[7] It has been hypothesized that this could be due to recent pressures, such as the distance between populations, high insecticide use, or mountain ranges that act as gene flow barriers.

Studies suggest that this is due to these mosquitoes showing excellent dispersal abilities, opportunistic feeding, and niche plasticity.

[7] As well, other species in the genus Anopheles are specialists with small populations, specific habitat requirements, and limited dispersal and distribution methods.

Females can fly up to 32 kilometres,[5] and specimens have been found at almost 2000 meters altitude, meaning that mountain ranges would not separate these populations as easily as other Anopheles mosquitoes.

[7] The conclusions drawn from this research was that the differences found between A. albimanus populations were not due to recent events, but rather, Pleistocene divergence followed by re-colonization and expansion.

[8] Anopheles albimanus are seasonally abundant mosquitoes that are primarily active at dawn and dusk (crepuscular), prefer to feed outdoors (exophagic), and tend to live outside (exophilic).

[10] These mosquitoes undergo holometabolous development, meaning that their life cycle includes egg, larva, pupa, and adult stages.

If a habitat is seeing an absence of larvae, this may be due to females being selective for locations with richer food sources or protection from predation.

[5] During the wet season in Central America, larvae are found in rivers, marshes, irrigation canals, and several other water habitats, both permanent and temporary.

[4][9][10] In countries such as Belize, they are considered a secondary vector because they prefer not to enter human homes, and rather, feed on domestic animals.

[4] The parasite and the blood itself interact with the lining of the midgut, eliciting stress and digestion responses in the mosquito, as well as immune reactions.

[12] These changes in the midgut evolved to cope with the invasion of microorganisms, free radical formation, and digestion of the blood meal.

[10] By studying these topics, more insight may be gained to increase the understanding of malaria, as well as the effects that control measures would have on the reduction of both the vectors and the spread of the disease.
