Here's why:

* Anopheles mosquitoes are the only mosquitoes that transmit malaria.

* Female mosquitoes are the ones that bite and feed on blood, which is necessary for their eggs to develop.

* The parasite (Plasmodium) lives inside the mosquito and is transmitted to humans through the mosquito's saliva when it bites.

So, it's important to remember that not all mosquitoes carry malaria, only female Anopheles mosquitoes do.
