Zopherus nodulosus, common name Haldeman's Ironclad beetle,[2] is a species of ironclad beetle in the family Zopheridae.[3] It is found in Central America and North America.[4][5][6]

The species name nodulosus refers to the bumps or nodes on the beetle's back.[7][8]

Subspecies

Zopherus nodulosus haldemani pattern variation
Z. n. haldemani

Z. n. haldemani (Horn, 1870),[3][9] also known as the Texas Ironclad Beetle,[8] can grow between 1.5 and 2 centimetres in length. The body is a blotchy black-and-white pattern, and the legs are fully black.[10][11] The subspecies name, haldemani, references the Haldeman brothers (Samuel Haldeman and Horace Haldeman), the former a naturalist and philologist, the latter a soldier and one of the first people to concentrate on insect collection in Texas.[12][13][8][9]

They are thought to feed on lichen and dead plant material.[8][11] Females have been observed laying eggs on American elms, and larvae and pupae have been found in pecan wood,[11][9] which "apparently serves as the developmental site for this species".[11] They are found in East and Central Texas.[14][9]
Z. n. nodulosus

Z. n. nodulosus can grow between 1.4 and 2.8 centimetres in length, and 0.5 to 1.1 cm in width.[15]
