Range & Habitat:
Our commonest Spiketail, it is found throughout the state,
although it has yet to be recorded in a few central counties.
Forested streams and rivers where it patrols steadily along
the edges for long distances. Found along larger streams
where other Spiketails are absent but may overlap with them on
smaller streams as well.
Large and black or dark brown, with a double row of bright
yellow spots on the top of the abdomen and bold yellow stripes
on the thorax. The Delta-spotted
Spiketail is similar but the spots are widely separated.
The uncommon Tiger Spiketail is
superficially similar but each segment has a nearly complete
yellow ring that may be broken dorsally.
Arrowhead Spiketail has single
spear-shaped dorsal spots.
River Cruisers are superficially similar but have a single
lateral thoracic stripe and different behavior.
Conservation Status:State: S4 - Apparently secure in New Jersey
Global: G5 - Secure globally, but possibly rare in parts of its range
