous versions of WATTLE, namely, the original version that was published in 2001 on CD and version 2 that was published in 2014 on the Lucidcentral website. Compared with earlier versions, which are no longer available, WATTLE ver. 3 contains more species, updated coding and new or updated descriptions for each taxon, together with photographs and improved distribution maps.

At the heart of WATTLE is a powerful Lucid identification key which helps people of all ages to quickly and accurately identify species. The key is a truly random access tool, one that allows users to enter, in any order, the characteristics of a specimen that they wish to identify. The key then lists those species possessing the characteristics nominated, rejecting those that do not match the criteria entered. By progressively providing additional characteristics about the unknown specimen, users can narrow the search, eventually ending up with just one or a few species.

The key provides context-relevant information (text and images) that assist users to correctly interpret the characteristics of the plant they are attempting to identify. For those who want information about the species that has been identified, WATTLE ver. 3 provides fact sheets containing illustrations, detailed descriptions, photographs and maps that can be accessed directly. Hyperlinks provide simple navigation between fact sheets of related or similar species.

WATTLE ver. 3 is jointly published by the Australian Biological Resources Study (ABRS), Canberra, The Western Australian Department of Biodiversity, Conservation and Attractions (formerly CALM) and Identic Pty Ltd, Queensland. WATTLE complements the Flora of Australia (
