Differentiating between dead and living insects is accomplished by detecting their chemical signature. Depending on the species, this can be communicated by either the absence of chemicals that are present when they are alive, [11] or by those released in decaying corpses. Experiment have sought to identify how ants identify corpses that need ...
Most humans can withstand many stings, but others may suffer from severe reactions such as anaphylaxis. [45] People who are stung by red imported fire ants may experience intense local burning or flare-ups, followed by reddening of the skin at the sting site. This area will swell into a bump, hive or vesicle within 20 minutes. White fluid ...
A few individuals are sensitive to the venom, and can, on rare occasions, die of anaphylaxis. [3] In a survey of 29,300 physicians in the United States of America (in 1989), reports of 83 fatalities were obtained. [4] Some fire ant attacks on humans confined to beds have also been noted; in some locations, fire ants can be a particular threat ...
How far ants will travel for food depends on the species, but it’s generally within about 25 feet of the nest. The colony is almost always found outside, so look around to identify where they ...
For centuries we have believed that humans were unique in our ability to farm and cultivate our own food. However, it turns out that ants grow their own food too. Have you ever seen a trail of ...
Leafcutter ants have very specific roles in taking care of the fungal garden and dumping the refuse. Waste management is a key role for each colony's longevity. The necrotrophic parasitic fungus Escovopsis threatens the ants' food source and thus is a constant danger to the ants. The waste transporters and waste-heap workers are the older, more ...
Meat-eater ants feeding on a cicada: social ants cooperate and collectively gather food. Not all ants have the same kind of societies. The Australian bulldog ants are among the biggest and most basal of ants. Like virtually all ants, they are eusocial, but their social behaviour is poorly developed compared to other species. Each individual ...
Even during food processing, there are several procedures that strip foods of their poisons to make them human-friendly. Check out the slideshow above to learn what common edible contains cyanide ...
