The red eft (juvenile) stage is a bright orangish-red, with darker red spots outlined in black. An eastern newt can have as many as 21 of these spots. The pattern of these spots differs among the subspecies. An eastern newt's time to get from larva to eft is about three months.
Plants are slow growing and take a few years to grow large enough to flower. The western subspecies is ssp. arguta, and the northern subspecies is ssp. rubra. [5] These subspecies are not well differentiated, and in many locations, each grades in to the other over much of their ranges. [6]
The terrestrial juvenile phase is called an eft. Unlike other members of the family Salamandridae, newts are semiaquatic, alternating between aquatic and terrestrial habitats. Not all aquatic salamanders are considered newts, however. More than 100 known species of newts are found in North America, Europe, North Africa and Asia.

The red-bellied newt is also similar but has dark irises vs. yellow in the California newt, more red coloration underneath, and a dark band across the vent that is lacking in the California newt. [7] [citation needed] Newts are amphibians. They are related to salamanders (in a subfamily called Pleurodelinae). They live in North America, Europe ...
The red-bellied newt is brown on the upper body with a red underbelly, has grainy skin, and grows to between 5.5 and 7.5 in (14 and 19 cm). It can be distinguished from other coastal newts, not only by its red belly, but also by the lack of yellow in its eyes. Breeding males develop smooth skin and a flattened tail. [4]
The species was first described scientifically by American mycologist Howard James Banker in 1913. [2] Italian Pier Andrea Saccardo placed the species in the genus Hydnum in 1925, [3] while Walter Henry Snell and Esther Amelia Dick placed it in Calodon in 1956; [4] Hydnum peckii (Banker) Sacc. and Calodon peckii Snell & E.A. Dick are synonyms of Hydnellum peckii.
The mite parasitizes a variety of insect hosts and is able to bite humans, causing red, itchy, and painful wheals (welts). The mites are barely visible, measuring about 0.2–0.8 millimeters; their great reproductive potential, small size, and high capacity for dispersal by wind make them difficult to control or avoid.
