Over 15 years ago, researchers found that insects, and fruit flies in particular, feel something akin to acute pain called “nociception.” When they encounter extreme heat, cold or physically harmful stimuli, they react, much in the same way humans react to pain.
Do insects feel pain like mammals?
Although these neurons in invertebrates may have different pathways and relationships to the central nervous system than mammalian nociceptors, nociceptive neurons in invertebrates often fire in response to similar stimuli as mammals, such as high temperature (40 C or more), low pH, capsaicin, and tissue damage.
Do flies cry?
They were, it seems, emotionally stressed. A similar experiment printed in Current Biology in 2015 concluded: “Our results suggest that flies responses to repetitive visual threat stimuli express an internal state … More remarkable than the screaming was the apparent distress of another fly at window pane.
Do flies get mad?
Recently, biologist David Anderson set out to learn whether flies, like bees, can get angry--part of a broader effort to study how animal behavior relates to genetics. Every time you swat a fly away from your hamburger, it seems to come back to the food more aggressively or persistently, Anderson said.
