I’ve been admiring some of the Common Milkweed plants that
have put on luxuriant growth despite the super dry conditions. This one has topped out at about seven feet.
Most plants are carrying six or eight seed pods. Tendrils on the surface of the Common
Milkweed seed pod present an alien appearance.
It looks like it’ll be a bumper year for Milkweed
seeds. All of the pods are large and
full. It won’t be long before the seam
separates to release the ripe seeds.
Monarch butterflies are around loading the plants down with
eggs. I watched this female lay 17 eggs
on a clump of three milkweed plants.
It may be warm now, but this egg is in a race to produce a
mature butterfly before cold weather arrives.
Monarchs will not survive an Ohio
winter. In order to survive, the mature
butterfly will have to emerge and make its long migratory journey to the south.
The Monarch is not the only insect depositing its eggs on
the Milkweed leaves. These orange gems
were left by a female Milkweed Bug.
Here’s the likely source of those eggs. This is an adult Small Milkweed Bug, a
species that specializes on eating milkweed seeds that are still held within
the pod.
The nymphs form colonies on the milkweed plants. They are most likely to be found congregating
on the seed pods where they use long, tube-like mouthparts to probe deep into
the pod to access the hidden seeds.
The nymphs will shed their skins several times before
emerging as an adult. To avoid being
damaged during this vulnerable time of their lives, the little bugs will move
away from the pack and pick a secluded spot in which to shed. After a while, shed skins can be found just
about anywhere on the plant. The variety
of interesting activities occurring on milkweeds makes the cultivation of this
plant a rewarding endeavor.
Interesting that the two species I most commonly assoicate with milkweed, the milkweek bugs and monarch butterflies, both have orange coloration, which appears to be the opposite of camoflauge. Advertising that they won't taste good to predators?
ReplyDeleteHi VB. Milkweeds contain toxins that accumulate in the bodies of insects that feed on the plants. This gives the insects a degree of toxicity that strongly discourages predators. It's thought that the bright coloration makes it easier for predators to identify these insects as being unpalatable.
ReplyDeleteFantastic monarch photos! I am thrilled to hear that there are plenty of monarchs around you laying eggs because I haven't seen very many of them this year.
ReplyDeleteYour macro of the Monarch egg show it to be a beautiful work of nature's art.
ReplyDeleteI just love these up close and personal nature photos!
ReplyDeleteStopping by to let you know that you've been nominated for the Sunshine Award! http://greenbeangal.blogspot.com/2012/08/sunshine-award.html
Thanks Tiffany. The Monarchs have just recently arrived. I don't know if they are just now hatching from an earlier brood or if they are migrants cruising south.
ReplyDeleteHi Pat. The egg certainly shows a lot of fine detail for something so small and transient.
Thanks Melissa.
