Ten
reasons for collecting and preserving insect specimens
There is
an increasing trend to discourage collection and preservation of biological
organisms including insects and their relatives. Although insects can
be studied and enjoyed without killing them using observation and photographic
methods, there are a number of reasons or benefits from procuring specimens:
1. Identification
of insects is a specialty within the study of insects (entomology)
based on studies by taxonomists that describe species or groups of
species (e.g., families, orders, genera, etc.). Through collection
and preservation efforts, new species are found and described. Many
undescribed insects remain in the world, even in Texas.
2. Properly
preserved and stored insect specimens can be enjoyed and studied for
hundreds of years while most insects live only for a period of days
to months before they die and decompose. Specimens in museums, along
with the data provided on the specimen labels constitute an historic
record of biological diversity and can be used to document changes
in distribution and abundance of species over time. Some museums contain
specimens of now-extinct insect species.
3. Names
and identities of insects (and other organisms) change over time when
new studies reveal the need for a name change. If specimens were used
as the basis for a scientific study on, voucher specimens are submitted
and stored in a recognized, reputable insect collection. Only then
can researchers in the future double check to make sure the species
cited in these studies were accurately identified. In some cases, specimens
that looked identical to early researchers are later found to actually
represent two or more species through further study or use of new techniques.
4. Insects
are the most common form of wildlife encountered by people and are
excellent models of living systems useful in learning about several
fields of science. Most species are common and abundant and are not
threatened by casual collection activities. Close observation of preserved
specimens can result in an understanding of form and function of bodies
(morphology and behavior), relationships between organisms or groups
of organisms (systematics and evolution), methods of identifying organisms
(taxonomy), and life cycles (developmental biology).
5. During
the exercise of collecting insects, collectors learn about relationships
between insects and their environment, the importance of habitat, keys
to species survival, and the relationships between species groups such
as hosts, predators and parasites, i.e., trophic levels. Closer inspection
of predaceous insects, for instance, reveal adaptive features enabling
those species or groups or species to capture prey or what features
allow a walkingstick to mimic a twig.
6. The
study of insects in collections provides knowledge that can lead to
a better understanding and higher tolerance of this group of animals
in our environment. Ignorance about insects and their relatives can
lead to an irrational fear of insects, called entomophobia (fear of
spiders is arachnaphobia), or even psychological problems such as imagining
that your body is infested with insects (delusionary parasitosis).
Inability to determine beneficial insects (pollinators, predators,
parasites) from pest insects can lead to unnecessary pesticide (insecticide)
use.
7. Insects
and their relatives are fascinating creatures so unlike ourselves.
Yet they share many features with humans and other animals. People
of all ages can participate in the study of insects and making an insect
collection is an activity to be shared with others, providing enjoyment
and exercise while being educational.
8. Many
insect specimens are simply beautiful to the eye. Butterfly wings have
been called “nature’s canvas.” Other insects are
ugly and horrifying to look at. When mounted and displayed properly,
insect specimens or insect parts can become an art form similar to
taxidermists that display stuffed animals or artists using paint to
make a picture.
9. Insect
specimens make great souvenirs. Assuming laws and regulations pertaining
to the collection and transport of biological specimens are honored,
specimens collected on vacation trips can make useful reminders of
these trips to far-away places. Properly maintained, the specimens
can last more than a person’s lifetime.
10. Making
insect collections, particularly bug hunting expeditions, are really
fun! In a sense it’s like a real hunting trip, except you do
not need guns or hunting licenses (with exceptions in some park lands).
It’s generally a lot cheaper, too! Going bug hunting as an adult
can even make you feel like a kid again. |
