Frogs usually forage in the evening, but during the day they need to keep their skin moist and cool. To do this they hide in the foliage that surrounds their hunting grounds. So if they come out to get bugs around your porch lights at night they will most likely be hiding in the nearby vegetation during the day.
Green tree frogs, and squirrel tree frogs, (the bright green guys) love porch lights. Unlike toads they have grippy toe pads that allow them to hunt on vertical surfaces. So, at night they climb up and down the outside walls of homes, in and, around the porch lights hunting for moths and other flying insects attracted by the light.
Plants that have broad leaves, and a lot of leaf surface area, provide daytime resting sites for frogs in the home landscape. Actually, whatever plants are around the foundation of your home will do, but these are especially attractive to frogs.
Plants such as string lilies (Crinum americanum), southern blue flag (Iris virginica), and canna lilies (Canna flaccida), have long broad leaves that hold and retain moisture which makes perfect shelter for frogs that are looking for moist foliage to wait out the heat of the day.
Frogs also like to hide down inside the center of large flowers like azaleas (Rhododendron spp), lilies, or amaryllis.
