Your letter to the bugman:  okay first, I would like to thank you for your service, I have deep respect for anyone whose uses their scientific knowledge to help others and incentivizes them to use/learn scientific thought
now regarding the slugs
from time to time I find these cute little slugs in my garden, I’m pretty sure this one is a adult as most I have seen have a similar size (something around 1.5 cm), oddly enough I always find them in pairs (which probably is just a coincidence), they seen to be pretty common as I have found them in several distinct locations, also their eyes are a little bit longer than that, I suppose the camera flash scared it, which led to it slightly retracting it’s eyes.
even though the picture isn’t in high-resolution, I hope it’s enough to help identify these adorable slimy creatures.

Dear Mr.K,
Thanks so much for your kind words.  Alas, we are unable to provide you with anything more than you already knew.  This is a Slug, a Mollusc in the class Gastropoda

Your letter to the bugman:  greetings Bugman.  I have found your site randomly but joyfully.  are you the Bugman of whom Albuquerque Speaks such praises ?    my daughter recently moved to ABQ.  I saw your work on a documentary, I believe & encouraged her to offer herself to volunteer as she is an avid entomologist .. with a background in pathology.  now, the accompanying image is of a foamy pod adhering to a dried plant stalk in swampland near NOLA.  a friend asks & I am curious as well.  thanks to you, for this great site… you are generous and the education opportunities your offer the seeking here on social media reaffirms my faith in humanity, yes indeed.

Egg Mass of Apple Snail

Dear Rebekah,
Thanks so much for your fervid praise, but we don’t know anything about Albuquerque Speaks.  We did feel compelled to get you a proper identification and we believe we have properly identified this as the Egg Mass of an Apple Snail in the genus 
Pomacea, and there are several invasive species. According to Featured Creatures:  “You can scrape off the egg masses and allow them to fall into the water since inundated eggs will not hatch. However, only pink egg masses should be scraped or removed. Egg masses with large, white eggs were laid by the native Florida applesnail and should be left undisturbed, as they do not pose a threat and are the principal food of the Everglades kite. Never release applesnails from aquaria into the wild (FFWCC 2006).”  ResearchGate also has an image of a pink Apple Snail Egg Mass.

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?

Slug Eggs

Dear Unintentional Gardener,
These are the eggs of a Garden Slug.  According to  “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
