La Rana Sabanera: Dendropsophus molitor

When we visited Bogotá in 2018, Wakanomori noticed that the manhole covers had frogs on them:



I always meant to find out the story behind the frog--was it a particular frog? Why a frog? But I never did.

Then the other day, Juegasiempre (also known as DjLu), one of the graffiti artists/muralistas whose work we became acquainted with on that trip, posted this beautiful frog on Twitter: la rana sabenera, Dendropsophus molitor. (Wikipedia tells me in English it's called the green dotted tree frog.) He posted that it used to be very common in the ravines of Bogotá, but now you can hardly find it. (Original tweet here.)

La Rana Sabanera, Dendropsophus molitor

I took it into my head that this MUST be the frog on the manhole covers and finally set about to find the answer.

... Well, it's not. The manhole frog is just a generalized frog, not any particular frog, but I found out that frogs have been on Bogotá's manhole covers for more than a hundred years, getting redesigns now and then. Some people thought the design was of a toad (sapo), so the workers for the Empresa de Acueducto y Alcantarillado (Bogota's water and sewer company) would sometimes be called sapos. This is unfortunate because several years of watching telenovelas has taught me that that's also what you call a snitch.

There's a Facegroup page for people who want to preserve them--it's got some photos:





As for D. molitor, it's found only in Colombia. Females are larger than males, and they can grow to be about 70 mm. They can be green or brown, and some have stripes or lines that can be black, yellow, or blue. Although Wikipedia lists it as a species of least concern, one article I found said it's threatened in parts of Colombia by the introduction of another type of frog that competes for the same habitat.

Here's a cutie from Wikipedia (link):



Live long and prosper, little guy!

Thank you for the adorable photos and info! I like that their access covers have frogs to remind people to care for the environment.

In the Chilean Spanish I learned as a kid, ranas are toads and sapos are frogs. I guess my parents had it backwards?! Or I got my meanings crossed somewhere along the way.

Thank you for sharing! ^_^

I saw a green and gold striped frog in my frog pond this morning - it was almost certainly a Motorbike Frog. [They come in a wide variety of colours, including green and gold stripes]

That's so neat! Is there a reason for it, or did the city a hundred years ago just think it looked good? (If so, they were right.)

As for D. molitor, it's found only in Colombia.

It's very beautiful.

I have to admit that drain covers also fascinate me!

Beautiful frogs.

Do you have spring peepers out your way? I miss them.

What a cool-looking frog. And what a funny name.

Not knowing you were from Australia--and generally not paying attention to the link or title info--when I read the first line of the article ("The south-west's most commonly encountered frog), I thought, "huh, sad, but I don't think I ever saw one growing up." I grew up in the U.S. Southwest. :D

I don't have the time to dig up photos of the kiddos handling frogs and newts, but I am so happy that we took time to build a small pond in our garden that holds water year round. It is so heartbreaking when the frogs and toads lay their eggs en masse in our seasonal pond, only to have it dry up before they all hatch and complete their metamorphsis.

Back in the day, when I collected things, I collecting ting frog figurines because I have always had a love for frogs. Don't know where it came from; just always found them fascinating and beautiful, from their life-cycle, looks, and songs.

I have never heard the song, but I like it. I do wonder why there are pills scattered all over that album cover image... :-/

Yes, it is the two-toned, shiny look that really gives that medical vibe, not really like Mike & Ike for example.

There have been cases of people calling police on "bikies hooning around at 3am" that turned out to be frogs!

*LOL* I can imagine how an army/chorus of Motorbike frogs would sound. In a book I recently read with my kids about becoming a spy, the author recounts an episode when the US wanted to install bugs in a building in Africa. Fearful that the noise of the drills at night would alert neighbors to the nefarious activity, someone had the idea to collect bags of bullfrogs and release them around the building so that their croaking would mask the operation's noise. The plan worked, and thanks to the bullfrogs, no one reported the incident.

Also check out the call of one of the other frogs in my suburb, the moaning frog!

There are some great frogs in my state

not in my suburb, but these two are amazing

Hooting frog
A low pitched owl-like 'hoot' repeated slowly.
https://museum.wa.gov.au/explore/frogwatch/frogs/hooting-frog

Quacking frog
Similar to the sound of a duck quacking. Often call in discrete bursts, and males will mirror the number of quacks a neighbor gives.
