Over 300 volunteers have tagged monarchs throughout the southwest. Lee MacDonald and his mother, Victoria, joined us on a tagging trip at Canelo, Arizona.
In this photo, Lee proudly shows the two monarchs to be tagged that he captured with his bare hands!

First Things First!
Do you know what a Monarch Butterfly looks like? Both Queen and Viceroy butterflies look similar to
Monarchs and are easily confused. Click here

Now you are ready to begin! Here are four easy steps:
Step 1: Finding Monarchs! If you have a school or home garden, look for broad, flat flower heads.
These provide stable landing pads for butterflies. Sunflowers, tithonia, milkweeds, thistles, lantana, mints and verbena are usually popular
with butterflies. They also love rabbitbrush and desert broom during the migration. Monarchs are opportunists, so be sure to check all
flowering plants. The best time of day to find monarch butterflies is
in the morning and the late afternoon on sunny days.
Monarchs are sun-powered and favor temperatures above 55 degrees. Calm or light winds are best.
Step 2: Catching Monarchs It’s exciting to tag a monarch for the first time. When you see one, think for
a moment of the best way to catch it.
Chasing a butterfly with a net and swinging wildly at it usually doesn’t work!
Instead, move slowly (moving fast can scare it away).
Monarchs can’t see backwards, so sneak up behind it. Try to put your net underneath the butterfly. In a fast sweeping
movement, move your net upward to catch the butterfly, then quickly flip your net over so that the opening is now facing down.
If you have flipped quickly enough, the net will fold over, trapping the butterfly in the end of the net.
Step 3: Handling Monarchs Place the opening of the net flat on the ground and slide your hand under
the hoop and into the net. Gently trap the butterfly in the net so that its wings are folded (as opposed to open).
Grasp the leading edge of the folded front wings between the thumb and forefinger and carefully remove the butterfly from
the net. Remember, the butterfly’s wings are covered with powdery scales. If too many are rubbed off,
it could affect its ability to fly.
Step 4: Tagging Monarchs As you hold the butterfly, have a partner record the requested information
on the SWMS datasheet. Next, have your partner remove a tag from the tag sheet and carefully apply it to the discal
cell on the hindwing of the butterfly. (See photo) Press the tag and wing gently between your thumb and finger to force the adhesive
through the scales onto the wing. Be sure to record the tag number on the data sheet! After you double check that
you have recorded all the necessary information and you are comfortable that the tag is secure on the monarch, place it
on the same plant or a similar one where you originally found it. The monarch may fly off immediately or rest for a few
moments before continuing on its way.
