Maturation feeding habits of tiny beetles (4-6 mm) on sunflower heads have been observed in comparative studies involving different sunflower varieties in industrial scale sunflower fields in 1994. When determining these beetles, it has been established that they belong to the species of the group (Coleoptera, Heteromera) to the family of Coleoptera, Anthicidae, and to the two genera Notoxus and Formicomus. Formicomus pedestris ROSSI., Notoxus brachycerus FALD., Notoxus appendicinus DESBR. were the most frequent species, as contrary to the beetle population observed in maize fields where the dominant species were Notoxus brachycerus FALD. and Notoxus appendicinus DESBR. Formicomus pedestris ROSSI. had “only” the third place in terms of population density. Each of the three species starts its maturation feeding on sunflower heads at the end of July or at the beginning of August. At first, the beetles consume pollen and later on they hollow out the seeds. It happens that as many as 15-20 beetles are seen feeding on a single flower head. Based on literature data, mass appearance of the beetles of the Coleoptera, (Anthiciadae) species is expected on cadavers of Meloe species (Meloe proscarabeus L., Meloe violaceus MRSH, Meloe variegatus DON.) and of Meloidae species (Coleoptera, Meloiade), for example Cerocoma schaefferi L., Lytta vesicatoria L. and Epicauta rufidorsum GOEZE, that contain chantarid ine, i.e., they are considered as necrophagous species. Damages on plants caused by these species were reported in the works of Horváth (1995a, 1995b, 2000, 2002). It needs further research to establish if feeding of these Anthicidae species, which were considered as necrophagous species, on maize and sunflower really reflects a new form of damage or it should be considered as feeding on substitute aliments forced by the drought period. Nevertheless, the damage caused by these insects in the year 2000 was most significant ever.
