Spiders that hunt at night often have a special layer at the back of their big eyes. It acts like a mirror to bounce light back into the eyes. On a dark night, this reflected light makes the spider's eyes seem to glow!
"Bug Lady"
"Bug Lady" Professor Gail Anderson of Simon Fraser University
has been named on of the five leading innovators in the field of
criminal justice by Time Magazine. Prof. Anderson is a forensic
entomologist and a criminologist, and she uses insects to tell the
time of death in a homicide. By researching the patterns and stages
in which insects colonize a body after death, she can determine
when death occurred, sometimes to the hour! MARCH 13, 2001
