Blue Jay (Cyanocitta cristata). Beautiful and exceptionally intelligent birds. They’re mimics. Included in their repertoire, are the calls of many hawks, particularly the Red-shouldered Hawk, and some owls. Predators that Blue Jays will avoid.
Males and females are alike except that males are a bit larger. They are monogamous, staying together for life. Both participate in nest building and raising their young, and have strong family bonds.
At your backyard feeder Blue Jays will eat most anything that you’ll put out for all the birds with the exception of Nyjer seed. I haven’t had my feeders out since late spring and plan to put them out tomorrow. I’m looking forward to seeing the Blue Jays that I’ve been hearing in the woods.
Red-spotted Purple (Limenitis arthemis). With a wingspan of three to three and a half inches. Looking quite handsome with its iridescent blue with tiny orange spots on the dorsal (top) side of its wings. At this point I have to mention that this butterfly is on Butterfly Bush. BUT this plant is NOT in any of my gardens. As an invasive it will take over places where native plants could be growing and benefitting our natural world.
It’s the great impersonator. The Red-spotted Purple butterfly mimics the Pipevine Swallowtail butterfly. And not stopping at that, the larvae quite convincingly mimics bird droppings.
Preferred host plants of the Red-spotted Purple are a wide variety of trees and shrubs including birches, aspens, wild cherries and many species of the willow family. The adults feed on an occasional flower, as well as damp soil and puddles, carrion, dung and rotting fruit. One of those butterflies.
My first sighting this season was yesterday. The state insect of Virginia, the Eastern Tiger Swallowtail Butterfly (Papilio glaucus). Native to eastern North America. The butterfly I saw yesterday had just emerged from its chrysalis. Brand new.
This is what a chrysalis looks like. Though NOT an Eastern Tiger Swallowtail chrysalis, it looks to a large extent like one. One major difference would be more rich brown and less bright yellow. The shape is basically the same. This is a Pipevine Swallowtail (Battus philenor) chrysalis.
In the autumn an Eastern Tiger Swallowtail caterpillar will form itself into a chrysalis. NOT a cocoon but a chrysalis. Cocoons are used by moths. Chrysalises are used by butterflies. In ten to twenty days or over the winter the caterpillar makes incredible changes. As if by magic it will become a butterfly — to live just six to fourteen days.
Mainly males, after emerging, often will gather at puddles to take in sodium and minerals which tend to be lacking in the adult’s diet and are necessities for reproduction and flight. This is called “puddling.”
Speaking of reproduction, Eastern Tiger Swallowtails generally have two broods each year. Females lay their eggs on such trees as Tulip Poplar (Liriodendron tulipifera) and Wild Black Cherry (Prunus serotina). Those eggs will hatch in four to ten days as caterpillars. The earliest stage of the caterpillar looks just like bird droppings. The mature caterpillar is green, with eye spots, and a pale “neck ring.” Further to the front is a little purply-pink head.
Although most females look nearly like males, mostly yellow and black, there is a black form of the female Eastern Tiger Swallowtail. This is a method of protection. The black form is a mimic of the Pipevine Swallowtail (Battus philenor) which has a disagreeable taste. Predators have learned to avoid both the Pipevine Swallowtail and the Eastern Tiger Swallowtail’s black form. The portion of females with this coloring is more common in areas where there are more Pipevine Swallowtails.
The caterpillar becomes a chrysalis which becomes a dazzling butterfly. And so it goes. On and on.
