Regal jumpers, a type of jumping spider, appear to be less interested in
each other if they have met before, suggesting that the arachnids recognise
individuals within their species
Some evolutionists
believe that Jumping spiders seem to be able to tell each other apart, putting them
among just a few other invertebrates that are thought to have this kill.
“Recognising individuals within
your species is important for social animals, such as primates, but just a
handful of invertebrates have been observed to have this recognition, for
example Northern paper wasps (Polistes fuscatus). This is thought to help
with social cohesion within the insects’ colonies.!!”
