They are herbivorous like the majority of (but not all) grasshopper species and when they are present in large numbers they can be a major pest, destroying crops as well as wild plant populations. Since purchasing my first ever Tropidacris nymphs in May 2012 they have rapidly become one of my favourite insect species, largely due to their beauty but also because of their size, speed of growth and their calm temperament which allows children as well as myself to handle them (where I deem it appropriate of course)!
Grasshoppers Species :
- Tropidacris collaris :
This species is one of the largest, if not the largest, grasshopper species in the world and they really are very impressive in the flesh! They are found throughout South America from Colombia down to central Argentina and are found in a wide variety of habitats from humid tropical rainforests to dry arid grasslands. They have very beautiful wings as adults as you can see here:
Despite being largely a beautifully intense green colour as adults, these remarkable insects certainly do not start out in life looking like this. In fact as small nymphs, as in the pictures below, there isn't even a hint of green to be seen as they are just a mix of black and orange!
As they moult through their life stages they do develop more colouration but this starts out as just a mix of black, orange and yellow:
When they reach their subadult life stage, which means they are one moult away from maturity (and full wing development), they are extremely attractive as you can see below:
As they get larger they develop formidable looking spines on their back legs which can be used in a kicking action to protect themselves from danger; these are quite sharp as seen here:
As they approach the final moult of their life cycle the green colouration of the soon-to-emerge adult exoskeleton is clearly visible through the subadult one. This is very clear in the pictures below, which are of the same individual at the same life stage but just a couple of weeks apart!
Here are just a small selection of the empty exoskeletons (exuviae) left behind as the grasshopper nymphs moult through the stages of their life cycle:
The final moulted exoskeleton left behind by a newly-matured adult is a quite remarkable thing in itself. Here it is!
I'm sure you'll agree that this is a very special insect species and they certainly have to be seen to be believed! Now that I am keeping them I will hope never to be without them, such is my admiration for the species in every way!

Distribution: Panama, Costa Rica
Stock from: Costa Rica
Size: ♂/♀: ca. 10 mm
General Care: 23-28°C, 70-90% rel. humidity
Feeding: bramble, buddleja, Solanaceae

Other Sites :
- ACRIDA BICOLOR (THUNBERG, 1815)
Locusts two-tone / Acrida bicolor - kind of orthoptera insects of the family of these locusts. The body length of 70-100 mm in females, males - 35-60 mm. The legs are long and straight, because of what they look similar to the mantis. Rather cautious insect. If his scare, it will fly or jump to a new position and solidify it in the position in which to land. However, some legs can not touch the surface, and then the insect posture is very exotic. Acrida bicolor males make loud (louder than in females) sounds. Males can chirp wings in flight (10-15 kHz frequency chirping); on the ground and the plants they use tegmino femoral-acoustic device (friction convex keel on the inside of the rear thigh rough bulging veins on the wing cases). Females, in turn, emit soft sounds tibia-tegrninal stridulatory apparatus.Males signals usually consist of one or two phases is rarely 4-5; the average duration of signals - 0.6-1.6 seconds, the following intervals 2,3-16,5 seconds (usually 3-6). Beeps, male pauses for a long time. Signals are issued by single males and females, who found the Lady, but in some cases males mates may not emit signals. During clashes aggressive males demonstratively move its hind legs: Both male and lift them are arranged, moving against each other. On the other locusts differ greatly elongated head and short antennae flattened. Body elongated, slender, green, with reddish-brown stripes and spots. The hind legs are very long. Wings longer than the abdomen. Living in the southern regions among the grass and shrub vegetation. The unusual shape of the body and the green color makes locusts unobtrusive for her enemies among the faded greenish-yellow grass.
Other genus :
