Let it draw you in.(If you escape without doing anything try getting closer to it)

Free yourself.

Put on Ghillie.(And bug repellant to not get annoyed by swarms)

Give it some Parasaur to eat.(Increases effectivity)

Remove ghillie.(Again bug repellant)

Let yourself get webbed with Blood bags in your inventory.

Done

Good Luck!(you also might need parachutes/grappling hook)
