Digger wasps are cosmopolitan predators that can sting and paralyze prey insects. In preparation for egg laying they construct a protected "nest" (some species dig nests in the ground, while others use pre-existing holes) and then stock it with captured insects. Typically the prey are left alive, but paralyzed by wasp toxins. The wasps lay their eggs in the provisioned nest. When the wasp larvae hatch, they feed on the paralyzed insects. A well-known species of digger wasp is the great golden digger (Sphex ichneumoneus) which is found in North America. The developing wasps spend the winter in their nest. When the new generation of adults emerge, they contain the genetically-programmed behaviors that are required to carry out another season of nest building. During the summer, a female might build as many as half a dozen nests, each with several compartments for her eggs. The building and provisioning of the nests takes place in a stereotypical, step-by-step fashion.
Asclepia L., the milkweed,is a herbaceous that contains over 140 known species and is classified as part of the dogbane family. Milkweeds are an important nectar source for bees and other nectar seeking insects, and a larval food source for monarch butterflies and their relatives, as well as a variety of other herbivorous insects specialized to feed on the plants despite their chemical defenses. Milkweed is named for its milky juice and some species are known to be toxic. Strangely enough though Carolus Linnaeus named the genus after Asclepius, the Greek god of healing, because of the many folk-medicinal uses for the milkweed plants.
As I read this information I thought "this reminds me so much of Euphorbia" and sure enough when I looked at the botanical "class"(Magnoliopsida) and "division" they were same....a bit like having the same great grandparents but developing your own characteristics.
I'm not exactly sure which form of Ascepia W.o.t.V had but this is a photo of one that truly proves what a nectar bar it is.Speaking of insects....I took a photo of this bee in our garden yesterday afternoon....I'm not sure if it is trying to build a nest, the hole is really small and in the concrete post of the fence....I think it more likely it was sheltering from the weather....................and with black skies like this looming I'm not surprised!
I did say at the beginning of June that I'd take regular photos of the garden from one particular angle just to see how it changes......
Despite the unseasonal weather everything is still growing and I hear from the weatherman that things may be set to improve!!
