Low density of ant lion larva (Myrmeleon crudelis) in ant-acacia clearings: High predation risk or inadequate substrate?

We experimentally determined whether the low density of antlion larvae found in ant-acacia clearings is due to high levels of ant predation or an inadequate substrate for pit-trap construction. Pit establishment was more affected by soil improvement than by the exclusion of ants, suggesting that soi...
