Slugs

Snail and Slug Eggs

Snails and slugs are very similar, except for a slug’s lack of a shell.  Both are hermaphroditic, possessing male and female reproductive organs.  In some species an individual may behave as a male for a while, then as a female. In a few species, self-fertilization occurs. Some species mate and lay eggs in the spring, some in the fall. Most snails and slugs that hatch in the spring can begin egg laying in the fall. The eggs of both snails and slugs are tiny, white or cream-colored, round and laid in roughly one-inch diameter clusters of 30 or so eggs. Look for these clusters under rotting logs, where they are protected from drying out as well as from freezing.  (Remember to place the log back exactly as you found it.)


Naturally Curious wins National Outdoor Book Award

I am delighted to be able to tell you that this morning I learned that NATURALLY CURIOUS won the Nature Guidebook category of the 2011 National Outdoor Book Awards.  I’m honored and humbled by this recognition.   http://www.noba-web.org/books11.htm


Millipede Mystery

This morning I discovered the exoskeletons of nine millipedes clumped together at the top of a rotting stump.  They were covered with slug slime, with said slug still at the scene. Presumably its stomach was full of millipede innards.  If anyone can explain this phenomenon to me, I would be most grateful!


Slug Eggs

If you spend enough time looking under rotting logs, you’re bound to come across the tiny, pearly white eggs of a slug. With the right climate conditions, slugs will mate and lay eggs twice in a summer — once early in the spring, and once in late summer. Thirty to forty days after mating, the female slug lays her eggs under leaves, mulch, or in some other cool and moist location. They will hatch in 10 to 100 days — the length of time slug eggs take to hatch depends upon the temperature – the warmer it is, the faster they hatch.


Eyelash Cup Fungus

Fungi can be divided into two groups – basidiomycetes and ascomycetes.  Basidiomycetes (gilled mushrooms, coral fungus, hedgehog  mushrooms, puffballs, bird’s nest fungus) produce spores on the surface of microscopic cells called basidea.  Ascomycetes (morels, cup fungi, stinkhorns) produce their spores within microscopic sacs (asci).  The slug in this photograph is dining on an ascomycete  — eyelash cup fungus (Scutellinia scutellata), the rim of which bears many stiff, eyelash-like hairs.


Snails and Slugs

Snails and slugs are grouped together as gastropods – a class of Mollusks that includes land, freshwater and sea snails and slugs.  The term “snail” is used for species with an external shell large enough for the soft parts to withdraw completely into it. Those gastropods without a shell, and those with only a very reduced or internal shell, are usually known as “slugs.” We refer to many marine gastropods as seashells, including whelks, conchs, cowries, olives, cone shells, figs and tulips.  While many gastropods are herbivorous grazers, several groups are carnivores, capable of drilling through the skeleton of their prey.
