Developing larvae at egg site #1 (see page Pond A) are now stage 17+ (Ballister & Moore 1437), but the loss of embryos seems to be close to approximately 40% at this time. Three normally developing embryos are attached to outer jelly envelope. Defect eggs & embryos (many may have not been fertilized) remain, as would be expected, within the two jelly capsules. All strings appear opaque, whitish and fuzzy even when normal larvae are abundant. This locality harbors a very large breeding population of toads. Weather tonight clear, cool but little breeze.
