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.

Seeds of invasive plants

Introduction

This key is an identification tool for seeds of invasive plants. The choice of species was based on an extensive survey of seeds and seed mixtures in trade, where the seeds of these invasive species were found as contamination.

A total of 143 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. This key is also available in French and Dutch.

EPPO-Q-bank

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.

Key to willow species and hybrids present in New Zealand

This key is illustrated with more than 2000 images of willow species and hybrids that are either wild or in cultivation in New Zealand, and the features that are used to identify them. Most illustrations are of willow clones grown in the national willow collection in Palmerston North maintained by Plant and Food NZ.

The key is designed for those with some experience in plant identification, and some features will need at least a strong hand lens (10x or better) to see features such as stamen filament hairs. It will be of use to bee-keepers, farmers with an interest in growing willows as bee food, and conservation estate managers who need to identify willows in the wild.

Writing of this key was funded by the Sustainable Farming Fund, Trees for Bees NZ, the Willow and Poplar Trust, Plant and Food NZ, and Manaaki Whenua - Landcare Research.

Seedlings of invasive plants

Introduction

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.

A Key to the genera of Australian Jumping Spiders (Araneae: Salticidae)

Identification key: https://apps.lucidcentral.org/salticidae/

The key is intended to meet the needs of naturalists, biologists and taxonomists who wish to identify Australian jumping spiders. The character set has high redundancy (99 characters, 293 character states) allowing users to begin with whatever observable characters are available to them when using photographs, a high-powered hand lens or a microscope.

An information sheet attached to each genus provides a list of known species and information on evolutionary relationships, distribution, habits, a simplified diagnosis, and some key references. A series of diagrams and photographs (of living specimens and of aspects of the morphology, including palps and epigynes) is provided for each genus.

Further information and instructions for using the key can be found in the document attached to ‘Salticidae’ in the top right hand quadrant of the key.

Please send comments, or suggestions for improving the key, and requests for assistance, to [email protected].

The key can be cited as Richardson, B.J., Whyte, R. and Żabka, M. (2019). A key to the genera of Australian jumping spiders (Aranaea: Salticidae). https://apps.lucidcentral.org/salticidae/

Key to the world species of Ips (Coleoptera: Curculionidae: Scolytinae)

About the key

A matrix key designed to allow maximum diagnostic inference from male or female specimens of Ips DeGeer, 1775, including damaged specimens.

Morphologically similar genera of Ipini, Orthotomicus and Pseudips, are included at genus level to help distinguish Ips from these other genera.

Numbers in parentheses in natural language descriptions indicate outlier values observed in only a few specimens.

Key accompanies an article in the Canadian Journal of Arthropod Identification (Douglas et al. in press). This article includes a dichotomous key, and illustrated diagnostic fact sheets for all Ips species and subspecies.

Crop rotations and their resistance to plant-parasitic nematodes

Plant-parasitic nematodes are a major constraint to banana production. An important strategy for management is the use of non-host rotation crops that limit nematode feeding and reproduction.

This selection tool provides recommendations for Queensland horticultural industries on the most suitable rotation crop to manage a specific plant-parasitic nematode. Users enter as much or as little agronomic information as desired and the software will generate a list of responses conforming to that information.

The user is then able to browse the key and instantly open crop fact sheets with further details.

Tardigrades of the Great Smoky Mountains National Park

This is a key and field guide to the Phylum Tardigrada in the Great Smoky Mountains National Park.  It has been developed as part of the All Taxa Biodiversity Inventory (ATBI) (www.dlia.org). The key is designed to cover ONLY species in the park, though it includes approximately 70% of the known eastern U.S. limno-terrestrial species (H. Meyer pers. com.).

Using it for specimens from other sites could give erroneous results.  Characters for taxa above the species level are based on a key to limno-terrestrial tardigrades (including Heterotardigrada and Eutardigrada) by Nelson & McInnes (2002) and a key to Eutardigrada by Pilato & Binda (2010).

For a current checklist of all known tardigrade species, and the authorities for each, go to the University of Modena Tardigrade Webpage.

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.
