An investigation of the landing and engorging sites of midges on a bait horse was made in Ireland as part of a project examining the aetiology of sweet itch. Ten species were recovered, seven of which engorged. Culicoides obsoletus and C dewulfi were the most commonly represented, accounting for 89.9 per cent of midges landing and 90.5 per cent of midges engorging. Only 4.69 per cent of midges attracted to the bait were C pulicaris. Overall, the preferential landing sites for midges were along the mane and lower leg regions. Few culicoides were attracted to the head, front and underside of the animal. Two species, C punctatus and C nubeculosus, fed exclusively at the predilection sites of sweet itch but in very small numbers. C pulicaris fed predominantly at these sites also and represented 5.08 per cent of the engorging catch. Of 10,178 midges attracted to the bait, 4097 (40.3 per cent) engorged; the majority of the species taking full blood meals fed on the mane and lower legs. Midges biting in other areas tended to have smaller meals. Areas along the dorsal midline of the body are predilection sites for sweet itch lesions and are preferential engorging sites also. However, considerable engorgement occurred on the lower legs where sweet itch lesions do not occur.
作为一项研究甜痒病因项目的一部分，在爱尔兰对诱饵马身上蠓的着陆和吸血部位进行了调查。共发现了10个物种，其中7种吸血。废弃库蠓和德氏库蠓最为常见，分别占着陆蠓的89.9%和吸血蠓的90.5%。被诱饵吸引的蠓中只有4.69%是刺螫库蠓。总体而言，蠓的优先着陆部位是沿鬃毛和小腿区域。很少有库蠓被动物的头部、前部和腹部吸引。有两个物种，即斑点库蠓和云雾库蠓，只在甜痒的好发部位吸血，但数量非常少。刺螫库蠓也主要在这些部位吸血，占吸血捕获量的5.08%。在被诱饵吸引的10178只蠓中，4097只（40.3%）吸血；大多数吸食全血的物种在鬃毛和小腿上吸血。在其他部位叮咬的蠓吸血量往往较小。身体背中线沿线区域是甜痒病变的好发部位，也是优先吸血部位。然而，在小腿上也发生了大量吸血，而小腿上并没有甜痒病变。
