This study examined diet composition and specialisation of the Striped Legless Lizard Delma Impar, a species of conservation significance in southeastern Australia. A small sample of 25 faecal pellets was collected opportunity during the course of fauna surveys in the Derrimut Grasslands Reserve, Victoria: Their contents were examined and the invertebrate remains identified to the level of order. Invertebrate prey availability was estimated using samples collected from pitfall traps and dielary specialization was calculated using Levins (1968) standardized measure 01 niche breadth A low measure was recorded (0.05-0.07) and mainly cricket. spider and noctuid moth were found in the faecal pellets. This suggests that the Striped Legless Lizard is probably a specialized arthropod feeder. However. The small faecal pellet sample size, potential biases in the measurement of prey availability and possible uneven prey availability due to palatability constraints, may have differentially Influenced this result. Seasonal prey shifts and a flexible foraging strategy are also suggested by the results, though more detailed work is required on the feeding ecology of threatened species.
