NEOTROPICAL Tropical & Subtropical Moist Broadleaf Forest

The rainforests of the tropical Americas have the highest diversity of insects in the world. It has been reported that you will find more species of ants on a single tree in a Neotropical rainforest than occur across the entire country of England. 

Class Insecta

Order Orthoptera: Crickets &Katydids, and Grasshoppers 

The insects of this order are well known for their quick springing and jumping abilities, a skill possible due to the incredibly long legs that are bent back and to the side of the body. These legs are also involved in sound production; they are rubbed to create the sometimes very loud noises that males make to attract females.

Like many common names cricket and grasshopper mean different things in different places. Generally, the crickets tend to be nocturnal, have long antennae and females have an extension to the back of their body which is stuck into soil to lay eggs (ovipositor). In contrast, grasshoppers tend to be diurnal, have short antennae and females lack the ovipositor. Generally, the nocturnal crickets are duller coloured, while the diurnal grasshoppers can be brighter colours; however, in the tropical rainforest crickets are often colourful bright greens. Katydids are also known as ‘long-horned grasshoppers’, but are classified with the crickets. They are common in tropical rainforests worldwide, but because they are often high in the canopy, and many species are green and frequently shaped like the leaves and stems in amongst which they live, they can be hard to detect. Only their loud calls give away their presence.

Acrididea: 'Grasshoppers'

Family Romaleidae: 'Lubber Grasshoppers'

A family of grasshoppers found only in the Americas.

(Yarina, Amazon, Ecuador)

Tropidacris cristata, 'Red-winged Grasshoppers'. Three sub-species. At over 15cm long, they are one of the biggest insects in the world, and probably the largest of all grasshoppers. They usually have a dull reddish body, and bright red wings when opened up in flight. Their large size means people sometimes mistake them for birds when they have seen them flying in the canopy. They have spines on their back legs, and they have also been reported to given a painful bite, and using a bitter brown liquid as a defence. Found in rainforest of Central and South America.

Order Diptera

Family Tachinidae

This family includes over 8000 recorded species so far, and are found all over the world. They are particularly diverse in South America.

'Hedgehog Fly' (image by Damon Ramsey)(Wayqecha, Peru)

'Hedgehog Fly'. This group is most obvious and diverse in South America, particularly in high altitude rainforest where they may be important pollinators of flowers. The larvae are internal parasites in other insects.

Order Coleoptera, Beetles

Beetles are similar to the true bugs in their rounded appearance and their hard protective forewings that fold over the softer hindwings. However, they differ in the fact that the wings usually meet straight in the middle (to form the protective elytra) and they have efficient biting rather than sucking parts. The elytra is often shiny and produces some beautiful colours and textures. This harder layer is lifted up when the hind wings are used for flight. The high number of species of beetles is famous amongst biologists, and they are usually considered the most diverse of all animal groups.

Throughout the virus I am working in Australia on and off as local borders close, mostly in the Kimberley with Coral Expeditions (May-September). If you can't go travelling until everything settles down, then until then, here I am doing online guided walks for Noble Caledonia and online lectures for Silversea.
