Classification of Poisonous Spiders in Indiana
Species of spiders are classified according to shared physical characteristics. Spider taxonomy is the science of finding, describing, classifying and naming organisms in a hierarchical system. This method of classification helps when a description of 40,000 spiders is required! The organization of living things have seven major categories: Kingdom, Phylum, Class, Order, Family, Genus, Species. The classification of Poisonous Spiders in Indiana are as follows:

Kingdom: Animalia
(Kingdom relates to the highest taxonomic group into which organisms are grouped; one of five biological categories: Monera or Protoctista or Plantae or Fungi or Animalia) :

Phylum: Arthropoda
(Phyla are groups of classes. A series of animals or plants genetically connected with shared characteristics. The second biggest grouping in taxonomy. Arthropoda are jointed-foot invertebrates: arachnids, crustaceans, insects etc

Class: Arachnida

A Class are taxonomic group containing one or more orders. Arachnid  consist of any of the eight-legged creatures, including spiders and scorpions, of the class Arachnida

Order: Araneae
A taxonomic order, within the class Arachnida (spiders)

Subclass:
The Subclass is nother taxonomic category below a class and above an order which helps in the classification process

Family: Brown Recluse:               Sicariidae
               Northern Black Widow:  Theridiidae
Another taxonomic category below an order and above a genus which helps in the classification process.

Genus: Brown Recluse:                Loxosceles
               Northern Black Widow:  Latrodectus

Another taxonomic category below a family and above the level of species which helps in the classification process

Species: Brown Recluse:                L. reclusa
