Diet

feed on necrotic tissue of wounds; laboratory rearing has used fresh beef as substrate.

Host Associations

humans - facultative causing traumatic
livestock - facultative causing traumatic
horses (Equus caballus) - facultative causing traumatic Wohlfahrtia magnifica specifically recorded from vulvar wounds in Hungary

Life Cycle

: females directly onto substrate. Three larval occur, followed by prepupal stage and in soil. In Wohlfahrtia nuba, first instar larvae measure approximately 4.95 mm length with cephalopharyngeal skeleton 1.63 mm; bear 8 in first instar, 10 in second, 11 in third; spiracles have two incomplete with slit count increasing from 1 to 2 to 3 across instars. First instar larvae are and penetrate wound tissue; later instars remain non-invasive within the wound.

Behavior

are attracted to decomposing corpses and serve as early colonizers of decomposition. First actively penetrate wound tissue; later instars remain localized within wounds. Wohlfahrtia magnifica adults in Hungary are active May through September. females are attracted to wound sites, possibly by volatile chemical cues associated with tissue inflammation or physiological states.

Ecological Role

Facultative causing traumatic in mammals; contributes to decomposition as early colonizer of carrion. Forensic for postmortem interval .

Human Relevance

Causes traumatic in humans and domestic animals, particularly livestock. Wohlfahrtia magnifica in horses can cause severe tissue destruction and secondary , requiring veterinary intervention. Forensic importance for criminal investigations and death scene analysis.
