Scrobipalpa obsoletella (Fischler von Röslerstamm, 1841)
The larve bores in the pith of part the stem, that takes a fusiform shape. The frass is ejected through a hole in the stem, always at the base of the leaf or side branch. According to Hering (1957a) the larva makes excursions into the leaves, making irregular blotch hmines. However, according to Jansen this is only rarely the case, and Bland ao (2002a) do not mention this behaviour altogether.
In Hering’s time the difference between obsoletella and S. nitentella was incompletely known. Both species were even synonymized in 1961 by Sattler, and only in 1988 this synonymy was reversed by Povolný. Conceivably Hering described the biology of a mix of both species.
Larvae in June – July and again from September; hibernation as larva (Jansen, 1999a).
