The begonia is having difficulty with how wet the weather has been, which can increase the incidence of leaf spot diseases. Stop spraying. It's not a pest and those products can take out any number of beneficial insects as well.

The insect on the Morning Glory leaf is a young, nymphal stage of a type of good/beneficial predator bug called an Assasin Bug. They help control other pest insects. Here is a page about them: He did not make the hole in the leaf. It's impossible to know who did.

The Phylostica leaf spots on Maple leaves are not uncommon, especially in wet years.
