Japanese beetles are a threat as well as scale, aphids, whiteflies and more. Yours appears to be a mottled tortoise beetle and favors morning glories. The best way to get rid of them is to pick them off by hand and drop them into a bowl of soapy water. If a pesticide is needed, permethrin can be used, but it will kill the beneficial bugs, too. For a less toxic option, you can try Neem oil or insecticidal soap.
