Elytroleptus ignitus
(LeConte, 1884)
Elytroleptus ignitus is a longhorned beetle in the Cerambycidae, described by John Lawrence LeConte in 1884. The species was revised taxonomically in 2013, with E. luteicollis synonymized under this name. It is one of three Elytroleptus species documented as on lycid beetles (family Lycidae), which it also mimics in appearance. The occurs in the southwestern United States, Mexico, and Central America.

Identification
Distinguished from other Elytroleptus by specific morphological features detailed in the taxonomic revision; exhibits intraspecific polychromatic variation. As a lycid mimic, share the orange and black aposematic coloration typical of net-winged beetles (Lycidae), making field identification challenging without close examination.
Distribution
Occurs in the southwestern United States, Mexico, and Central America (Guatemala, Honduras, Nicaragua, Rica). Specific locality records for E. ignitus are embedded within the broader -level distribution.
Diet
; feeds on lycid beetles ( Lycidae). One of three Elytroleptus documented as predaceous on its own lycid model.
Host Associations

Behavior
Lycid mimicry; exhibit Batesian or Müllerian mimicry of the aposematic orange-and-black coloration of net-winged beetles (Lycidae). Unlike most cerambycids, actively preys upon its lycid models rather than being herbivorous or .

Taxonomic History
E. luteicollis Skiles & Chemsak, 1982 was synonymized with E. ignitus (LeConte, 1884) in the 2013 revision by Grzymala & Miller. A lectotype was designated for E. scabricollis Bates, 1892 as part of the broader revision.
Predatory Behavior
E. ignitus is one of only three Elytroleptus (along with E. apicalis and E. limpianus) documented as on lycid beetles. This represents an unusual trophic strategy within Cerambycidae, where most species are wood-boring or herbivorous.
