Edmunds, R.: Parna apicalis (Brischke, 1888) and Hinatara recta (G. C. Thomson, 1871) (Symphyta: TEnthredinidae) in Hungary
18 Natura Somogyiensis Szigethegység (Mimtii Apuseni) (Scobiola-Palade 1981) and Trepcza k. Sanoka (Beiger 1982). Altenhofer, E., & Pschorn-Walcher (1998) described the leaf mines and larvae of Hinatara species. Material and methods On the last day of our city break in Budapest (21.iv.2016) my wife and I visited Margaret Island, where I found a leaf mine of Parna apicalis around 47°31'45.30"N and 19°3'2.52"E and later the Gellért Monument approximately 47°29' 19.86"N and 19° 2'49.89"E, where there was a leaf mine of Hinatara recta. Results Parna apicalis (Brischke, 1888) Our boat trip along the Danube allowed us a break on Margaret Island and we walked around the Northern end of the island. It was here that I saw the mine of Parna apicalis on Tilia sp., this is a mine I am familiar with since its discovery in the UK (Edmunds et al. 2007). On Tilia there are two sawfly leaf miners, which are separable on the basis of phenology and morphology - Parna apicalis (Brischke, 1888) and Parna tenella (Klug, 1816). Both are univoltine but P. apicalis forms leaf mines from late April to early June, whereas P. tenella mines from late May until early August. The leaf mines of P. apicalis are smaller and found as semicircular blotch mines at the leaf edge, whereas those of P. tenella are much larger and cause the leaf to roll upwards. There may be several mines in a leaf in this latter species, whereas in P. apicalis there is usually only one. P. tenella also tends to be found in suckers at the base of its food plant, whereas P. apicalis is found in the leaf canopy of the tree (Fig. 1). Halstead (2009), details differences in the frass of the two species with P. apicalis having small frass pellets 0.5mm long. Those of P. tenella are much larger at up to 2mm in length. Both species feed on a number of Tilia species. In Germany, Liston (2006), found P apicalis mines on T. cordata, T. platyphyllos, T. petiolaris, T. mongolica, T. x moltkei and T. x euchlora. Halstead (2009), lists the host plants for this species in the UK as T. americana, T. cordata, T. ‘Emerald Spire’, T. europaea, T. heterophylla, T. mexicana, T. mongolica, T. orbicularis, T. platyphyllos and T. tormentosa. Halstead (2004) lists the Tilia species mined by P. tenella in the UK as T. americana, T. chenmoui, T. chinensis, T. chingiana, T. cordata, T. x europaea, T. heterophylla, T. mexicana, T. ‘Moltkei’, T. mongolica, T. oliveri and T. platyphyllos. The larvae of both species appear very similar (Fig. 2) but the adults can be separated on morphology. The adults of P. apicalis appear all to be female (Altenhofer 1980) and so the development of this species is parthenogenetically.
