The visceral leishmaniasis (VL) vector Phlebotomus argentipes Annandale & Brunetti is widely distributed throughout the Indian sub-continent and S.E. Asia. The absence of VL in areas such as Sri Lanka has been attributed to the zoophilic nature of P.argentipes, since they were not recorded biting man. Field studies on P.argentipes were undertaken in the central highlands of Sri Lanka, near Kandy, in May 1988. Male sandflies outnumbered females on cows by 19:1, and were regularly spaced at all densities. This behaviour is considered analagous to swarming in other Nematocera. However, all-night human-biting catches show the biting rate to be similar (mean = 8.4, range 2-25 bites per night over ten consecutive nights) to that in N.E. India where VL is endemic. This anthropophagy was maintained during laboratory colonization.
内脏利什曼病（VL）的传播媒介银足白蛉（Phlebotomus argentipes Annandale & Brunetti）广泛分布于印度次大陆和东南亚地区。在斯里兰卡等地区没有VL病例，这被归因于银足白蛉的嗜动物性，因为没有记录到它们叮咬人类。1988年5月，在斯里兰卡康提附近的中部高地对银足白蛉进行了实地研究。在牛身上，雄性白蛉的数量比雌性多19倍，并且在所有密度下都有规律地分布。这种行为被认为类似于其他长角亚目昆虫的群聚行为。然而，通宵的人饵诱捕显示，叮咬率与VL流行的印度东北部地区相似（平均 = 8.4，连续十个晚上每晚叮咬2 - 25次）。在实验室饲养过程中，这种嗜人性得以保持。
