Deciduous forests and open woodlands in close association with Carya myristiciformis
Flight period: June-August
Nutmeg Hickory, Carya myristiciformis
(see distribution map
of host), and possibly other spp. of Carya
is similar to unbarred gray form of myristica
, but the PM line of myristica
has darkened, thickened black scaling at parallel section of the PM line near inner margin, which is barely present in robinsonii
if at all. Also, the reniform spot of myristica
is noticeably more filled with brown scaling.
is similar to the barred form of myristica
, sharing the black bar that travels from the apex to the mid basal area. The two can be separated by the thicker, more intense, unbroken appearance of the black bar in myristica
, verses the thinner black barring often appearing nearly broken between the reniform and subreniform spot in the median area.
in its barred form is also somewhat similar to the barred form of myristica
, but more easily distinguished by its black barring having a distinct break in the median area at the reniform/subreniform spot.
