Explanation of Names
Specific name scitula from Latin meaning "beautiful."
Body length about 10 mm; wingspan 14-20 mm; forewing length 5-9 mm. (1), (2)
Larva to 15 mm. (3)
Adult - steely-blue or black body with thin yellow band on second abdominal segment, and wider yellow band on fourth segment; rounded anal tuft on tip of abdomen (triangular or pointed in many other species); forewing transparent with dark outer margin.
Larva - body cream colored, reddish brown head and two similarly colored spots on the prothoracic shield. (3)
Southeastern Canada and eastern Unites States, west to Minnesotam Colorado and Texas. (4), (1), (5), (3)
Recently found in the Northwest. (4)
Deciduous woods, parks, yards, river floodplains.
Adults fly from March to September. (3)
Larvae bore into the largest number of host species amongst the Sesidae, including beneath bark of various trees and shrubs such as apple, bayberry, black cherry, blueberry, beech, birch, chestnut, dogwood, elm, hazel, hickory, mountain-ash, oak, pecan, pine, willow. A notorious pest of flowing dogwoods and pecans. (2), (3)
Life Cycle
One or two generations per year; overwinters as a larva beneath bark of living tree or shrub, and pupates in spring; pupa stage lasts 25 days, then adults emerge and eggs are laid singly in wounds on tree; eggs hatch in about 9 days and go through seven larval stages in galleries beneath tree bark; adult lifespan about a week. Young larvae very sensative to low humidity. (3)
They attack their hosts via abnormal growths, woody galls, excretions from fungus, rusts, blight, bruises, and healing wounds.(6)
Males attracted to (Z,Z)-3,13-ODDA pheromone lures (Meyer & Cranshaw, 1994).
A single larvae can kill a dogwood 4" in diameter in one year.(6)
