Question

in experiments by greene and colleagues (1987) with the tephritid fly zonosemata vittigera and the jumping spider phidippus apacheanus, carefully controlled experiments demonstrated that

Answer 1

The experiments conducted on the tephritid fly and jumping spider by Greene and colleagues is to get an understanding of the relationship existing between predator and prey.

In the experiment, they tested whether the display of the tephritid fly got disturbed and mimicked the jumping spiders' appearance as a way to deter the attack. It is found that, with the exposure of the tephritid fly to the jumping spider, the wings of the fly were kept in a perpendicular position to its body, and waving in an up and down direction is observed. Moreover, the dark bandings also appeared in the wings.

Hence, these are the changes that happened with the fly enable them to mimic the appearance of jumping spiders and help them to survive.
