So let us begin. We have chosen a pair of
Ornithoptera priamus for today, as they are nice and big and relatively
easy to set. We are going to work with the male as it is nice and
colourful and a good size to photograph while we work. Now I must
stress that we are about to show you two basic ways to relax your
specimen/s (one slow and one fast) there are different methods which you
may wish to adopt at a later date, but we find our second method by far
the best. |
RELAXING - METHOD 1 (Slow)
|
|
Line the inside of your relaxing
container with several layers of toilet tissue and dampen with water from
the mist sprayer. DO NOT SOAK, only dampen the tissue. You only want to
provide a damp atmosphere inside, not a soaking wet one. You may just wish to place your specimens in the relaxer still in their
triangles. If you do then spray the outside of the triangle with a very
light mist of water from your sprayer. You only want to slightly dampen
the paper, not soak it. OR:
|
|
Unwrap your specimens from their paper triangle. Taking care not to break
them., and place them in your relaxer. If you do this, DO NOT SPRAY
DIRECTLY ON TO THE
SPECIMENS. Don't forget to keep a record of any collecting data on the triangle, as
this is important later. You will want to know where and when your
specimens were collected. Sometimes the written data on the triangle will
"run" or fade or just plain disappear, when it gets damp, and
you may not be able to read it later.
|
|
You may also need to place some anti-mould crystals in the relaxer, to
stop mould forming on your specimens. Paradichlorobenzene or
Thymol, is good for this. Just a few crystals is enough. Small specimens, like Lycaenidae or small Nymphalids may take around 24
hours to relax. But some large specimens may take several days. You
must check your specimens periodically to see when they are ready. I personally don't like this method. I seldom have the time or the
patience to wait for the specimens to be relaxed, and the longer you leave
material in the relaxer, the more chance you will get water stains on
them.
NOTE. However, this method of relaxing is very good for Beetles.

RELAXING - METHOD 2 (Fast)
|
|
Firstly, unwrap your specimens.
Then fill your mug with boiling water, and fill your hypodermic syringe. Hold
the specimen by the thorax between thumb and forefinger, and insert
the needle at the rear of the thorax. You may have to wiggle the needle a
little bit to work it inside, as the specimen is very dry at this stage.
Depress the syringe, gently injecting water inside. Let go of the specimen
when you do this as you may burn your fingers with the hot water.
|
|
As you inject the water you will feel the inside of the
specimen start to soften already, as the dry insides start to take up
moisture and relax. Keep on gently injecting the water until it starts to
dribble or squirt out of the thorax. On large specimens you may to have to
use several syringes full of water. Do not inject under too much pressure or you will
send the insect flying off the needle, and you don't want that to happen
do you. Make sure you give the insect a quick shake to flick off any
excess water droplets. Then.
|
|
As above, line the inside of your relaxing container with several
layers of toilet tissue and dampen with water from the mist sprayer. DO NOT SOAK, only dampen the tissue. You only want to provide a damp
atmosphere inside. Not a soaking wet one. Place a layer of fine paper on top of the tissue. This will just
keeps the specimen out of direct contact with the damp tissue.
|
|
Now put the lid on and leave for 5 - 10 minutes. Then check and make sure
that there is no evidence of too much water on the specimen. If you notice
any just dab it up with some tissue. Put the lid back on. In most cases your specimen will be ready to set on your board within
an hour or so and after you have gained some experience and relaxed
material from a few different families you will get a
"feel" for when they will be ready. A basic rule of thumb for relaxing times are:
1/2 hour for small specimens like Lycaenidae, and small Nymphalidae etc.
1 hour for medium Nymphalidae and Papilionidae, etc.
1-2 hours for large species like Ornithoptera.
