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.
These are the four distinct stages in an average house fly's life: 1  Egg: Depending on the size of a female house fly, she can lay up to 500 eggs in a three to four day period.2  Eggs are white in color and are usually less than half and inch in size.3  Larvae: Larvae are commonly referred to as maggots. This process take about three to six days and is where the maggot encases inself in a reddish-brown skin where the final stages of development take place. 2  Adult: Once the adult house fly hatches from the pupal stage, it has an approximate life span of 15 to 30 days.
