Glyphyalinia wheatleyi

Life Cycle


Most terrestrial land snails, including Bright Glyph go through a life cycle that is direct (Rogers, 2009).  In direct development there is only one stage and the juvenile is just a younger, smaller version of the adult with no larval stages.  As opposed to indirect development that includes multiple larval stages (McDarby, 2008). Development can sometimes be affected by competition within the area.  Competition is usually seen within species in which resemble in size and form.  Because of this competition, it can be found that the population of land snails in a certain area can greatly decrease in terms of snails per given area (Baur and Baur, 1990). Other life cycles to be considered are those of trematodes that use land snails, such as G. wheatleyi as intermediate hosts (Gillis and Haro, 2010).
