Belminus ferroae (Hemiptera: Reduviidae) was collected from houses in the localities of San Alberto and Santa Catalina in the municipality of Toledo, Department of Norte de Santander, Colombia. Precipitin tests revealed that the main hosts of B. ferroae are insects belonging to the order Blattodea, whose haemolymph serves as food (89.43%). A low rate of haematophagy was indicated on rodents, dogs and humans (7.32%) and no natural infection with Trypanosoma cruzi was found by either microscopic examination or polymerase chain reaction. The finding of B. ferroae inside houses, feeding primarily on Blattodea with only a minor tendency to feed on vertebrate blood, is indicative of both the evolutionary path from predator to blood-sucker taken by Triatominae and their tendency to adapt from silvatic to domestic habitats.
费氏猎蝽（半翅目：猎蝽科）采自哥伦比亚北桑坦德省托莱多市圣阿尔韦托和圣卡塔利娜地区的房屋。沉淀素试验表明，费氏猎蝽的主要宿主是蜚蠊目昆虫，其血淋巴是食物来源（89.43%）。对啮齿动物、狗和人类的吸血率较低（7.32%），通过显微镜检查或聚合酶链反应均未发现克氏锥虫的自然感染。在房屋内发现费氏猎蝽，主要以蜚蠊为食，仅具有轻微的吸食脊椎动物血液的倾向，这既表明了锥蝽亚科从捕食者到吸血者的进化路径，也表明了它们从野生栖息地适应到家栖环境的趋势。
