If you go down to San Diego today you could be in for a big surprise . Creeping out of pickle and cracks in Southern California are two mintage of tarantula that are setting off for their annual union ritual .

The California black tarantula ( Aphonopelma eutylenum)and the San Diego bronze tarantula ( Aphonopelmus reversum ) are the two species in question – and while neither is specially dangerous to human race , they can both present a nasty bite and have hair that will irritate the skin .

Rural area such as El Cajon , Ramona , and Poway may be particularly affected as potentially thousands of these tarantulas appear and begin looking for love .

" Around this time , it ’s like clockwork – right around the middle of August . There are two species of European wolf spider in San Diego , and both start their mating season . aright around this time is when the male person are leave behind their burrows and they ’re set out to look for females , " said Cypress Hansen , Science Communications Manager at the San Diego Natural History Museumin a command in CBS8 in 2022 .

Males are most likely to be roaming the streets but may not endure this summer of love as they are now and then eaten by the female person after mating . Female tarantulas will make silk cocoons for the eggs which could be laid in numbers pool up from 75 to 1,000 . The female will even guard the eggs for around 8 week until they hatch .

To get to that distributor point though , the male will tiptoe into the underground den of the female person and attempt to transfer sperm to her using his pedipalps . “ They use this glove - same setup to dispel sperm , and then it deflate like a balloon . After laying down a layer of sperm over silk web , the male head for the hills – because if he hang around , the female will commonly eat him . " Forest Urban , manager of the invertebrate program with the Natural History Museum of Los Angeles toldthe Guardian in 2019 .

Female tarantula can survive as long as 25 years in the correct conditions , while males typically survive only 5 - 8 age – they typically give-up the ghost around six months after felt up .
