 o
Centauria as Host for AL

Posted by Leafhead 4b WI (johngern@gmail.com) on

Has anyone heard of American Ladies using Centauria as a host plant? I've always thought the caterpillars were limited to the Leonapodoides tribe of Asteraceae (Pussytoes, Everlasting, Edelweiss, Artemisia etc). This morning I found the tell tale nest with a cat inside on my Mountain Blues Centauria. He must have ran out of Pussytoes and found a home there. Uff-da!

Never heard of them using it. Keep tabs on it and let us know if it succeeds. I have some everlasting growing near my centaurea.

Must like the tomentose (fuzzy) leaves.

Keep us posted as to how the caterpillar does, John.

I've never heard of that plant being used.

Runmede,
That list sounds more like the Painted Lady's diet. I followed that link and it seemed to lump all the Vanessas (Cynthias) together.
Meanwhile, AL cat #2 has found its way to my Mountain Blues Centauria and has gone thru half a leaf! I think I'm witnessing a species jumping in progress...

RE: Centauria as Host for AL

From Dr. James Scott's CD-ROM, "The Butterflies of North America, "A Natural History and Field Guide." I recommend this for easy access to information on butterflies.

Centaurea solstitialis, nigra, is listed for the Painted Lady. The ladies do share some common host plants.

"Vanessa virginiensis American Painted Lady
Hostplants herb Compositae: Gnaphalium palustre, obtusifolium, bicolor, purpureum, Antennaria parvifolia, plantaginifolia, neodioica, Anaphalis margaritacea, Artemisia douglasiana, absinthium (?), stelleriana (?), ludoviciana, Arctium lappa, Cirsium arvense, Carduus, Onopordum acanthium, Silybum marianum, Helianthus, Vernonia, Senecio maritima (?), cineraria; Boraginaceae: Echium vulgare, Myosotis; Leguminosae: Lupinus; Malvaceae: Althaea rosea, Malva; Urticaceae: Urtica; Balsaminaceae: Impatiens capensis (?); Scrophulariaceae: Antirrhinum. Prefers the Compositae tribe Inuleae (the first three genera)."

Obviously prefers Compositae, esp. Cirsium. Sometimes a pest on Iowa soybeans (Glycine). One larva eats about 234 square cm of soybean leaves in its lifetime, all but 7 square cm in the last two larval stages (F. Poston)."


 o
Inuleae Tribe

Scott said "Prefers the Compositae tribe Inuleae (the first three genera)."

That little caterpillar knows what it is doing.

Centaurea is in the Family: Asteraceae.

"Inuleae is a tribe of flowering plants in the subfamily Asteroideae.

Asteroideae is a subfamily of the plant family Asteraceae. It contains about 70% of the species of the family.

It is made of several tribes including Astereae, Calenduleae, Eupatorieae, Gnaphalieae, Heliantheae, Senecioneae and Tageteae.

Asteraceae or Compositae (commonly referred to as the aster, daisy, composite, or sunflower family) is the name of an exceedingly large and widespread family of flowering plants (Angiospermae). The group has more than 23,000 currently accepted species, spread across 1,620 genera (list) and 12 subfamilies."
