The Monarch butterfly population is declining due to decreasing habitat in Mexico and the USA. You can help the Monarch planting milkweed in yards, gardens and open areas in the Monarch migration paths. There are vacant lands where seeds of milkweeds and wild flowers can be planted, this includes roadsides and power line right-of-ways. This year the monarch started their migration north, but the climate prevented milkweed plants from maturing enough to provide leaves for female butterflies to lay eggs and to feed the newly hatched caterpillars. Starting milkweed plants inside, then replanting them outside for the migrating butterflies to use will help sustain the Monarch butterfly population. Harvesting Milkweed seeds in the fall will provide seeds to plant in the spring. Your area may have seen a decline in Monarch butterflies. Monarch eggs, caterpillars and chrysalises can be purchased online or from local butterfly farms.

  • 7. The next 20 slides illustrate the Monarch Life Cycle. All the Photosand technical writings were created by Sid and posted on Flickr.Sid Mosdell, contributor to FlickrGo see Sid’s genius on Flickr.leave glowing commentshttp://www.flickr.com/photos/sidm/sets/72157624547070910/Sid’s Bio - Im 76, married, and have livedwith my wife in Picton (a small seaside townof about 4000 in the South Island) sinceretiring from the rat-race in Auckland(New Zealands biggest city) 11 years ago.Ive been a fairly keen amateur photographersince my teen years. My switch from filmto digital occurred about 8 years ago andI discovered on-line photo sharing via Flickrabout 5 years ago. My two current camerasare a Micro Four Thirds format PanasonicLumix and a Panasonic Lumix FZ150.
  • 8. Monarch ButterflyFemale Monarch butterfly deposits an egg onto the underside of amilkweed (swan plant) leaf. The butterfly usually lays its eggs on leaves but occasionally they are found on milkweed stems. Lastyear I posted three photos of a monarch caterpillars transition to a chrysalis. Unfortunately at that time I never did get around to expanding the series any further. Now that were well into a wetmid-winter here in New Zealand Ive had some time to sit indoors and sift through my Monarch photos. This is the first of twenty images depicting stages in a Monarchs life cycle.
  • 9. Monarch Butterfly EggA Monarch butterfly egg on the stem of a Swan Plant milkweed.This egg (about the size of an aphid) took eight days to hatch.
  • 10. Monarch Butterfly CaterpillarThis tiny (1/6” long) eating machine has very recently hatched. Itsfirst meal was to nibble at the shell of its egg and now it is tackling the leaf of a Swan Plant. It is still too small to penetrate through the leaf but within a day it will start leaving tell-tale gaps in themilkweeds leaves. When a caterpillar outgrows its skin it molts, or sloughs off, its old skin. The stage between molts is an instar. Monarch caterpillars have five instars.
  • 11. Monarch Butterfly Caterpillar Monarch Caterpillar— Second Instar.The caterpillar is now three days old and 7/16” long.
  • 12. Monarch Butterfly CaterpillarThis Monarch caterpillar, now into its fifth instar and about 2” long, has just shed its skin. The skin, which can be seen lying on the leaf behind it, is usually eaten by the caterpillar shortly after molting. This caterpillars next molt will result in a chrysalis.
  • 13. Monarch Butterfly Caterpillar Monarch caterpillar on a Swan Plant milkweed, fifth instar, about 2 3/16” long and close to pupation. It is now about three weeks old. however this time-span depends very much on temperature and can vary considerably. When they are ready to pupate thecaterpillars tend to wander around, sometimes relatively far afield, presumably in search of a suitable chrysalis-friendly site.
  • 14. Monarch Butterfly Caterpillar The Monarch caterpillar readies itself for pupation. It has spun acushion of silk by which it attaches itself to a suitable surface and hangs head-down in a J-shape.
  • 15. Monarch Butterfly CaterpillarAfter being suspended from its silk cushion for about 18 hours theMonarch caterpillar starts to straighten out. This is the prelude to shedding its larval skin for the last time. Look carefully at the image and you will see the skin just starting to split behind its head before being pushed upward.
  • 16. Monarch Butterfly Pupa By wriggling, as well as rhythmically contracting and expanding, theMonarch larva (caterpillar) pushes its skin upwards. The jade green pupa (chrysalis), at this stage still very soft, can now clearly be seen.
  • 17. Monarch Butterfly PupaThe pupa now starts wriggling and gyrating energetically to finally dislodge its skin. This Monarch took 12 minutes to complete the molting process. .
  • 18. Monarch Butterfly Pupa This beautiful new jade-colored Monarch pupa is still soft and wrinkled. Some areas of the adult butterfly-to-be are already apparent. Within the next 1 to 2 hours its casing will harden,smooth out and assume the familiar shape of a mature chrysalis.
  • 19. Monarch Butterfly ChrysalisThe Monarch chrysalis, now smooth with a hard wax-like casing, is a lovely jade green color with gold spots, hence the name chrysalis, from the Greek word chrysos for gold.
  • 20. Monarch Butterfly Chrysalis To ButterflyShortly before the butterfly is due to emerge the Monarch chrysalis darkens significantly and the orange color of the wings can be clearly seen through its casing.
  • 21. Monarch Butterfly Chrysalis To ButterflyThe transparent casing of the chrysalis has now cracked open and the Monarch butterfly is emerging, clinging with its legs to thecasing to protect itself from falling to the ground. The pupal stage of the Monarch is usually from 10 to 14 days long. However the time-frame is dependent on the season and the ambient temperature. This pupal stage lasted for 23 days.
  • 22. Monarch Butterfly Chrysalis To ButterflyStill clinging to the empty shell the damp Monarch butterfly pumps fluid (hemolymph) from its distended body into its wings. In thisphoto the wings are slowly expanding but are still quite stubby and wrinkled.
  • 23. Monarch ButterflyThe newly emerged adult Monarch butterfly still retains a firm grip on its empty chrysalis shell.
  • 24. Monarch Butterfly Seven minutes have elapsed since this adult Monarch butterflyemerged from its chrysalis. The butterflys wings have expanded but have yet to harden properly.
  • 25. Monarch ButterflyA newly emerged adult Monarch butterfly, its wings fully expanded and by now probably fully hardened and functional, slowly makesits way upwards towards a high point on the Swan Plant milkweed.
  • 26. Monarch Butterfly About two hours after emerging from its chrysalis this beautiful adult Monarch spreads its wings in preparation for its first flight. The butterfly in this photo is a male. Males have a clearly visible black spot on each hind wing from which pheromones arereleased. The next image in this series, also of a recently emerged adult Monarch, is a comparative photo of a female.
  • 27. Monarch ButterflyFreshly emerged from her chrysalis this female Monarch will soon make her first flight. The webbing on a females wings is thickerthan the webbing on a males wings and females do not have the black spots on the hind wings that are a characteristic of males (see previous photo in this set).
