Dahlica(bagworm moth)
Kearfottia

Naryciinae is a of bagworm moths (Psychidae) characterized by monandrous females that mate only once. Females are immobile and wingless, while males are short-lived, non-feeding, and capable of multiple copulations. Several exhibit parthenogenetic , including *Dahlica fennicella* and *D. triquetrella*. The subfamily serves as for a diverse complex in northern European .

Distribution

Central Finland (documented); broader distribution within Psychidae range implied but not specifically established for Naryciinae.

Life Cycle

Larval stage is the primary feeding and growth phase; studies indicate larval stage is vulnerable to attack by koinobiont and idiobiont . Developmental timing differs between sexes, potentially causing reproductive asynchrony.

Behavior

Females are monandrous (mate once) and immobile. Males are short-lived, do not feed, and are capable of multiple copulations. Unfertilized females are capable of re-mating. has evolved repeatedly in this group.

Ecological Role

for at least nine ; rate of 25.7% documented in sampled Central Finnish . Parasitoid includes both koinobionts (Diadegma incompletum, Macrus parvulus, Trachyarus borealis, T. solyanikovi, T. fuscipes, T. brevipennis, Meteorus affinis) and idiobionts (Orthizema flavicorne, Gelis fuscicornis).

Misconceptions

Sperm limitation from male mating history was hypothesized as a driver of evolution in Psychidae, but empirical study found that male mating history did not cause strong sperm limitation in Naryciinae despite traits suggesting otherwise.

More Details

Male mating effects on female fitness

In *Siederia listerella*, females produced 30% fewer offspring when mating with previously mated males. In *Dahlica lichenella*, female reproductive success was higher when males were older and had fewer total lifetime copulations.

Sex ratios and male limitation

Only a fraction of 53 investigated natural showed female-skewed sex ratios; differences in development time between sexes may create reproductive asynchrony rather than absolute male limitation.

Cryptic parasitoid diversity

Molecular analysis revealed cryptic in *Macrus parvulus* associated with sexual versus parthenogenetic , and that *Trachyarus brevipennis* and some *T. fuscipes* are of one species.
