Ants belonging to the genus Solenopsis are known as "fire ants" because of the pain caused by their stings, which inject venoms. The venoms of fire ants are characterized by a variety of alkaloids known as solenopsins (2-methyl-6-alkylpiperidines) that exhibit necrotic , hemolytic , antibiotic , and toxic properties. [ 12 ]
Fire ant queens, the reproductive females in their colony, also are generally the largest. Their primary function is reproduction. Typically, a fire ant queen will seek to establish a new colony following a nuptial flight, wherein it will use its special venom to paralyze offending competitors, [17] in the absence of workers for defense. Fire ...
A queen ant (formally known as a gyne) is an adult, reproducing female ant in an ant colony; she is usually the mother of all the other ants in that colony. Some female ants, such as the Cataglyphis , do not need to mate to produce offspring, reproducing through asexual parthenogenesis or cloning , and all of those offspring will be female. [ 1 ]
The gyne (/ ˈ ɡ aɪ n /, from Greek γυνή, "woman") is the primary reproductive female caste of social insects (especially ants, wasps, and bees of order Hymenoptera, as well as termites). Gynes are those destined to become queens , whereas female workers are typically barren and cannot become queens.
Scientists found that 10 or more fire ants can stick together to build a life-saving raft in floods.. Fewer than 10 ants can’t form a stable raft because the “Cheerios effect” of fluid ...
The term comes from the Greek γυνή (gynē) 'female', ἀνήρ (anēr) 'male', and μορφή (morphē) 'form', and is used mainly in the field of entomology. Gynandromorphism is most frequently recognized in organisms that have strong sexual dimorphism such as certain butterflies, spiders, and birds, but has been recognized in numerous ...
Solenopsis invicta, the fire ant, or red imported fire ant (RIFA), is a species of ant native to South America. A member of the genus Solenopsis in the subfamily Myrmicinae, it was described by Swiss entomologist Felix Santschi as a variant of S. saevissima in 1916. Its current specific name invicta was given to the ant in 1972 as a separate ...
"Floating fire ant colonies can look like ribbons, streamers, mats, rafts, or an actual 'ball' of ants floating on the water." Sadly, if you thought boats would be able to keep you safe from the ...
