TL;DR: The behavior of ants digging through sand or clay in the direction of trapped nestmates has been described by Belt (1874) and Lafleur (I940) and later, McGurk et al. (1966) identified the responsible compound as 4-methyl-3-heptanone.
Abstract: The behavior of ants digging through sand or clay in the direction of trapped nestmates has been described by Belt (1874) and Lafleur (I940). Wilson (1958) showed that in Pogonomyrmex badius (Latreille) this behavior pattern is released by a volatile substance originating from the mandibular glands. Later, McGurk et al. (1966) identified the responsible compound as 4-methyl-3-heptanone. At the same time, Blum and Warter (1966) isolated 2-heptanone from Conomyrma pyramica (Roger) and described its function as the releaser of alarm and digging behavior. Spangler (1968) reported that not only whole workers, but also amputated parts as well as larvae and pupae of Pogonomyrmex occidentalis (Cresson) attract workers of this species and release digging behavior. Forrest (1963) studied Lasius flavus nearcticus and four species of Acanthomyops and found that workers also dig to free ants of another species but attack them as soon as they are released.

TL;DR: Larvae of the trematode Zoogonus lasius are involved in most double infections of Nassarius obsoleta and the two most common trematodes do not occur together in double infections.
Abstract: Larvae of the trematode Zoogonus lasius are involved in most double infections of Nassarius obsoleta. The two most common trematode parasites of this snail do not occur together in double infections. Double infections were found in 14 of 340 infected snails in a total sample of 5025 snails.
