Mating Slugs

Dear Don,
Your image of mating Slugs is quite stunning.  If you would like to read more about hermaphroditic mating Slugs, the Wildlife Kate blog has a nice posting that states:  “I returned a little later to see just one slug…. and no sign of the jelly, which I had presumed was some kind of slime in which the eggs were fertilised. I was wrong! On doing a little research, I discovered that this blob of jelly was in fact two slug penises, entwined! Slugs are hermaphrodite and they impregnate each other through this method and then retract their penises, laying eggs a couple of weeks later.”

Your letter to the bugman:  Hey there!
I was working over my grandmother’s weeded lawn and came across the white raspberry looking mass in the photo. It was buries about 2 inches below the soil in a cluster of weed roots.
Any idea what it would be?
Thanks!

Slug Eggs

Dear Unintentional Gardener,
These are the eggs of a Garden Slug.  According to Bumblebee.org:  “The eggs are sticky, pearly white, found in clumps, and really very pretty. You can just make out the bodies of the slugs floating in their rich supply of albumin. They are commonly found in compost bins and under plant pot saucers. They need to be in a moist environment to survive.”  There are other supporting images on Rural Ramblings and on Naturally Curious with Mary Holland where it states:  “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.”

Red Triangle Slug

Dear BaldJohn,
The postings on our site of Red Triangle Slugs,
Triboniophorus graeffei, are indeed from Australia.  Atlas of Living Australia and Australian Museum have images and some information.  We have not located any information regarding Red Triangle Slugs being introduced into North America.  With global travel as easy as it is right now, introduction of exotic species to new habitats is a common occurrence.  It is possible that this Red Triangle Slug has been accidentally or purposely introduced to Virginia.  We will try to monitor any other North American sightings.  If the new habitat is hostile, the Red Triangle Slug will not become established in this location.

Hi there! I see these beetles wandering the ground and on and under rotten logs all over Southeast Alaska and the rainforests of the Pacific Northwest (WA, OR, British Columbia) and I have not been able to ID them! They have these wonderful purpleish abdomens and are maybe an inch long or less. This one was found with a baby banana slug in its jaws! What is it?

Snail Eating Ground Beetle with immature Banana Slug

Dear Mike,
Your image is gorgeous.  We have several images on our site of Snail Hunters or Snail Eating Ground Beetles in the genus
Scaphinotus, but your image is the only one showing its preferred prey.  According to BugGuide:  “55 spp. in 9 subgenera total, all in our area.”  Several species are known from Alaska, including Scaphinotus angusticollis which is pictured on BugGuide and Scaphinotus marginatus which is also pictured on BugGuide.  Both species look very similar to your individual and we are not confident enough to provide an exact species identification for you.  According to Bugs of the Month:  “Scaphinotus angusticollis is large (satisfyingly so) and black, with a beauteous purple or greenish sheen in sunlight. The thorax is peculiarly shaped, turned up at the outer edges (a bit like a satellite dish), the legs are quite long and slender and the head is distinctly narrow and elongate. Truly the Afghan hound of the carabid world. The narrow head is an adaptation to eating snails from the shell. Now there are shelled snails in forests around these parts, but with forest clearing and the introduction of non-native pests, shelled snails are less frequent and slugs abound.”

Wow thank you for the thorough reply! They really are quite beautiful, and now I know that the beetles I see eating snails and on the ground are snail eating ground beetles 🙂 You are right, those two species are nearly identical, I guess if I was on the spotI would tell someone it was Angusticolus.

Thanks again!
Stay Curious

Dear Bugman,
I found these little group of clear globby things on some potted soil under another pot of soil I had placed there weeks before.  I assume they are larvae of some sort but there were no markings that I could see indicative of what they were.  Do you know?

Leopard Slug

Leopard Slug

Dear Michelle,
We are pretty confident this is a Leopard Slug,
Limax maximus, and according to the article “Giant slugs slither into Saint John” on CBC News:  “Donald McAlpine, research curator of zoology at the New Brunswick Museum in Saint John, said the giant slugs are commonly known as the giant spotted leopard slug because of their markings.  ‘These are by far the largest slug in this region, probably one of the largest, if not the largest slug in Canada,’ McAlpine said.  McAlpine said the slugs thrive in damp, dark places.”  According to the Fairfax County Public Schools site:  “Leopard Slugs were introduced to America, but are now common. They grow to four inches. They are usually grayish yellow with black spots or bands. Often they are wrinkled.”  According to The Living World of Molluscs:  “The leopard slug is a commensal species, which, apart from its habitats in forests, often may be found in cellars and in cultivated areas. While its original home was in Southern and Western Europe, today it not only occurs over nearly all of Europe, but also has been introduced Overseas with food transports.”
