Delta beldum spider

I am in the Murk forest but I do no know how to get delta beldum spider? I see a blocked path but cant get past it?

Have you beaten all the ariados?The use heart swap on the manaphy statue,and you will be able to jump on the small meteors.

And to activate the event,talk to the hiker in hekate town.He is running in front of route 13’s entrance.Bye.

No where are they? I didnt see any Ariados in Murk forest but I will try to talk to hiker, thanks :smiley:
