ant : any of a family (formicidae) of colonial hymenopterous insects with a complex social organization and various castes performing special duties — Webster
Ants are eusocial insects of the family Formicidae and, along with the related wasps and bees, belong to the order Hymenoptera. Ants evolved from wasp-like ancestors in the Cretaceous period, about 99 million years ago, and diversified after the rise of flowering plants. More than 12,500 of an estimated total of 22,000 species have been classified. They are easily identified by their elbowed antennae and the distinctive node-like structure that forms their slender waists.
Ants form colonies that range in size from a few dozen predatory individuals living in small natural cavities to highly organised colonies that may occupy large territories and consist of millions of individuals. Larger colonies consist mostly of sterile, wingless females forming castes of “workers”, “soldiers”, or other specialised groups. Nearly all ant colonies also have some fertile males called “drones” and one or more fertile females called “queens”. The colonies are described as superorganisms because the ants appear to operate as a unified entity, collectively working together to support the colony.
Ants have colonised almost every landmass on Earth. The only places lacking indigenous ants are Antarctica and a few remote or inhospitable islands. Ants thrive in most ecosystems and may form 15–25% of the terrestrial animal biomass. Their success in so many environments has been attributed to their social organisation and their ability to modify habitats, tap resources, and defend themselves. Their long co-evolution with other species has led to mimetic, commensal, parasitic, and mutualistic relationships. — Wikipedia
Myrmecology is a branch of entomology focusing on the scientific study of ants. Some early myrmecologists considered ant society as the ideal form of society and sought to find solutions to human problems by studying them. Ants continue to be a model of choice for the study of questions on the evolution of social systems because of their complex and varied forms of eusociality (social organization). Their diversity and prominence in ecosystems also has made them important components in the study of biodiversity and conservation. Recently, ant colonies are also studied and modeled for their relevance in machine learning, complex interactive networks, stochasticity of encounter and interaction networks, parallel computing, and other computing fields. — Wikipedia
Ant keeping is a hobby involving the capture, care, and observation of ants and ant colonies. — Wikipedia

Emerald predators: Ohlone tiger beetles reclaim...
on May 29, 2020 at 12:48 pm
For the first time in over a decade, endangered Ohlone tiger beetles roam a preserve near Soquel and await their chance to pounce on unsuspecting prey. Their metallic emerald bodies appear iridescent in the sunlight as they scurry across the bare earth.

Evolution has produced countless amazing life forms, but you need look no further than to the human body to find examples showing that evolution has also produced a number of poor constructions."The many flaws of evolution makes it impossible to believe in the theory of intelligent design," says Professor Glenn-Peter Sætre at the University of Oslo.

A pair of researchers at the University of Sussex in the U.K. has found that like many other creatures, ants store memories differently in their two brain hemispheres. In their paper published in the journal Proceedings of the Royal Society B, Ana Sofia David Fernandes and Jeremy Niven describe Pavlovian-type experiments they conducted with ants and what they learned from them.

A study published this week in Scientific Reports by researchers from Macquarie University Applied BioSciences reveals that Queensland Fruit Fly (Q-fly) can detect the presence of potential predators by smell. Incredibly, the study also found that Q-fly modify their behavior based upon this detection, adopting predator-specific responses.
Insects: Largest study to date finds declines on...

A worldwide compilation of long-term insect abundance studies shows that the number of land-dwelling insects is in decline. On average, there is a global decrease of 0.92% per year, which translates to approximately 24% over 30 years. At the same time, the number of insects living in freshwater, such as midges and mayflies, has increased on average by 1.08% each year. This is possibly due to effective water protection policies. Despite these overall averages, local trends are highly variable, […]
