DISTRIBUTION:

The Catocala aholibah moth (wingspan: 80-90mm) flies from British Columbia south to California east to Arizona and north to Colorado.

David Wikle has taken them at Cloverdale Muni Airport, Sonoma County, California, 24 August 2003.

Canadian records also exist for Saskatchewan, so I suspect there are flights in Alberta as well.

protibiae (lat.) laterally without spines
midtibiae spine-like projections present
hindtibiae spine-like projections present

Aholibah lacks the bar paralleling the forewing inner margin of allusa. Aholibah also has a dark arc running from the costa along the antemedial line, below the subreniform spot through the two upper jagged "teeth" of the postmedial line.

FLIGHT TIMES AND PREFERRED FOOD PLANTS:

Catocala aholibah are usually on the wing from mid June to early October.

The Catocala aholibah caterpillar shows a preference for Quercus species: agrifolia, alba, gambelii and garryana.

ECLOSION:

Adults eclose from pupae at soil surface.

SCENTING AND MATING:

Catocala aholibah females emit an airbourne pheromone and males use their antennae to track the scent plume.

EGGS, CATERPILLARS, COCOONS, AND PUPAE:

Eggs are deposited on tree bark in the fall and hatch the following spring.

Mature larvae, commonly found in May and June, are grey with a slight rosy hue. There are single tubercles on the fifth and eighth abdominal segments. Image courtesy of Jeff Miller from Caterpillars of Pacific Northwest Forests and Woodlands.

Camouflage is remarkably well-developed for most of the Catocala species, in the egg, larval and adult stages. Despite their large size, larvae easily blend in with bark of twigs and stems where they hide during the day. Jeremy B. Tatum writes, "I once had a full-grown one sitting on a single, unbranched twig, and held it a few inches in front of several colleagues, who were quite unable to see it. When discovered, however, the caterpillar can jump!"

Pupation is usually at or near soil surface under litter or debris. Pupae shortly develop a bluish white "bloom" as shown in the image to the right courtesy of Jeremy Tatum and Dr. John Snyder.

Larval Food Plants

Listed below are primary food plant(s) and alternate food plants. It is hoped that this alphabetical listing followed by the common name of the foodplant will prove useful. The list is not exhaustive, although some species seem very host specific. Experimenting with closely related foodplants is worthwhile.

Quercus agrifolia..... Quercus alba Quercus gambelii Quercus garryana

Live oak White oak Gambel oak Garry oak/Oregon white oak
