Eukarya- Omus californicus is a multicellular organism in which the cells contain a nucleus and membrane bound organelles.

Animalia- The beetle is an ingestive heterotroph with specialized cell functions and resproduces sexually.

Arthopoda- More commonly known as arthropods, these animals have a hard chitin composed exoskeleton that provides structural support for the organism. these organisms have bilateral symmetry, jointed apendages, a segmented body, are protosomes, and triploblastic, and molt.

Hexapoda- Literally meaning "six footed," the subphylum comatins four groups including insects, scullenbola, proturn, and diplura (Bartlett 2004).
Phylogentic Tree I
nsecta- This taxonomic class includes the insects, all of which have three body parts: the head, the thorax, and the abdomen. Insects also have one pair of antennae and commonly have at least one pair of wings.

Coleoptera- Better known as beetles, the organisms within this order have a segmented abdomen, moveable mouthparts adapted for chewing, and have a hardened head plate during the larval stage for protection (Bartlett 2004).

Adephaga- The ground and water beetles are the second largest suborder from the order coleoptera which generally are predators that have evolved chemical secretion defensives formed from the pygidial defense glands to ward off other predators (Person et al 1988).

Carabidae- This family includes all ground beetles which have six segmented legs with two claws and two associated types of mandibles (Ball et al. 2011). 

Cicindelinae- California Night-stalking Tiger Beetles are classified under all tiger beetles which have sickle shaped mandibles and live in open habitats. At one time, the subfamily cicindelinae was combined with the carabidea family to form one immense group (Kinsley and Juliano 1998).
 
         Figure 2. This phylogentic tree reveals that insects are            
         classified under arthropods, and are most closely related
         to crustaceans.                                                               
                                                                                                         
Amblycheilini- There has been found to be greater manidbles robustness, and enlargement of the terebral tooth (Ball et al. 2011).

Omus- Organisms found in this genus some of the most primitive tiger beetles (Pearson et al. 1988). and are dark brown or black, flightless, primarily nocturnal, night stalking tiger beetles with fused elytra Bartlett 2004). This genus is one of most poorly known genus of North American tiger beetles (Kinsley and Haines 2010). There are five to fifteen species with only five bing offically cited and published within this genus. Because of the intraspecifc and interspecific variation amoung the genus and individual populations, it is difficult to classify these organisms within the correct taxonomic level (Kinsley and Haines 2010).

Omus californicus- this organism is a night stalking tiger beetle found primarily in California and the Southwest areas of Oregon, therefore, termed the California Night-stalking Tiger Beetle. There have been four named subspecies for this species (Bartlett 2004).
