Does catch exception by reference need to be deleted?

I'm creating a customized exception class

class my_error: public std::exception
{

public:

    //! Constructs parse error
    my_error(const char* param_msg, std::string param_reason) throw()
    {
        msg = param_msg;
        reason = param_reason;
    }
    ~my_error() throw() {}

private:
    string msg;
    string reason

};

and throw it with this way

throw my_error("something wrong", "coffee is too hot");

and catch with

catch(ems_error& ex) { 
// do somehitng here 
}

question: should i call delete on this ex variable? currently my program works fine without delete but I'm worry abbout memory leak

Exception objects are automatically destroyed after being handled. (See C++11 §15.1/4)
