Because our recordings terminated before the adults left the burrows at the end of the night, we may have missed some late feedings.
Some plant-feeding insects that feed on only one or a few closely related plant species have taste receptor cells specialized to perceive chemicals specific to the host.
In early free-swimming larvae and the adults of some filter-feeding or deposit-feeding amphipods, isopods, and hemicarideans and in large carnivorous palinuran decapods, food may be gathered (occasionally killed) by means of the antennae and other head appendages.
Some filter-feeding ciliates, such as the tintinnids, however, are known to be selective and appear to be able to capture or reject items that arrive at the feeding membranelles in the feeding current.
For example, plants in the cabbage family (crucifers) are characterized by a class of compounds called glucosinolates, and some crucifer-feeding insects have cells that respond only to glucosinolates, often exhibiting greatest sensitivity to the specific glucosinolates that occur in their normal hosts.
But as Cotton points out, that may not always work in their favor: Because insects' emergence is triggered by the climate in their own environment, some insect-feeding birds may arrive from Africa either too early, before their favorite bugs have emerged, or too late, after resident birds have already gobbled them up.
Some nectar-feeding birds are important pollinators, and many frugivores play a key role in seed dispersal.
They are a component of the diet of the red squirrel, and serve as breeding sites for some fungus-feeding flies in the Drosophilidae and Mycetophilidae families.
And it is easy enough to miss a court summons, which may have been delivered to the wrong address or, in the case of some bottom-feeding bill collectors, simply tossed in the garbage -- a practice so common that the industry even has a term for it: "sewer service".
The same vocal advertisement is used by some frog-feeding mosquitoes and other blood-sucking flies, which eavesdrop on calling males to locate their hosts [16], [17], [18].
