Tachystola hemisema (Meyrick, 1885)
Ocystola hemisema Meyrick, 1885
Explanation of Names
Addition of this species is tentative. See Remarks below.
Numbers
A single adventive species in our area. It was first collected by Norm Bloomfield and tentatively identified by Jean-François Landry (CNC) in 2013.
Identification
See original description in print references below.
Range
Native to Australia, but has been introduced into southern California (Jean-François Landry, CNC).
Season
BugGuide and BOLD records from May-June and September-October
(2).
Food
Eucalyptus, which has been introduced from Australia (Jean-François Landry, CNC)
Life Cycle
"Its larvae construct small, flattened, elliptical cases of silk between joined dead leaves of Eucalyptus, usually adhering to fallen branches" (Jean-François Landry, CNC; adapted from Common, 1997)
Remarks
The identities of the BOLD specimens are not verified including the one from CA identified by J.-F. Landry. There are several neighboring BINs with similar specimens. We do not know which, if any, of these BINs represent T. hemisema. According to Landry, a T. hemisema identification is reasonable but should be considered tentative. Once the identity of the Australian specimens are verified, Landry will publish his findings.
Landry is looking for additional samples, particularly females, which can be sent to him directly. I have his address for those interested. - Steve Nanz
