Explanation of Names
Author: Packard, 1873
Similar to I. palustris.

Frans Janssens states: "In I. palustris there are, in addition to the middorsal stripe, two additional bilateral stripes present."

In a later comment, he expands on this statement:

"Note that the bilateral 'stripes' of tricolor:

1. are only present in well pigmented adult specimens
2. are only partly distinct as stripes: only on the abdominal segments, the bilateral pigment is stripe-like. On the thoracic segments the bilateral pigment is absent. Note that the coxae are pigmented, not the thoracic tergum.

In palustris, the bilateral stripes are from thorax to abdomen and distinctly on the terga.
