Identify little green long legged bug
The photo is not high quality, but the shape and size of the insect definitely point towards it being the nymph of some species of assassin bug (order hemiptera, family Reduviidae).
See this as an example:

Specifically, your specimen looks similar to one found in a home in Virginia.
The genus is likely Zelus, and based on it's greenish hue, I'd say it's an individual of the eastern US's most common species of Zelus, Zelus luridus (Pale Green Assassin Bug).

Nymphs are solid green, wingless, and with narrow bodies

The most reliable feature to distinguish this species from others is the pair of spines on the rear corners of the pronotum. These spines are long on the lighter colored individuals and shorter on ones that are darker. It can also be distinguished by dark bands on the distal ends of the femurs, but these can often be too light to be easily seen. [Source].
