Posts Tagged ‘Acris crepitans’

Following the lead of fellow photographer Steve Gingold, I decided that today is a Frog Friday. I spotted these Eastern Cricket Frog (Acris crepitans), one of the smallest frogs in Virginia, on Monday as I was exploring in Prince William County. I really like frogs and was happy to capture some of the cool details of these frogs in these shots, like their tiny toes.

Be sure to check out Steve’s blog posting for today entitled Frog Friday—before and after. While you are there, I encourage you to poke about on his site—Steve has an amazing array of nature photos that he has taken, primarily in the western part of Massachusetts.

It was sunny and warm on Monday, so I went off in search of dragonflies. There has already been at least one sighting of a dragonfly this month in Virginia, but it realistically is still a bit early for any to appear in the northern part of the state where I live. I searched diligently at a pond and at several small streams in Prince William County, but did not find any dragonflies or damselflies.

I was happy, however, to spot several Eastern Cricket Frogs (Acris crepitans crepitans). These frogs are tiny, with a length of about 5/8 to 1-3/8 inches (16-35 mm). One of the most distinctive things about this species is the male mating call that resembles the sound of two stones being hit together or perhaps is similar to the sound of a cricket.

According to the Virginia Herpetological Society, “This species prefers grassy margins of ponds, ditches and wetlands. Permanent bodies of water with emergent or shoreline vegetation and exposure to the sun are preferred habitat,” a perfect description of the locations where I spotted these frogs.

Each year I am confused when researching this species, because I see references to Eastern Cricket Frogs and Northern Cricket Frogs used almost interchangeably. If I understand it correctly Northern Cricket Frog (Acris crepitans) is the species name and Eastern Cricket Frog (Acris crepitans crepitans) is one of the subspecies.

As you can see from these images, cricket frogs blend in really well with their surroundings. If I had not seen these frogs jump to their new locations, I am pretty sure that I would not have seen them. I walked around all day with my 180mm macro lens attached to my camera and it served me well to capture some of the details on the bodies of the little frogs. I attempted to get as low as I could and to shoot from the side in order to get as much of the frog in focus as I could, so muddy knees were inevitably one of the “benefits” of getting these shots.

As temperatures rise, the springtime air is frequently filled with the sounds of frogs, ranging all the way from the high-pitched choruses of spring peepers to the solitary bass notes of croaking bullfrogs. When I walk along the edge of marshes and ponds at this time of the year, the ground in front of me often seems to explode as well-camouflaged frogs arc through the air seeking to escape me.

On Monday as I wandered about in Prince William Forest Park, I spotted quite a number of tiny frogs at the edge of the water, but did not hear them calling, so I had to rely on their physical appearance to identify them. On the basis of the dark triangle between their eyes and their other markings, I believe the frogs in the photos below are both Eastern Cricket frogs (Acris crepitans crepitans).

Eastern Cricket frogs are small frogs,  reaching lengths of 5/8 to 1-3/8 inches (16-35 mm), which make them a challenge to photograph. According to the Virginia Herpetological Society, part of the scientific name for the species is derived from the Latin word crepit which means “rattle” and the call of these frogs sounds like pebbles being clicked together. Perhaps they will be calling, the next time that I visit the park.

The evidence is mounting that spring is really here. What are your favorite signs of the arrival of spring?

The frog in the photo does have a few spots, but the spots on the leaves are what really draw my attention to this image—they provide an almost visually perfect background for the main subject. I spotted this little frog earlier this week while hunting for dragonflies in Prince William County, Virginia.

I believe that this is an Eastern Cricket Frog (Acris crepitans crepitans), but was a little confused when I saw repeated references to a Northern Cricket Frog.  I think I finally sorted it out in my mind and if I understand it correctly the Eastern Cricket Frog is one of the subspecies of the Northern Cricket Frog (Acris crepitans). Logically it seems odd that east would be a subset of north, but that seems to be the case here.

Yesterday I captured this shot of an Eastern Cricket Frog (Acris crepitans) while exploring a seepy area in Prince William County, Virginia. The frog was tiny, only an inch or so (25 mm) in length. I was thankful for the green markings or I might otherwise have missed seeing the frog. The markings look very much like an arrow point towards the frog’s head. They also gave me something on which to focus since the rest of the frog’s body was pretty well camouflaged.

Frogs have begun to sing their springtime songs. Although they are loud, most of the frogs are small and well-hidden. I was happy to spot this tiny one, which I believe is an Eastern Cricket Frog (Acris crepitans), last Wednesday at Prince William Forest Park in Triangle, Virginia.

According to the Virginia Herpetological website, the Eastern Cricket Frog, which some other sources call the Northern Cricket Frog, is 5/8 to 1-3/8 inches  in length (16-35 mm). I am pretty certain that I would not have been able to spot the little frog if it had not jumped into the air and landed at a spot that I could see. Even then, I had trouble finding it in the viewfinder of my extended telephoto lens.

The referenced website notes that the male mating call resembles the sound of two stones being hit together and a single call usually lasts through 20-30 beats. Is it music? You will have to answer that question for yourself, but I suspect that the call is music to the ears of lady frogs.

Perched at the edge of a lily pad, this frog at Lilypons Water Gardens was so small that I doubt I would have seen it by myself. However, one of my sharp-eyed fellow photographers spotted it and served as the hand model for the shot with the penny.

A helpful Facebook reader suggested that this is probably a Northern Cricket frog (Acris crepitans) and it certainly does look like the photos that I can find on the internet. Judging from the size of the penny, which is 3/4 of an inch in diameter (19 mm), I’d guess that the frog was less than 3/8 of an inch (9.5 mm) in size.

My fellow photographer tried to move the penny slowly into position, but, as I suspected would happen, the frog jumped away shortly after the second shot below. I would have liked to capture the frog in motion, but ended up instead with a shot of the vacant lily pad—the frog had jumped right out of the frame.
