4B5C4772FFC0DA38FE33FDECFED5FE16.taxon	description	Description of the last feeding instar larva. Body length 10 – 12 mm. Head black, in lower part yellowish; whole head covered with scattered fine homogeneous pubescence; clypeus with six setae, labrum with four setae; mandibles with two setae, stipes and palpifer with two setae; second segment of maxillary palps with one small seta; praementum with two setae, second segment of labial palp with one short seta; body in upper part grey-yellowish, in lower part paler; cuticle granulose, spiracles black; first annulus of prothorax with a pair of large dorsal lobes with short cylindrical setae, third annulus of prothorax and first and third annulus of mesothorax with a pair of short wart-like projections with several short cylindrical setae; trochanter as long as femur, with scattered long hair-like setae, tibia as long as tarsus with three hair-like setae, third abdominal segment with seven annulets; second and fourth annulets with a pair of short dorsal cylindrical setae, first postspiracular lobe with one, second postspiracular lobe with two short cylindrical setae, prominent subspiracular and suprapedal lobes with short cylindrical setae, ninth abdominal segment with transverse, bilobed ridge with short scattered cylindrical setae, suranal lobe with short hair-like setae posteriorly; basal interior parts of prolegs with several long hair-like setae. Notes on identification. The larvae of Birka annulitarsis differ from the similar larvae of B. cinereipes in smooth abdominal segments and bilobed transverse ridge on the ninth abdominal segment. Bionomics. Habitat: mesic meadows, oak-hornbeam and thermophilous oak forests from colline to submontane zone. Polyvoltine. Flight period from mid April to the beginning of September. Larvae were collected in August and September on leaves of Pulmonaria angustifolia in the flowery meadows of Bílé Karpaty Protected Landscape Area in southern Moravia, Czech Republic. They can be found by day, tightly attached with body outstretched on the base of upper surface of leaf blade of the food plant. The larvae are easily detected because of the sceletonized holes on the leaves. Mature larvae build a firm cocoon in soil, where they hibernate in praepupal stage.	en	Macek, Jan (2013): Descriptions of larvae of Birka annulitarsis and B. cinereipes (Hymenoptera: Symphyta: Tenthredinidae).

4B5C4772FFC0DA38FE33FDECFED5FE16.taxon	discussion	Discussion. ZIRNGIEBL (1954) noted Rubus sp. as host plant without any more details on the developmental stages relating to this plant. For that reason LISTON (1995) and TAEGER et al. (1998) mentioned Rubus as a problematic food plant and indicated it with a question mark. MACEK (2009) first recorded Pulmonaria sp. from Bílé Karpaty Mts. as a proved larval foodplant based on the collection and rearing of larvae. The food plant is here specified as Pulmonaria angustifolia L. Besides, adults of this species were also swept in various parts of Bohemia in deciduous forests with rich growth of Pulmonaria officinalis, which might be another larval foodplant.	en	Macek, Jan (2013): Descriptions of larvae of Birka annulitarsis and B. cinereipes (Hymenoptera: Symphyta: Tenthredinidae).

4B5C4772FFC2DA3FFE14FE0FFE51FE31.taxon	description	Redescription of the last feeding instar larva. Body length 9 – 12 mm. Head black, clypeus and labrum brown, whole head covered with scattered fine homogeneous pubescence; clypeus with six setae, labrum with four setae; mandibles with two setae, stipes and palpifer with two setae; second segment of maxillary palps with one small seta; praementum with two setae, second segment of labial palp with one short seta; body in upper part black grey, in lower part yellowish grey; cuticle granulose, spiracles black; prothorax with a pair of enlarged dorsal and subspiracular lobes and wart-like suprapedal prominence; mesothorax with a pair of short wart-like dorsal projections and wart-like lateral projection; trochanter as long as femur covered with scattered hair-like setae, tibia as long as tarsus, covered with several scattered setae; body setae, excluding suranal and subanal lobes very short, cylindrical; third abdominal segment with seven annulets; annulets two and four with a pair of prominent wart-like dorsal protuberances with two setae; second annulet with two, fourth annulet with one, and third annulet in lower part with one, pale swellings with one or two setae; first postspiracular lobe with one, second postspiracular lobe with two or three setae; prominent subspiracular and suprapedal lobes with six to eight setae; ninth abdominal segment with transverse ridge with four lobes with two setae; suranal lobe with dense long hair-like setae on posterior half erected from black tiny conical warts; basal interior parts of prolegs with scattered conical and hair-like setae. Notes on identification. The larvae of Birka cinereipes differ from the similar larvae of B. annulitarsis in the second and fourth annulet of the abdominal segments with wart-like protuberances and quadrilobed transverse ridge on the ninth abdominal segment. Bionomics. Habitat: mesic and humid meadows, shore vegetation alongside waterpools, brooks and rivers from planar to montane zone. Polyvoltine, flight period from the end of April to the beginning of September. Host plants: Myosotis palustris, M. arvensis (LORENZ & KRAUS 1957). I collected the larvae abundantly on Myosotis palustris in September beside the shore of the pool in Karlštejn NNR and in July in a humid meadow in Částrovické rybníky NR. The larvae rest oustretched on the lower side of the leaf and are detectable by the characteristic sceletonized holes. The larva is inactive, falling down to the herb litter if disturbed and resting here with outstretched body for a long time. The mature larvae burrow into the soil, forming a firm cocoon for hibernation in the prepupal stage.	en	Macek, Jan (2013): Descriptions of larvae of Birka annulitarsis and B. cinereipes (Hymenoptera: Symphyta: Tenthredinidae).

4B5C4772FFC2DA3FFE14FE0FFE51FE31.taxon	discussion	Discussion. The larva was first described by LORENZ & KRAUS (1957) and supplemented with some other additional characters by VIKBERG & NUORTEVA (1997). However there are some discrepancies in description of the third abdominal segment between these authors, caused by their different conventions for numbering the annulets: annulet 3 in the latter publication is annulet 2 in the former. The redescription provided here is more easily comparable with the description of B. annulitarsis.	en	Macek, Jan (2013): Descriptions of larvae of Birka annulitarsis and B. cinereipes (Hymenoptera: Symphyta: Tenthredinidae).
