摘要

摘要：蚂蚁是陆地生态系统中极其重要的捕食者，但令人惊讶的是，关于它们在蜜蜂捕食中的作用的报道却很少。在这里，我们描述了蚂蚁Pogonomyrmex subnitidus Emery，1895年在犹他州的一个蜂巢聚集地觅食。在许多例子中，人们观察到了P.subnitidus和另一只蚂蚁Pheidole clydei Gregg（1950）在最近描述的蜜蜂Anthophora pueblo Orr（2016）的巢穴中觅食，该蜜蜂在砂岩中筑巢。还观察到一只亚种工蚁将一只活蜜蜂幼虫带回巢穴，这表明这些蚂蚁偶尔会充当捕食者。与先前关于白天双峰觅食策略的报道相比，亚斑蝶夜间觅食的存在表现出更大的时间觅食可塑性。讨论了这种行为的潜在驱动因素，以及这两种新的蚂蚁伙伴与蜜蜂的关系。

Nocturnal Foraging by Ants at a Sandstone Bee Nest Aggregation (Hymenoptera: Apidae and Formicidae)

ABSTRACT: Ants are immensely important predators in terrestrial ecosystems but surprisingly little is reported on their role in bee predation. Here, we describe the ant Pogonomyrmex subnitidus Emery, 1895 foraging at a bee nest aggregation in Utah. Many instances were observed of P. subnitidus, and another ant, Pheidole clydei Gregg, 1950, scavenging on the nests of the recently-described bee Anthophora pueblo Orr, 2016, which nests in sandstone. One worker ant of P. subnitidus was also observed taking a live bee larva back to its nest, indicating that the ants occasionally act as predators. The existence of nocturnal foraging in P. subntidus demonstrates greater temporal foraging plasticity than prior reports of bimodal foraging strategy during the day. Potential drivers of this behavior and the relation of these two new ant associates to the bees are discussed.
