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 ...

[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.
A person typically encounters problems with fire ants by inadvertently stepping onto one of their mounds, which causes the ants to swarm up the person's legs, attacking en masse.

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 ...
The illness usually moves from person to person via “fecal-oral” transmission. You can catch it by consuming contaminated food or water, and it’s the leading cause of foodborne illness in ...
This is a list of the deadliest animals to humans worldwide, measured by the number of humans killed per year. Different lists have varying criteria and definitions, so lists from different sources disagree and can be contentious.
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 ...
