A Quick rundown on the season so far

Well what a whirlwind of a summer! After waiting through 5 tense weeks of rain, finally it has stopped. I just hope it picks up a little. Now the garden at home is too dry. Got through the rain wondering, where are all monarchs? I guess they were waiting to lay their eggs. Now it is eggapalooza!
The season started slow with only finding a few eggs to collecting 30-60 daily at work and home. I have to thank my seasonal works who are getting into the conservation thing and actively looking for eggs for me. We have milkweed at almost every park and facility where I work and so that makes collecting easy. I did this by design but also from an educational standpoint. Our facilities (park district) have kids and moms and dads going in and out all day, not to mention day camps! I want those kids visiting to say, I saw a monarch butterfly lay her eggs today at camp! We have a wonderful Naturalist that works with us and she does the bulk of the education. So anywhere I can help that out, make it more convenient.... I grow all the mw we use in the parks in our greenhouse so it is all pesticide free.
Oh and the nice garden club lady who dropped off a caterpillar, thank you. It will be well cared for by little Gwennie.
At home where I  raise these eggs into butterflies, is a little chaotic right now. We are in the tail end of a renovation project and I have no tables in the house. I can't wait to get my dining room up! I need a project space. The hatching boxes where the eggs go are literally on the kitchen floor.
When I bring eggs home, I  "process" them. By this I mean that I get a clean hatching box. I clean with bleach and make sure to rinse and dry well. I then place a paper towel in the bottom of the box and spray it with a little spray bottle. Make the paper towel a little damp.  The reason for this is too keep the eggs alive until the eggs hatch. After I get them all into the boxes, I count them,  make sure any funny looking ones get closer inspection with a jeweler's loupe.

Any bad eggs go out. I make sure there are no aphids or anything nasty on the leaves. Then I seal the box. This is important. Seal the box, make a hydration chamber so leaves live. I also open and close those boxes at least once a day to get fresh air in. You will want to see if they are hatching anyway.  And then you wait. When they start hatching, after 2-4 days,  I start putting new food in. Wash the leaves off and pat dry. I don't always transfer every tiny cat. to a new leaf. That would be too time consuming for the numbers I am taking care of. However when I had less than 100 I would definitely transfer them. I use the tip of a toothpick. Some use a paint brush.
Feed the cats and clean the boxes daily. Period. If you do not want a bacterial outbreak and cats dying, cleanliness is the most important aspect of this activity.
For my operation, when the cats get about an inch or so in length I think about taking them out to the caterpillar house. This is a structure built by my husband, Lee. It took him about 20 hours to build and believe it not, he used no plans. We deconstructed the old cat. house and there was enough wood there to reuse into the new one. He only had to buy a little bit of wood.
While out in the cat. house the cats are fed from large cuttings of common and tropical mw. They are in vases that are weighed down with marbles and the opening of the vase is covered with plastic wrap to keep cats. from falling in and drowning.
Then they just do their thing. Eat until it is time them make their chrysalids. They wander around the cat. house for a while and settle in a spot. When they eclose, I release them the same day.
So why do I do this, all of this? I definitely have enough to do over the summer. I work full time, lecture at garden clubs, but only a few in the summer. I have a large garden to take care of and other responsibilities.
I don't want to get all sanctimonious about this and say that I am going to save this species. I have genuine sympathy for the monarch and their plight. I do this because the symbolism of the metamorphosis is important for me. I think that this species is a good ambassador for all the insect world and why we should protect them. Except aphids. I don't like aphids. Oh and mosquitoes...oh well. Most insects are really cool and beautiful. And I do it because it is fun.  Although this week it is feeling like a job. :)
Next up I will address those insects that also use mw for their home.

This is what I call a Family Tree!

What a family tree!

*I just want to say thanks for all the sweet email & fb messages about the butterflies. I truly enjoy this, however my slightly obsesive personality has gotten a hold. If I go out to visit the caterpillar house I find that and hour or more has passed since I opened that door :). I am happy to share this with you and it makes me happy that you are all enjoying the experience too! *

Now back to regularly scheduled programing....

I was out this morning checking in with the cat. house. There were 9 butterflies yesterday and 11 today. The tally for released butterflies is 137 give or take a few, I don't have a completely accurate number for Friday the 20th. I guess I was in too much of a hurry ... But I digress. The egg laying has slowed down this week in my garden and I think it may have something to do with the yucky aphids. I blasted off all the critters with the garden hose. Not as easy as it sounds! I had to cup the tops of the plants in my hands and blasted them. now multiply that by 12 plants, some with multiple branches. I got a couple of funny looks from the nieghbor- whatever man! It did not take very long. Consequently my arm was covered in creepy crawlies- shudder- So the egg laying has stalled at 520 and the butterflies should be turning around and starting the journey to Mexico very soon. The egg laying doesn't surprise me. I did say that I would just collect until I couldn't find any more eggs, so we'll see what this week brings.


I have found that this little project for the summer takes some time to attend to. Caterpillars eat- a lot- and with eating comes the pooping...They poop a lot! As they get larger so does the poop. Sometimes I can't even see a caterpillar when they hatch from their egg, except for the little hole they eat in the leaf and the tiny dust-like poop. As they grow- so does the poop! If you don't clean the boxes you keep the cats. in before they go into the cat. house, the poop can contamiate everything and the little guys begin to die. I lost 3 cats. today because I was pretty distracted yesterday and thought everything was ok. When I opened the boxes today I found a lot of moldy leaves and I had to search for the very smallest cats. If you decide to jump into this for next summer just remember that you have germs and so do the cats. so wash your hands before nad after handling.


I watched 4 caterpillars pupate (make their chrysalis) this morning and I again missed 3 butterflies emerging. Darn! I keep missing it. That must go very quick. When the butterfly emerges its wings are wrinkled and its abdomen is very swollen. The fluid inside the abdomen is the gently pumped into the wings to expand them. The butterfly then chills out for the next few hours waiting for their wings to harden and they test them out flapping every few minutes until they are strong enough to fly.

They will feed soon after they beging flying. During the first part of summer and spring, the butterflies will mate and females lay about 500 eggs over a couple of weeks and then live a couple more weeks after that. I did mention earlier that the monarchs butterflies emerging at this time in the summer go into a period of diapause- they put off mating until next spring when they begin the journey north and then they will die. So this generation will live about 9-10 months.

Aug. 8th Update on the Monarchs

monarch on native cup plant
Today the highlight was not so much releasing butterflies but the number of eggs that I have collected in the past few days. I collected 50 eggs in the past 2 days. This morning my friend Zahida came over and after looking at the caterpillar house we immidiately began looking for eggs to take home with her. We found 10 eggs and 1 caterpillar! Later in the day my sister stopped by and we found 7 more! Then I went our just before dusk (after the butterflies are fininshed for the day) and I looked on all of the pmonarch eggs on a tiny leaflants and found- get ready for this- 26 more. I even found 2 tiny eggs on one very tiny leaf. The picture is right there, that is the whole leaf.


This is getting big. The tally is 358. We released only 2 butterflies today but there are about 35 chryalis' out there. I should have many to release later this week. Unfortunately I did have 3 chrysalis' that should have hatched but they all had "the black", a bacterial infection that kills the developing buttechrysalis' with 'the black'rfly. It appears in a percentage of caterpillars and developing butterflies. Just a fact of life. The majority of the butterflies should develop normally.

Cute pictures of caterpillers & update!

I collected eggs today with my nephews and niece! Thanks Julia, Steve & Andy! With the extra sets of eyes, I think we found all of the eggs fromtoday. We found 31 eggs! There was one Monarch hanging around the garden and when a second one wandered in they were sparring in mid air! The males are very territorial! ~ the egg tally is now 314! I released 2 butterflies today. So my total is 56! I took a

Well my internet has been wonky for a few days so there is a lot to report! Since my last update I have been collecting more eggs at work and home. The caterpillar and egg count is now up to 203!!! I never, never thought I would ever find that many eggs! I have even found 3 swallowtail bytterflies on the one curly parsley plant I have. Alas I cannot find their chrysalis'.



But I digress...So 203 eggs but the real results will be when I release the last butterfly for their journey to Mexico. Yep folks, these butterflies are the last generation to be hatched here and they will put off mating until they reach their overwintering forest in Mexico. Normally only 10% of the eggs laid will mature into butterflies but when people take them in and rear them indoors there is a much hight success rate.

Tonight there are 40 chrysalis' and I think 2 will hatch tomorrow. I just added 7 more 1 inch caterpillars to the caterpillar house yesterday. So in the boxes in the house I have many many caterpillars in differing stages and lots of eggs. So when I add caterpillars to the house I fill it up with more new eggs! more news tomorrow...

Caterpiller Mania!

monarch caterpillars




The caterpillar house is getting full! There are about 35 little guys in there eating away! The egg + caterpillar count is 170! I have released 13 butterflies. I have noticed that the caterpillars that have been living outside in the caterpillar house eat more, longer and grow much larger than the ones I have raised totally indoors. Hmmm.....
