Comments: Sometimes called âAsh-leaved Mapleâ because of its non-typical leaves, , Box Elder is technically considered a maple tree (Acer genus). Its lumber is softer, weaker, and lighter than almost all other species of maple, and Box Elderâs overall strength, as well as itâs strength-to-weight ratio are poor. Related Species:
Under room temperature (about 20 Â°C), the black blow fly Phormia regina can change from egg to pupa in 150â266 hours (six to 11 days). When the third larval stage is complete, it will leave the corpse and burrow into the ground to pupate, emerging as an adult seven to 14 days later.
The housefly life cycle closely mirrors that of most insects: a basic cycle that begins with an egg, then develops through a larva phase, a pupa phase, and finally, into an adult. During a warm summer -- optimal conditions for a housefly -- the cycle, from fertilized egg to adult, spans a mere seven to 10 days. new adult housefly has, at most, three months to reproduce before it dies. With so many predators, a housefly's average lifespan is even shorter: 21 days. Luckily for the housefly, the phrase breeding like flies isn't just a figure of speech.
