individual who seemingly taken with nets for determining the
population of ladybugs in the area. To calculate the coordinates and the altitude
of where the samples were taken using a GPS (global position system) and

Source.
The results showed that A. spinidens can be found in
various places with different heights. However
abundance varies and is generally low. In the carrot crop
