Attraction of moths to light

[Dr. James Adams]

One more quick comment,

    Someone asked about the visual acuity of moths.  Although moth 
eyes are very sensitive to dim light, it is unlikely that any but the 
brightest stars are actually "seen" by the moth, though the research 
in this area is extremely thin.  The sky at night (without the moon) 
is probably seen as just a lighter background than the ground below 
and objects around them, enough to navigate around objects and help 
keep themselves oriented appropriately in the up-down plane.  Anybody 
out there know more about the visual acuity of moths??
