Should I rebuild the exception in this case?

Question

Is this approach appropriate? Am I handling exceptions correctly? See My class:

class Email extends String
{
protected function validate($email)
{
    try{
        parent::validate($email);
    } catch(InvalidArgumentException $e) {
        throw $e;
    }

    if(!filter_var($value,FILTER_VALIDATE_EMAIL))
    {
        throw new InvalidArgumentException('etc.');
    }
}
}

If you are not going to do anything with an exception in this catch block, there is no need to enclose the call to the parent method in your own try-catch block. The method automatically passes an exception from the parent implementation if it encounters one outside the try-catch block, just as if you had selected an exception from the same context (as after the if condition):

protected function validate($email)
{
    parent::validate($email);

    if (!filter_var($value, FILTER_VALIDATE_EMAIL))
    {
        throw new InvalidArgumentException('etc.');
    }
}
