Stinging Arthropods
- Honeybee, Brown recluse spider, Black widow spider, and Scorpion are examples of venomous arthropods that can inflict painful stings.
- Hymenoptera (ants, bees, and wasps) stings can cause painful reactions.
Bot Fly Life Cycle
- Bot fly larvae capture another Dipteran fly (such as a mosquito) and glue its eggs along the abdomen of the carrier fly.
- While the mosquito is feeding, bot larvae penetrate the skin.
- The life cycle of bot fly takes 3 to 4 months.
