All damselfly species of the family Calopterygidae ; the wolf spider of the family Lycosidae ; and the tiger beetle of the genus Cicindela are three types of insects that I often find in rocky river/tributary environments.
That observation led me to believe that the insect's habitat existed in such an environment.
Instead of being small in stature, the last insect has a peculiar and frightening face.
I recently caught golden-spotted tiger beetles (Cicindela aurulenta) along the Blang Kolam river in North Aceh, and this is a species of tiger beetle that belongs to the family Carabidae.
The golden-spotted tiger beetle has strong serrated jaws, adores hunting ants, and frequently steals ant eggs. It possessed slender legs that allowed it to move rapidly and a pair of wings that allowed it to fly low.
Because of their lethal jaws, several insects are scared of jumping spiders and other kinds of spiders. The tiger beetle, on the other hand, is an anomaly; I've seen it fight with a jumping spider, with the latter becoming prey.
