A mosaic of black panes and ivory veins cut sharp lines across the wings of the Parthenice Tiger Moth.
Like most Tiger Moths, the Parthenice Tiger has bold coloring and distinctive patterns, making it easier to identify them. The wings are covered in triangles of black windowpanes bordered in tan frames. A plethora of thin veins criss-cross the black shapes unlike the wings in other related moths like the Harnessed Tiger Moth. The hindwings reveal a shock of bright pink when wings are flat and spread open. Small black patches border these wings and a crescent-shaped black spot stands alone at the center edge of the hindwing. The salmon-pink abdomen has a line of black dots running down the 'spine' and black coloring on the ventral (belly) side as well. The black antennae have short fine lashes on them.
The larvae of the Parthenice Tiger Moth is toxic and are generally left alone by birds, small mammals, and other typical caterpillar predators. Covered in dark stiff hairs, the Parthenice Tiger Moth caterpillars eat the leaves of dandelions, ironweed, and thistle plants. They are not considered a pest insect. Two broods can be produced each year. Adults can be seen from early summer through early autumn. They are nocturnal, but are attracted to lights at night. Look for them in fields, parks, and at the edges of forests and woodlands.

Note: An insect's reach is not limited by lines drawn on a map and therefore species may appear in areas, regions and/or states beyond those listed above as they are driven by environmental factors (such as climate change), available food supplies and mating patterns. Grayed-out selections indicate that the subject in question has not been reported in that particular territory. U.S. states and Canadian provinces / territories are clickable to their respective bug listings.
Butterfly and Moth Anatomy
Antennae: Butterflies and Moths have a pair of antennae on the head used as sensors.
Head: The head is home to the insect's eyes, antennae, and proboscis.
Thorax: Home to the three pairs of legs as well as vital internal organs.
Abdomen: Contains vital internal organs such as the heart(s) and reproduction facilities.
Forewing: The upper, forward wing pair used for flying.
Hindwing: The lower, rearward wing pair used for flying.
NOTE: Butterflies and Moths are part of the Lepidopteran order as they share many similarities.
