11.002 Narycia duplicella (White-speckled Bagworm)
Female fully-developed. ws: m9-12mm f7-10mm; Jun-Jul; common in S.England, more local further N.
Ocelli absent; labial palp 3-segmented; foretibia without spur but with long tuft of dark scales.
Larval case on tree trunks May-Jun.
Key in MBGBI2 is confusing as it relies on determining either that this species has ocelli (which it doesn’t) or a foretibial spur (while the species description states that what looks like a spur in this species is actually a tuft of scales). The key also relies on determining that the antenna is fasciculate rather than ciliate and then describes it as ciliate in the species description!
