The
Gloworm
24 June 1994
Volume 2: no. 6
Wow, the summer has hardly
arrived and I'm already so covered over with things to do that I'm
sure that many will have to be forgotten until next year. This is the
first free couple of hours I have been able to find to try and put a
`Gloworm' together. We finished our Entomology Camp up on June 10. It
was a `big success', of course, I'm prejudiced about it. We spent
from Sunday afternoon until Friday noon, learning about insects and
hunting them. The big attraction at camp was that everybody wanted to
catch a STAG BEETLE. That became the battle cry for all the campers
throughout the week. Dr. Jerome Goddard told us on Sunday night that
he had collected and sold a stag beetle (male) for $37.50. So
everybody wanted to catch one and send it in to get rich. We did
catch 4 or 5 during the week, but haven't gotten the address from Dr.
Goddard, yet. Most of the campers went home with 40 to 50 pinned
specimens, with a much better understanding of insects, insect
collecting, and with about 30 new friends. We are already talking
about camp for 1995.
Last month I gave out some
incorrect addresses and information. BioQuip Products have moved to
17803 LaSalle Avenue, Gardena, CA 90248-3602; telephone 310-324-0620.
The entomological blacklight sells for $42.50 (DC), $45.00 (AC) and
$70.00 (dual AC/DC). I could not locate the new address for American
Biological Supply Company. Dr. Brown tells me that the DC light comes
equipped with a cigarette lighter like plug and that clips to fit a
battery must be purchased separately, (ca. $9.00). Black lighting is
adventuresome and fun.
Collecting Tips: At
times collecting is fast and furious, and we don't have time to wait
until one specimen is killed before another needs to be placed in the
kill jar. Multiple kill jars, about the size of baby food jars
(narrower and deeper jars are even better), work really well. Keep
them well charged with ethyl acetate, that's finger nail polish
remover, nonacetone type. Also, remember that an alcohol jar (ethanol
is best) can be use as a kill jar for almost all insects, except
Lepidoptera. When beetles and other insects dry out from their
alcohol bath they look as good as new and they don't become brittle
if they have to stay in the alcohol longer than a day or two. It is
important that specimens collected be processed as quickly as
possible. Always work them up being careful to apply correct Date,
Locality and Collector information to specimens as soon after
collection as possible.
Spreading boards and
pinning blocks are easily constructed using the foam poster board
which is available at most frame shops. Lepidoptera should be spread
within a day of collection, but if they dry out before they are
spread, they can be relaxed by placing them in a closed container
with a damp paper towel. Don't leave them that way more than a day or
so or they will mold and ruin. Spread the wings carefully on the
boards making sure that they are at the correct level to prevent
canting upward or drooping after they are removed from the board. Wax
paper can be used to cover and hold the wings in place while they are
drying. Pins can hold the paper down without penetrating the wings.
Use patience and take your time when working up a day's catch. That
can make all the difference in the world in the way a collection
looks.
Insects to look
for: As the summer progresses the more colorful butterflies
appear, looking for flowering plants from which they collect nectar.
Many are also looking for larval host plants for egg laying
(oviposition). A variety of plants will often attract a variety of
insects, so if you are planning a butterfly garden, plant as many
kinds of plants as you can. Tiger Beetles are also plentiful during
the hot part of the summer, but they may require some ingenuity to
find. They are often very active in sandy areas which are not
overgrown by vegetation. Larvae can be found in burrows in the sandy
soil. Velvet ants are often seen in the same general area. Pitfall
traps may be used to collect insects of this kind. Simply dig a
shallow hole and place a cup, usually two cups, one inside the other
work best, so that the lip of the cup is level with the soil line.
Add alcohol to the cup. Check the cup daily, removing the insects
which fall in and replenish the level of alcohol. Be sure and remove
the trap when you are finished. Dragon flies have been especially
plentiful this summer and are also fun to watch and to catch. Don't
go overboard with any single species, but look for
variety.
Enclosed in this issue are
some photocopies of Entomology Camp activities. I hope you enjoy
them.
Happy Bugging!
