The bases for forensic entomology are that insects and their arthropod relatives
can serve as evidence in criminal, medical and civil legal matters. However, some
of the very same species that provide utility to legal investigations can also
complicate crime scenes by distorting existing body fluid evidence (e.g.,
bloodstains, semen, saliva) and/or depositing artifacts derived from the insect
alimentary canal at primary or secondary crime scenes. The insect contaminants
are referred to as insect stains, artifacts, specks or spots, and are most
commonly associated with human bloodstains. This review will discuss the
different types of insect artifacts that have been described from crime scenes
and laboratory experiments, as well as examine insect contaminates (non-blood
based artifacts, transfer patterns, meconium, and larval fluids) that have
received little research or case attention. Methods currently used for
distinguishing insect stains from human body fluids will also be discussed and
compared to presumptive tests used for identification of human body fluids. Since
all available methods have severe limitations, areas of new research will be
identified for the purpose of development of diagnostic techniques for detection
of insect artifacts.
