Field observations of the adult European skipper, Thymelicus lineola (Ochs), feeding on concentrated nectars (40–65% sucrose) from a variety of flower species led us to question recent literature stating that butterflies feed primarily, and most effectively, on dilute nectars. Rate of sucrose solution intake, volume consumed and feeding duration were measured for males and females at 25 and 35°C under laboratory conditions. As sucrose concentration increased, the volume of solution ingested per… CONTINUE READING
