Biorhiza pallida, also known as the oak apple gall wasp, [1] is a gall wasp species in the family Cynipidae. This species is a member of the tribe Cynipini: the oak gall wasp tribe. Cynipini is the tribe partially responsible for the formation of galls known as oak apples on oak trees. These are formed after the wasp lays eggs inside the leaf ...
Andricus foecundatrix (formerly Andricus fecundator) is a parthenogenetic gall wasp which lays a single egg within a leaf bud, using its ovipositor, to produce a gall known as an oak artichoke gall, oak hop gall, larch-cone gall or hop strobile [1] [2] The gall develops as a chemically induced distortion of leaf axillary or terminal buds on pedunculate oak (Quercus robur) or sessile oak ...
Once in the developing seed they molt, become adults, mate, and reproduce. Eggs laid by the female develop and hatch as J2 within the seed gall where they desiccate and become dormant. Dormant J2 overwinter in the seed galls until spring. They are released when galls come in contact with moist soil and hydrate.
Galls act as both the habitat, and food sources for the maker of the gall. The interior of a bedeguar gall is formed from the bud, and is composed of edible nutritious and structural tissues. Some galls act as "physiologic sinks", concentrating resources in the gall from the surrounding plant parts. [3]
Oak marble galls are also known as the bullet gall, oak nut or Devonshire gall. [5] The developing spherical galls are green at first, brown later, and mature in August. Each gall contains a central chamber, with a single female wasp larva of the asexual generation, which emerges through a 'woodworm-like' hole as an adult winged gall-wasp in ...
Take a closer look at the pros and cons of eating whole eggs (yolk and all!) to find out what's behind egg's bad reputation and whether you're missing out on some key nutrients.
Their fiber, betaine and antioxidants make them a powerful food for supporting bile production, reducing inflammation and promoting healthy digestion. Roasting or boiling beets makes them tender ...
