Insects As mentioned in Al-Quran بِسۡمِ اللّٰهِ الرَّحۡمٰنِ الرَّحِيۡم Mosquito - A sign for those who believe Al-Baqarah 2:26 Certainly, Allah disdains not to describe the example of that of a mosquito, or of that even more insignificant than this. So as for those who believe, they know that this is the truth from their Lord. And as for those who disbelieve, they say: What did Allah intend by this as an example. He misleads many thereby, and He guides many thereby. And He misleads not thereby except those who are disobedient.
Bee - Honey - A sign and cure for mankind AnNahal 16:68-69 And your Lord inspired to the bee, (saying) that: Set up hives in the mountains, and in the trees, and in that which they erect (the trellises).
Then eat of all the fruits, and follow the ways of your Lord, made smooth (for you). There comes forth from their bellies a drink of varying colors, wherein is healing for mankind. Certainly, in this is a sure sign for a people who give thought.
Ant - Wisdom for the community An-Namal 27:17-19 And there were gathered before Solomon his armies of the jinn and men, and the birds, and they were set in battle order.
Until, when they came upon the valley of the ants, an ant said: O ants, enter your dwellings lest Solomon and his armies crush you, while they are not perceiving.
So he (Solomon) smiled, laughing at her speech, and said: My Lord, bestow upon me that I may be thankful for your favor with which You have favored upon me and upon my parents, and that I may do righteous deeds that will please You. And admit me by Your mercy among Your righteous slaves.
Termite - Death reminder for a King Saba 34:14 Then, when We decreed death for him (Solomon), nothing informed them (jinn) of his death except a creeping creature of the earth, which gnawed away his staff. So when he fell down, the jinn saw clearly that if they had known the unseen, they would not have remained in the humiliating punishment.
Fly – A reminder for those who commit shirk AlHajj 22:73 O mankind, a parable is set forth, so listen to it. Indeed, those whom you call other than Allah cannot create a fly though they gather together for it. And if the fly snatched away a thing from them, they would have no power to release it from him (the fly). Weak are (both) the seeker and the sought.
Spider - A lesson for those who commit shirk Al-Ankaboot 29:41 The likeness of those who have taken protectors other than Allah is as the likeness of the spider, who takes (builds) a house. And indeed, the frailest of all houses is the spider’s house. If they (only) knew.
Locust-Lice - A punishment for Pharaoh Al-Aaraf 07:133 Then We sent on them (people of Pharaoh) the flood, and the locusts, and the lice, and the frogs, and the blood, as manifest signs. Yet they remained arrogant, and they were a criminal people.
