Tom. 60 .. 1963 No. 1 ... 2 x Institute of Entomo~ogy, Czechoslovak Academy af Science, Praha HEMEROBIIDtAE (NEUROPTERA) FROM CZECHOSLOVAKIA Hemerobiidae (Neuroptel'a) z Geskoslovenska JIRi ZELENY Received September 14, 1962 Ie uvedeno celkem 30 druhii celedl Hemerobiidae nalezanych u nas s poznamkami a jejich rozslreni ve svete a s udaji 0 bionomii. Ie pripojen obrazkovy klfi.! k urceni druhii nalezenych v GSSR. Je popsan novy druh Sympherobius klapaleki sp. n. a jsou uvedeny tri druhynove pro faunu CSSR: Hemerobius perelegans , Boriomyia raua a B. killingtoni. Pro Slovensko jsou nove druhy: Boriomyia killingtoni, B. raua, Hemerobius perelegans, H. marginatus a Micromus lanosus. Jsou uvedeny poznamky k rozsli'eni druhu M. hirtus (v CSSRnebyl dosud nalezen) a M. tortricoides, se kterym byl M. hirtus dosud zamei'iovan. Material byl sbiran v letech 1956-1962 smykanim na bylinnem porostu, na ketlch a stromech a sklepavanim se stromii. Celkem bylo sebrano 2.175 jedincii, ktetl tvorI 21,3 % vsech ulovenych druhii radu Neuroptera. Nejhojnejsi druhy JSou: Hemerobilus humull [22,1 %), ktery zije hlavne v listnatych leslch a na krovinatych mfstech. Dale nasleduje H. micans (18,6 %), ktery zije v listnatych lesich zejmena na buku. Tretim nejhojnejsfm druhem je H. pini (15,6 %), ktery zije v jehlicnatych 1eslch. Druhy celedi Hemerobiidae ziji prevazne v listnatych i jehlicnatych 1eslch na stro­ mech a kerlch, jen nekolik druhii iije jen nabylinnemporostu. Jejich larvy jsou podlouhle a stIhle, ridce och1upene a nikdy si neptichytavajl zbytky vysate kotlsti na hfbetni stranu zadecku. My1ny nazor, ze larvy ce1edi Hemerobiidae velmi dobra pozname od larev celedi Chrysopidae zejmena podle toho, ze si larvy celedi Hemero­ biidae ptichytavajI kozky vysateho hmyzu na zadecek (K 1 a pal e k, 1908), je stale tradovan v nasich pNruckach a ucebnicich, i nejnovejslch, (napj\ P f e f fer 1954, 1960). Jen larvy nekolika druhii celedi Chrysopidae si ptichytavaji zbytky vysate kofisti na brbetnl stranu zadecku a ty k tomu maji take pi'izpiisobene dlouhe chlupy. Zadne larvy celedi Hemerobtidae toto prizpiisobeni nemaji, podobne jako larvy na­ sich nejbeznejslch zlatoocek Chrysopa carnea, C. phyllochroma a C. perla. * The Czechoslovak species of the Hemerobiidaeoccur mostly in woods and bushy habitats. Only some species about 6-7, may be found on herbaceous plants; they occur, however, in small trees and bushes, too. The larvae feed on aphids, coccids and other sucking insects. The same food habld applies to the images. Thirtieth species of the Hemel'obUdae have been hitherto ascertained In Cze­ choslovakia, including those quoted in the present paper. The material used for this paper was mostly collected by the author, into a lesser degree by other workers of the Institute of Entomology (Czechoslovak Academy of Sciencesl. Department of Entomology (Charles University), etc. The author useS' this opportunity to express his sincere gratitude to all these persons. As for the list of Czechoslovak speCies of the Hemerobiidae, the nomenclature 55 used by T jed e r (1941, 1961), has been followed. The generic names used by N a k a h a r a (1961) are quoted in cases of different opinion of these authors. Our material was collected during 1956-1962 by sweeping on herbaceous plants, bushes and trees, all specimens of the found Neuroptera having been collected. In the present paper only the Hemerobiidae are dealt with. REFERENCES The order Neuroptera of Central Europe was classifi~d by Bra u e r, Low (1857). The Czechoslovak·, species, including the Hemerobiidae, were studied mostly by K I a p a I e k (1895, 1901, 1903, 1904). The species of the Slovak territory are dealt with by Pongracz (1914), Mocsary (1918) and Fekete [1929). Mayer (1937, 1939) gives records of some species from Moravia and Slovakia. The latter territory was also studied by Ba I t has a r (1938 J. Some species from Moravia are quoted by Lan g (1941). The Neuroptera were keyed by Bar t 0 s (1959J. Some records may by found in Mar tin e k's paper (1960). T e y r 0 v sky (1961J added some notes to Bar t 0 S' s key. Some new and interesting records are found in Z e­ len y' s paper (1962J. Data on the bionomics of the Hemerobiidae are found e. g. in the KIa p a I e k (1908), P f e f fer (1954, 1960). European species were studied by a number of authors. They are BUr k 6 v n a (1955J. Friedrich (1953), Klapalek (1893,1898,1900,1904), Kozhantshi­ k 0 v (1953, 1956). K r ii g e r (1922 J, K ill i n g ton (1936, 1937), R e ute r (1894). Rousset (1960), Schneider [1885), Stitz [1931,1936), Tjeder (1940,1945). The Hemerobiidae of variOUS workerd parts were worked out in detail by Car pen t e r (1940), N a k a h a r a (1960) and T jed e r (1961). Notes on the bionomics and dominamce of the Hemerobiidae The larvae are fusiform, narrow, sparsely haired. Mandibles are relatively shorter and less arcuated than in the Chrysopidae. When searching for food they run on leaves of trees and bushes, moving their heads right and left. They can by easily differentiated by this behaviour from the larves of Chrysopidae. The larvae of Hemorobiidae never put the rest of their prey on the dorsal side of' abdomen; they are not even morphologically adapted for similar behaviour. It is necessary to note that in some handbooks and papers, S tit z (1931), P f e f fer (1954, 1960) quote the incorrect opinion primarily given by K I a­ pal e k (1908). The mentioned author writes that the larvae of the Hemerobii­ dae put the rest of their prey on the dorsal side of the abdomen, and that they can be easily recognized by this characteristic. This is but a mistake. Only some­ species of Chrysopidae living on tree and bushes cover their abdomen with rests of their prey, but the greatest number of Chrysopidae, and all Hemero­ biidae, do not behave like this. The Hemerobiidae are represented by 21.3 % in the total number of Neuroptera specimens from Czechoslovakia. Altogether 2,175 specimens of this family were collected. The family Chrysopidae (45.5 %) and Coniopterygidae (30.8 %) were more common. Among our specimens of various species, more females than males are re­ presented. This is probably due to the earlier death of the males, while the females, owing to oviposotion, have a longer life, and for this reason they can be more commonly found. Most Hemerobiidae have two generations, only some­ species have one generation per year. The dominance of different species among our specimens is as follows: ThE1 most common Czechoslovak species is Hemerobius humuli. It is widely distri- 56 buted, living on deciduous trees and bushes (22.1 %). The second most cqrnmon species.is H. micans [1'8.6 0/0). It occurs sometimes rather abundantly in beech woods, being the dominant species there. The third com'mon species is H. pini (15.6 % ) .. It occurs as the dominant species in coniferous woods .. The mentioned three species constituted 56.3 % of the total number of collected specimens. As for abundance, the following species may by mentioned: H. nitidulus (5.9 % J Boriomyia quadrifasciata [5.8 %) - both species occurring in coniferous woods; H. lutescens (5.3 % J - occurs in deciduous woods. H. atrifrons (3.8 % J occurs mostly on the larch, H. stigma (2.8 %) may be found in coniferous woods and B. betulina (2.3 %) in deciduous woods. All the other species are even less represented, or there single specimens only; this group includes 21 species and 17.8 % of all collected specimens.
