Raising Butterflies and Other Odds and Ends

        When I mentioned raising butterflies indoors in my last post several of you left comments expressing an interest  in knowing more about the process. I do not have pictures of the entire sequence, but I can explain what you need to know without them, and I think the narrative will be sufficient. After this post if you still have questions feel free to get in touch with me.
     The first thing to determine of course is the species you wish to raise and to ensure that you have their preferred plant either in your garden or close at hand.
     We have usually raised three species (and I must add that Miriam pretty much does this without a whole lot of help from me), Giant Swallowtail (Papilio cresphontes), Black Swallowtail (Papilio polyxenes) and Monarch (Danaus plexippus).
     The swallowtails are known to seek out Rue (Ruta graveolens) to lay their eggs, so we have it growing in our backyard. At the appropriate time just keep an eye on the plant and you will not fail to notice the females depositing eggs. For Monarchs, a species of milkweed (Asclepias spp.) is necessary and we have Swamp Milkweed (Asclepias incarnata) and Butterfly Milkweed (Asclepias tuberosa), both containing a poisonous, bitter-tasting chemical which remains in the tissue of the adult butterflies and gives Monarchs immunity from predators. Dill (Anethum graveolens) is also accepted by swallowtails but milkweeds are essential for Monarchs.
     Bring stems of the plant indoors with lots of leaves for the caterpillars to munch on when they hatch, keeping them green and fresh by standing them in water, and then watch the process unfold. When the caterpillars first emerge from the eggs you will be astounded at how tiny they are, yet you will be even more amazed at their rate of growth and the sheer volume of frass that accumulates at the bottom of the cage. You can't believe how much poop one little caterpillar can produce! We line the bottom of the cage with newspaper and change it regularly, and provide new food constantly.
     If you are fortunate and are able to catch the moment when the caterpillar forms a chrysalis, or the butterfly emerges from the chrysalis, you will be moved by the experience in a way that little else in life has moved you. It all takes place very quickly, however, so you have to keep checking!
     When the butterfly emerges from the cocoon it hangs for a while inflating its wings and letting them dry; after which it is good to go on its journey as an adult butterfly.

     We are finished with swallowtails for this year but have several Monarch caterpillars at various stages of development in the house now, so we have much pleasure and excitement to look forward to.

Other Odds and Ends

     After four months of not getting together our Tuesday Rambles with David resumed, and we were careful to practice socially-distanced birding.


     From left to right above - John Pries, Carol Gorenc, Jim Huffman, Judy Wyatt, David Gascoigne, Franc Gorenc, Mary Voisin.

     Eastern Kingbirds (Tyrannus tyrannus) appear to have had a very successful breeding season and we have seen several newly-fledged families of these delightful flycatchers.


     The local creeks, swamps and wetlands harbour good populations of Midland Painted Turtles (Chrysemys picta marginata) which can often be seen sunning themselves on a convenient log.


         The young Ospreys (Pandion haliaetus) at RiverSong have now left the nest and this lone adult was perhaps more than a tad relieved to be free of parental duties.


     We have had a decent amount of rain of late, much needed and very welcomed by various species that gather in low spots in fields flooded by rainfall. This Killdeer (Charadrius vociferus) was taking full advantage of the conditions.


     Spotted Sandpiper (Actitis macularius) is quite common around the shoreline of lakes, ponds, rivers and streams, but it was unusual to find one just taking a rest.


     We continue to get out every day and we are almost giddy with the full flush of nature at this time of the year. Life like this really is the way life was intended to be.

  1. Thank you David, that is really interesting. I have just looked on the internet and see that cages are available, so next year hopefully I can get myself organised.
    I have watched a dragonfly emerging from the nymph stage which was really mesmerising too.
    It is great news that you have all been able to resume your Tuesday ramble together.

  2. Your appreciation of nature is appreciated. So many people just pass it by and take it for granted. These days, we are not able to get out and about to see what is going on so it is good to read about your discoveries. Not sure I would want to breed butterflies myself, but they really are beautiful to see. Never thought about caterpillar poop before though.

    1. There is lots of nature watching that can be done from a car, Jo. Let me know if ever you feel motivated to do so and I can steer you to several spots. Just this afternoon I was sitting in my car, which effectively acts as a blind, watching a recently fledged Eastern Bluebird being fed by two devoted parents.

  4. Buenas noches, dear friend how are you! i was amazed and really loved the process of raising butterflies. Their transformation is so amazing ... you are the magicians of Nature. Make of this world a better place. These fragile and delicate beings adorn the planet and the air. That beauty. They are fascinating to see them fluttering in the gardens when spring begins and they are very important for biodiversity, they are the paradise of the Earth, they are peace ♥ ️🤗🍃🌸🍃🌼🍃🌺

    I'm glad to know that you can resume your walks, that's great!

    Changing the subject, i want to tell you that Blogger changed and it is a nuisance for me. I was never able to correctly insert the images. Sorry :(

    Adios, un gran abrazo hasta los bosques maravillosos de Ontario, Canada

  6. David - thanks for the thorough guidance on raising butterflies - it is something I would like to try sometime. Glad you have been able to resume your birding group and that it continues to bring you such joy. Lovely photos!

  7. I have several times watched a monarch hatch from a chrysalis and it never fails to leave me filled with awe at how perfect and how beautiful nature is.

  8. It is always interesting to go out in the neverending process of nature. It’s wonderful you can do that again with a group of friends.

  9. Good morning David. Thanks for sharing all about raising butterflies, you are doing a great job there. Glad you got out for a group hike again, and were able to experience things together and still keep apart. You are all sensible, not like some idiots here! Love the sandpiper, so pretty, and the turtle is gorgeous. Have a wonderful day, take care, hugs, Valerie

  10. Hello David,

    It's very interesting to read about. The butterflies are so beautiful, and the Black Swallowtail is my favorite. Here it's very little butterflies this summer, but I hope they will come soon. Have a great weekend!

  12. Hello,

    Thanks for sharing the Butterfly information. I do not see the Giant Swallowtail here, they are a rare sight here. They are all beautiful. It is great you could get your group of birders together for a walk. Great bird sightings. The last shot of the Spotted Sandpiper is my favorite, love the Osprey too. Happy Birding! Take care, have a great day!

  13. Gracias por tus explicaciones amigo David sobre las mariposas, nunca lo he intentado pro igual me hago el animo, es fascinante poder ver todo el proceso.
    Un fuerte abrazo querido amigo y compadre David.

  14. Hi David.

    Nice to grow the butterflies indoors.
    Beautiful the other animals.

    Greetings from Patricia.

  15. Hi David – what sort of room do you keep the cages in? … different cages for each species? About how long while each species hatches? Do you need to keep the temperature relatively constant … with fresh air around?

    So glad you were able to get together and ramble again … seeing the avian and wild life … turtles, ospreys – majestic birds – spotted sandpiper … really relaxing on its stone.

    So pleased you are sort of back to the way life was intended to be … particularly in the Miriam and David household. Take care - Hilary

    1. It is really straightforward, Hilary. We keep the cages (see picture number two above) in the kitchen. There they are very fortunate actually. Don't forget that outside a whole host of predators are intent on eating them, and they have to deal with all the vagaries of the weather - heat, rain, wind. Once we bring the eggs inside there is 100% success rate. And their food supply never runs out since we bring them fresh supplies every day. These are pampered lepidopterans!

      Delete
    2. Thanks for that ... I had decided you had an annexe porch on the house or something - didn't expect the kitchen to be happily breeding the beloved lepidopterans - but am happy you are successfully letting them live in the world. Thanks for the answer! Take care - H

  16. It was thrilling for me last year to witness Monarchs emerging.

    ReplyDelete
  17. Now I'm getting seriously tempted, David. However, while watching dragonflies ovipositing recently, I started hatching a plan - now that I have a mini-pond. Rather than return to rearing butterflies and moths, I might just chance my luck with dragonflies? Thereagain, waiting for a couple of years or more for adults to emerge might just push that patience you mentioned recently!

    I'm delighted to hear of the resumption of 'Rambles with David'

    Best wishes to you and Miriam - - - Richard

  18. It must be exciting to watch the life cycle of the butterflies.

    Turtles fascinate me. I’ve never lived where they live too. I am envious of your turtle sightings!

    ReplyDelete
  19. The rain was so welcome, wasn't it?
    I'm really against raising the butterflies indoors. It's lovely to watch, but the research on monarchs, and tagging and tracing them, seems to show that they need to be outdoors in the light and under the stars to form properly.

    ReplyDelete
    Replies
    1. I have seen research that indicates rearing Monarchs indoors may interfere with their ability to navigate, but as far as I can recall, I have not learned that they do not form properly. I will check this point. As for the other species, I know of no ill effects and both species of Swallowtail that we raise are multi-generational in Ontario and live for mere days upon release. Are you against raising all butterflies indoors. Would you be in favour of closing down all butterfly conservatories and eliminating the butterflies in rain forest exhibits in zoos?

  20. Hello David, Wonderful information of the rearing of the butterflies done by Miriam. Much better to look at than watching television ;) Rain is so welcome after long absence. We now have a heath wave and do hope at the end to be dancing in the rain.
    Good to read you are again going out with the bird watchers groop with Covid 19 distance.
    Happy to read the Ospreys have left the nest. Not long now before they start their migration South.
    All the best and stay safe,
    Regards,
    Roos

  21. You're a pro with butterflies David. Love your photos of them and one of Ospreys. It seems to be ready to catch food.

  22. I love your socially distanced birders photo! Someday I hope this is all just a memory of a very interesting time.

  23. Glad to see that once again you can enjoy nature with your friends. Love the turtle, we don't see them here, at least I don't. Have a great day!

  24. Quite impressive. I think I would be watching them every minute!

  25. The butterflies fascinate me. This is so special, so remarkable. You are the butterfly whisperers!

    Glad to see the ramble is back on and what a nice looking, well spaced out group. I see you were rewarded by lovely sightings!

  26. I raised butterflies in the 3rd grade. Not because I wanted to, but because it was a school activity. :)

  27. We used to do this when I was at school but I certainly have never tried it myself. Interesting thoughts. You photos are superb. Keep safe and enjoy the rest of the week. Diane

  28. Interesting pictures as always. Raising butterflies indoors seems to be having a "moment." I've noted it popularity with many people. I have a friend nearby who is heavily into raising Monarchs and has done for a few years now. I don't think I'm up for such a commitment, but I admire those who do.

  29. Hello and good afternoon from Norway.A really good post how to breed those big butterflies.Here we can not do so it is to cold everywhere all year mostly(Still we have a heatwave now in Bergen)

  32. I so enjoy reading about people's experiences with butterfly-raising. One of the refuges I visit has an educational center where they work with them, and involve children who visit in the process in various ways. I'm glad your group is able to begin going out now, too. The photo of the sandpaper on the rock is marvelous: there's something about a bird at rest that's always appealed to me.

    1. The irony is about the group that after four months of birding alone or with Miriam, I am not so sure that I don't prefer it that way. We have only had a couple of outings so I'll give it time, but initially I was not overwhelmed by getting back together again.

  33. What a beauty of butterflies... Nice shots of Osprey.. Happy weekend David

  34. Wonderful to see and read David.
    I myself have already seen the caterpillar of the Orange tip pupate and took pictures.
    Overwinter these on a twig in the shed and take pictures again in the spring when it was just out. Beautiful process to follow.
    You have beautiful butterflies in the picture.

  35. Wow. So interesting. I learn so much. Thank you.

  36. Hi David,
    Raising butterflies is a laborious but intersting hobby. I can imagine the both of you like it very much. You have chosen some beautiful species what makes it even more attractive.
    Making strolls again in the nature is a pleasure, especially in the present corona times. With us it is pretty hot and dry, which forces you to wander in the nature at very early hours (a thing I really like to do).

    Love your header and the Giant Swallowtale is stunning!!

  40. ...we visited a nature center yesterday and saw more butterflies than all this year combined.

  41. Thank you for coming by my blog, and for leaving a lovely comment. I appreciate your point of view, on picture taking.

    Have read before, about this wonderful process, you describe here. A lady blogger, did this also. So I am a tiny bit familiar, with it. But not really familiar, of course.

    Personally, I would be too worried, I would harm them, in some way. Because I am a "Worry-Wart"!!!! ~sigh~ But am very happy, that sensible people, are willing to do it.

    A lovely close up and personal view of Nature. Which is rare, in this *Advanced World,* in which we live. Sadly.... Very sadly....
