Female ticks deposit large egg clusters that range in size from hundreds to thousands. These egg clusters are restricted to a deposition site as they are stationary, usually under leaf litter and other debris. In some habitats, these sites can be exposed to periodic flooding.

- Mosquitoes in semi-arid regions adapt to drought by increasing their blood-feeding behavior, especially after prolonged dry periods.
- Following a blood meal, these mosquitoes can survive for up to twenty days without water by refeeding, which helps them with hydration and nutrient needs without affecting egg production.
- The changes in mosquito behavior during dry spells, like increased activity and sensitivity to CO2, are linked to higher survival rates and potentially greater transmission of diseases, such as arboviruses, during such dry conditions.
Female ticks deposit large egg clusters that range in size from hundreds to thousands. These clusters are restricted to a deposition site, usually under leaf litter and other debris. These sites can be exposed to periodic flooding, where the cluster of tick eggs can float to the surface or remain underneath organic debris entirely underwater.

We sequenced the genome and transcriptome of the viviparous Pacific beetle-mimic cockroach and performed comparative analyses with two other viviparous insect lineages, tsetse flies and aphids, to unravel the basis underlying the transition to viviparity in insects. We identified pathways undergoing adaptive evolution for insects, involved in urogenital remodeling, tracheal system, heart development, and nutrient metabolism.
