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.
At the shortest, a dragonfly's life-cycle from egg to death of adult is about 6 months. Some of the larger dragonflies take 6 or 7 years! Most of this time is spent in the larval form, beneath the water surface, catching other invertebrates. The small damselflies live for a couple of weeks as free-flying adults.
