They eat grease whenever they find it, which is why they are sometimes called grease ants. They also eat meat, cheese and other dairy products, and seeds. They also eat larvae and pupae of other ant species and other insects such as codling moths. Thief ants do not appear to be attracted to sweets, unlike most other ants.
Colobopsis explodens is a species of ant which is found in Southeast Asia. Like some other species in its genus, it is noted for a rare combat mechanism of workers exploding in self-defense, smothering the enemy with toxic and often deadly secretion. [1]
Often, the ants will not only receive housing from the plant; they will eat extrafloral nectar and food bodies that the plant provides. In return, the plant receives security from herbivores that may eat the plant, because the ants hunt on the plant and eat many of the plant’s predators. This symbiosis benefits both the plant and ants. [1]
In the case of fire ants, the venom consists mainly of alkaloid (>95%) and protein (<1%) components. [2] Stinging ants cause a cutaneous condition that is different from that caused by biting venomous ants. Particularly painful are stings from fire ants, although the bullet ant's sting is considered by some to be the most painful insect sting.
Birds that follow ants eat many prey insects and thus decrease the foraging success of ants. [198] Birds indulge in a peculiar behaviour called anting that, as yet, is not fully understood. Here birds rest on ant nests, or pick and drop ants onto their wings and feathers; this may be a means to remove ectoparasites from the birds.
The jack jumper ant (Myrmecia pilosula), also known as the jack jumper, jumping jack, hopper ant, or jumper ant, is a species of venomous ant native to Australia.Most frequently found in Tasmania and southeast mainland Australia, it is a member of the genus Myrmecia, subfamily Myrmeciinae, and was formally described and named by British entomologist Frederick Smith in 1858.
Tapinoma sessile is a species of small ant that goes by the common names odorous house ant, sugar ant, stink ant, and coconut ant. [1] Their colonies are polydomous (consisting of multiple nests) and polygynous (containing multiple reproducing queens ).
The most notable component found in the venom of the Maricopa harvester ant is an alkaloid poison—this releases an "alarm" pheromone that chemically alerts other ants in the vicinity. This is an example of chemical signaling , which explains why ants all appear to sting at once.
