The pharaoh ant (Monomorium pharaonis) is a small (2 mm) yellow or light brown, almost transparent ant notorious for being a major indoor nuisance pest, especially in hospitals. [1] A cryptogenic species, it has now been introduced to virtually every area of the world, including Europe, the Americas, Australasia and Southeast Asia. It is a ...
Thorax and pedicel of a brownish black, head and basal segment of the abdomen reddish yellow. Best of the abdomen yellow with a tinge of red. Legs and antenna) very pale testaceous. Multifunctional mandibles: The ant's mandible exhibits spatially-dependent morphology and bi-axial kinematics, which collectively allows it to perform various daily ...
The yellow meadow ant (Lasius flavus), also known as the yellow hill ant, is a species of ant occurring in Europe (where it is one of the most common ants), Asia, and North Africa. [1] Populations in North America are now considered a different, related species, Lasius brevicornis. [2] The queen is 7–9 mm long, males 3–4 mm and workers 2 ...
Queens in this species measure at just over 5mm in length and range from a yellow to a light brown color. Workers are yellow and occasionally pale brown in appearance.

The tarsi is lighter but with a more reddish tone. The abdomen is a golden yellow colour. They have similarities to some Myrmecia species as they do not have teeth, which most of its kind contain. [2] [3] [4] Myrmecia piliventris has a genome similar to that of the jack jumper ant.
The stridulatory organ that velvet ants possess produces an audible squeaking when the abdomen is contracted. [15] This mechanism is an auditory cue warning predators that are about to attack to stay away. In one experiment, every time a shrew got within 1 meter of a velvet ant, the velvet ant would begin stridulating. [12]
Being one of the larger ant species, adult individuals have been observed to be as long as 15 mm to 30 mm in body length. The head and thorax are typically coloured red-brown; the rear half of the abdomen is black and the mandibles brown-yellow.
