Genus Strauzia
Synonyms and other taxonomic changes
Strauzia Robineau-Desvoidy 1830
The taxonomy of this genus needs revision and the species concepts are not very clear, according to Allen Norrbom.
Explanation of Names
Named by Robineau-Desvoidy after M. Straus ("Je le dédie à M. Straus, anatomiste")
12 spp. total, all endemic to our area(1)
Nearctic genus(1)
Adults emerge in May and June in the Northeast.
Larvae mine in stems of Asteraceae and are fairly host specific. Hosts include sunflowers, giant ragweed, Rudbeckia, Smallanthus, and Verbesina. [note from Allen Norrbom]
"The stem mines are not visible externally. [Fall/winter] is a good time to look for pupae if you can still recognize the plants and don't mind splitting the stems now that they are dead. The larvae normally start mining in the upper part of the main stem and mine down to the base or into the root crown, where they pupate. The pupae are yellow or orange and cylindrical ovoid. There can be several to a plant. The adults are usually out in May/June. They tend to be on the upper parts of their growing host plants." [note from Allen Norrbom]
