In this paper I explore the value of invertebrates to human society. I
initially examine various ecological, utilitarian, scientific, and cu
ltural benefits provided by invertebrate organisms. I then explore the
extent of appreciation and understanding of these values among the Am
erican public. This assessment was based on a study of residents of th
e state of Connecticut, including randomly selected members of the gen
eral public, farmers, conservation organization members, and scientist
s. The general public and farmers were found to view most invertebrate
s with aversion, anxiety, fear, avoidance, and ignorance. Far more pos
itive and knowledgeable attitudes toward invertebrates and their conse
rvation were observed among scientists and, to a lesser extent, among
conservation organization members. I finally examine the motivational
basis for hostile attitudes toward invertebrates, particularly arthrop
ods among the general public. Important factors include the possibilit
y of an innate learning disposition, the association of many invertebr
ates with disease and agricultural damage, differences in ecological s
cale between humans and invertebrates, the multiplicity of invertebrat
es, the apparent lack of a sense of identity and consciousness among i
nvertebrates, the presumption of mindlessness among invertebrates, and
the radical autonomy of invertebrates from human control.
