Identification - Assessment Of Insects Found In Vivariums Under The Orders Of The Phylum Arthropoda.

Phylum Arthropoda

The goal of this article is to help in the identification and assessment of insects found in one's vivarium. This article will only cover Orders of the Phylum Arthropoda.

Identification characteristics are listed under each category. A 'risk' assessment is also located under each Order.

II. Order Decapoda- Crabs, Shrimp, Lobsters, Crayfish

Phylum Arthropoda

Arthropods have jointed and a hard exoskeleton composed of chitin. Their exoskeleton provides protection and support. The rigid nature of the exoskeleton means that arthropods can only grow through periodic molting of the cuticle (ecdysis).

Subphylum Uniramia

Largest major group of arthropods. Uniramians have a single branch in their appendages (uniramious).

A. Class Insecta-Insects

Insects are divided into almost 40 different orders mostly based on the basis of mouthparts, wings, and other morphological features. Although the mouth parts on insects appear to be entirely different they are composed of the same three pairs homologous appendages.

B. Class Chilopoda- Centipedes

Centipedes are usually found in moist habitats such as leaf litter or under logs or rocks. They vary in size from 3-6 centimeters with some tropical forms reaching 18-26 centimeters. Centipedes can have anywhere from 15 to 177 pairs of legs, their is always an odd number of pairs of legs. Centipedes are predatory and use their large fangs to hunt worms and insects. The head has two pairs of Maxillae. The jaws are covered by the first pair of legs (maxillipeds), which look and functions as jaws, they contain poison glands. They live in soil and humus and beneath stones, logs, and bark.

Vivarium Insects

I. Order Scutigeromorpha- House Centipedes
II. Order Lithobiomorpha
III. Order Scolopendromorpha
IX. Order Geophilomorpha

C. Class Diplopoda- Millipedes

Millipedes are important decomposers of rotten wood, eating mostly dead and decaying plant matter however some are carnivores and others eat moist living plants. Many groups of millipedes have well-developed chemical defense glands, which produce repellents and toxins. Millipedes have from 47 to 375 pairs of legs and from 25 to 100 body segments.
