I don't think there's a nice way for a factory to tell that it's been called by another without collaboration. (You can always inspect caller_locations, but that's not nice.) Instead, have one factory tell the other to behave differently using a transient attribute:

FactoryGirl.define do
  factory :user do
    transient do
      create_identity true
    end

    after(:create) do |user, evaluator|
      if evaluator.create_identity
        create(:identity, user: user)
      end
    end

  end

  factory :identity do
    association :user, factory: :user, create_identity: false
  end

end
