Spiketails are black and yellow colored and they have tear-shaped blue eyes that barely touch each other; the thorax has two wide, yellow stripes on the top and on each side; they are found on moving water and fly beats up and down the course of the waterway.

Cruisers (Macromiidae)
Of the 2 species found in Mexico, only 1 species has been documented in Jalisco and none yet in Nayarit.
Cruisers are also black and yellow but they have gray eyes that touch each other but don't form a "seam"; they have a single yellow stripe on the thorax side; LONG legs; a body that is arched in powerful flight; they are found along rivers and large creeks. They usually hang perch on vegetation, perpendicular to the ground.
