Prey capture in a mantid (Gonatista grisea): does geotropy promote success?
Keyword(s):
Gonatista grisea (Fabricius) is one of many arboreal arthropods and reptiles that orient downwards to ambush prey. To investigate if orienting downwards increases hunting success, a 2 × 2 factorial experiment was performed using mantid orientation (upwards, downwards) and direction of prey approach (posterior, anterior) as factors and prey capture success as the response variable. The results indicated that the mantid captures prey equally well when oriented upwards or downwards but that it is less effective when the prey approaches posteriorly. Because prey likely climb upwards more frequently than downwards, these findings suggest that G. grisea increases its hunting success with its downwards orientation.
