title: Is the butterfly Tomares ballus (Lepidoptera: Lycaenidae) a potential pest of Lens culinaris (Leguminosae)?
abstract: The lentil (Lens culinaris) is identified as a new host plant of the lepidopteran Tomares ballus. Five larvae of T. ballus were found on 19 May, 2007 in a crop of "castellana" lentils in Toledo Province, Spain and reared in the laboratory. The larval brown spiracles are slightly darker than the rest of the pupa. Traditional cultural practices reduce the insect's probability of completing its life-cycle. We present flight phenology data for T. ballus from the unedited Atlamar database (1,073 records from 1887 to 2003), based on the 438 records for which the year, month and day are known. This period coincides with the flowering and formation of the legumes of various species of leguminosae, such as lentils. The peak activity of the imagos occurs in the second half of March and the first half of April, and the last larvae must be present in the field until the beginning of June.
