Hello friends @Indonesiahive
flies are animals that live wild, usually flies where a dirty place is where flies are, for some people flies are obviously dirty but in the medical world this fly village is useful for eliminating venom such as snakes, limpans or other venomous animals.
This fly is called an army fly because it looks like an army, so it's called an army fly, yesterday I took some photos using a cellphone, added an extreme macro lens, Hive's friend.
