first four instars they live together in a caterpillar tent). Most of the current faunistic data are collected from caterpillar observation and breeding. FAUNISTIC DATA The investigated area is situated in the Körös Valley (Békés county, Southeastern Hungary), mostly inside the delta of the confluences of rivers Fehér-Körös (White Körös), Fekete-Körös (Black Körös) and Sebes-Körös (Fast Körös). The town Gyula is found just outside the delta, south of the Fehér-Körös. The first male specimen of Eriogaster lanestris was recorded in March 1992 at a streetlight in Gyula by the author. Eriogaster catax (one male specimen) was first collected by a private light trap in Sarkad-Remete in 1990 (KOVÁCS, unpubl). No further specimens were reported from the material of the forestry light traps operating in the Körös Valley (Gerla, Sarkad-Remete, Gyula-Városerdő) (FAZEKAS 1988, SZABÓKY, pers. comm.) (Fig. 2).
