List of Idaho state symbols

Columns: Type | Symbol | Description | Adopted
Amphibian | Idaho giant salamander | The Idaho giant salamander ( Dicamptodon aterrimus ) is the largest salamander found in the state of Idaho , where it lives almost exclusively . Over their lifetime , these salamanders will metamorphose from a larva to a terrestrial adult , or will mature into an adult but retain the larval form , such as keeping gills , growing to lengths of 33 cm ( ~13 in ) . Idaho giant salamanders are generally found in moist coniferous forests and can change colors . The transformed adults are secretive and seldom found in the open , but can be found in moist areas | 2015 | Bird | Mountain bluebird ( Sialia currucoides ) | Adopted as the state bird by the Idaho Legislature in 1931 , the mountain bluebird is one of two bluebird species found in the state . Known for their bright blue plumage , these migratory birds often arrive in Idaho in late February or early March , nest , then migrate south in September or early October | 1931 | Dance | Square dance | 1989 | Fish | Cutthroat trout ( Oncorhynchus clarkii ) | Native to Idaho , the cutthroat trout 's name comes from the distinctive red to orange slash on the underside of its jaw . During an attempt to designate a state fish in 1988 , critics of the cutthroat pointed out that the species was not found throughout the entire state . When the Legislature adopted the species in 1990 , bill sponsor Mary Lou Reed called the cutthroat a good symbol of the state 's quality of life | 1990 | Flag | Flag of Idaho | 1907 | Flower | Syringa ( Philadelphus lewisii ) | Documented and collected by Meriwether Lewis in 1806 , the syringa was designated the Idaho State Flower in 1931 | 1931 | Fossil | Hagerman horse ( Equus simplicidens ) | The Hagerman horse ( Equus simplicidens originally described as Plesippus shoshonensis ) was declared the official state fossil of Idaho by the 1988 Legislature . A 3.5 million year old fossil bed near Hagerman , discovered in the 1920s , has yielded more than 30 complete horse skeletons and is said to be the best known Pleistocene-epoch fossil site in the world . Hagerman Fossil Beds National Monument , specifically the Hagerman Horse Quarry , contains the largest concentration of these fossils | 1988 | Fruit | Huckleberry | Several huckleberry species are native to Idaho ( all belonging to genus Vaccinium ) , the most popular of which are black or thin-leaved huckleberry ( Vaccinium membranaceum ) . The berries are difficult to grow commercially , as they can take up to 15 years to reach maturity , grow at specific elevations , and attempts to transplant often end in failure . However , attempts are underway to domesticate the berry . Students from Southside Elementary School proposed the huckleberry as the state fruit in 2000 | 2000 | Gem | Star garnet | Star garnet , found only in Idaho and India , was designated as the state gem in 1967 | 1967
