pete could you help me distinguish this from a Tiger Spiketail for future observations? Is there a quick way to visually discern this?

Spiketails and cruisers have similar yellow-on-black patterns, but cruisers have 1 lateral thoracic strip, while spiketails have 2 stripes. Cruisers are usually found flying continuously over larger creeks and rivers, while Spiketails tend to alternate between hovering and moving, and are usually found over small streams and seeps. Here is a good web page for learning the differences between ode families: http://www.odesforbeginners.com/family_guide/fam_spiketails.aspx
