Copulation

Great Blue Herons Mating

4-15-15  great blue herons copulating2  IMG_8954Great Blue Herons have returned to their nesting colonies in the Northeast and their breeding season is underway. These birds are monogamous for the duration of any given breeding season. A study found that most Great Blue Herons choose a new mate every year. After elaborate courtship displays have taken place, the pair copulates, frequently on the nest, and usually in the early morning or evening, as the female is away from the nest mid-day.

Grasshoppers Mating and Laying Eggs

9-23-13 mating grasshoppers 137Grasshoppers typically mate in late summer and fall. If it’s a short-horned grasshopper (pictured), the smaller male mounts the female (female long-horned grasshoppers mount the males). The male short-horned grasshopper often remains riding the female for long periods in order to ensure paternity. When the eggs are fully formed, the female pushes the ovipositor at the end of her abdomen ½” to 2” into the ground and produces a glue-like secretion that cements the soil around the egg mass, forming a protective “pod.” Each pod may contain 25 to 150 eggs, depending on the species of grasshopper. Grasshoppers which deposit masses containing few eggs usually lay more pods to compensate. A female may lay as many as 300 eggs which overwinter and hatch in the spring.
