Bug Identification: Tiny Bugs in Fairport NY
These bugs are a type of hexapod called springtails (subclass Collembola). Springtails are often very tiny and hard to see without a lens, so I have to say you did a good job grabbing a fairly detailed picture of this one. Specifically, your specimen appears to be some species in the order Entomobryomorpha. 

According to Wikipedia:


  They can be best distinguished from the other springtail groups by their body shape...The Entomobryomorpha...contain the slimmest springtails [with]...long bodies. [They also have] well-developed furculae


Specific species:

Usually, IDing springtails is very difficult, but I believe your specimen matches a fairly widespread species called Entomobrya nivalis (aptly named the cosmopolitan springtail).

The description of this species matches yours fairly well. From Wikipedia:


  The cosmopolitan springtail measures about 2 mm in length. Its color consists of a yellow or white background with dark pigment forming transversal bands along the third segment of the thorax and the segments 2 to 6 of the abdomen. The fourth segment of the abdomen has a U- or 11-shaped pattern that easily distinguishes this species from others in the genus Entomobrya+


Somewhat true to its name, this somewhat cosmopolitan species is found in temperate and polar regions across North America and Europe+. Adults typically live among lichens and trees (whereas young live in leaf litter), however, according to NC State Extension:


  Rarely springtails may become exceedingly abundant and may congregate in heaps several inches high on driveways, sidewalks and poolsides.




So what exactly is a springtail??

In general, springtails usually feed on decaying matter, and -- you guessed it -- they're known for their ability to jump! 


  Springtails are so-called because they have a unique structure, the furcula, that allows them to jump for considerable distance relative to their tiny size. [source].
