Short black dashes seemingly cut into the wings of the Great Oak Dagger, creating a visual texture that may help hide them.

Like many Dagger Moths, the Great Oak Dagger is gray. Symmetrical black lines, or daggers, run down both forewings. One pair of these black lines sits near the upper 'shoulder' area, and one sits by the rear end. A third, curvy pair is in the center of the forewings, touching a faint white spot at the top. Two more marks split the bottom edges of the forewings in half. A checkered fringe lines all the wing bottoms. A wavy white line runs across the lower part of all the wings. A tuft of white hairs may be visible where the tops of the wings connect when flat.

The Great Oak Dagger caterpillar changes its colors and patterns after molting. At one point, it may be white and black, or white and orange with sparse, long hairs extending off the entire body. At other times in its life, it is green or completely white with red 'eyes' on its white head. Regardless of the life stage, the caterpillar feeds on the leaves of oak trees, though not significantly enough to harm the tree.

Great Oak Daggers have a range that covers the entire continent, just like their host tree. Two broods are usually produced each year. Adults are active all of summer and are nocturnal. Artificial lights at night can lure them into areas for evening viewing.©InsectIdentification.org

* MAP NOTES: The territorial heat map above showcases (in red) the states and territories of North America where the Greater Oak Dagger may be found (but is not limited to). This sort of data is useful when attempting to see concentrations of particular species across the continent as well as revealing possible migratory patterns over a species' given lifespan. Some insects are naturally confined by environment, weather, mating habits, food resources and the like while others see widespread expansion across most, or all, of North America. States/Territories shown above are a general indicator of areas inhabited by the Greater Oak Dagger. Insects generally go where they please, typically driven by diet, environmental changes, and / or mating habits.
