WELCOME …

In celebration of our first year of newsletters we launch our BUGATHON 2002 competition. Animal activity on the AIF property is at a high, still seeing Cassowary activity (see newsletter Vol.1 No.4) plus a recent visit from a pair of Giant Lace Monitors. Along with all the regular features we also look at Ant Filming; School Holiday Display and finish with Food Plants of a Selection of North East Queensland Butterflies and Moths, Part 2 - Moths.

 

BUGATHON 2002 COMPETITION

Like to win an insect kit then get into the BUGATHON 2002. It's easy to enter all you need is a camera!

Here's what to do:

Step 1. Find an interesting insect in the garden and without disturbing it take a photograph.
Step 2. Photograph the plant on which you found the insect.
Step 3. Fill out the data registration sheet when you take the photos.
Step 4. Write a poem or essay, explaining why this insect interests you.

For full competition details visit the AIF web site, BUGATHON COMPETITION page.


GIANT LACE MONITORS

While walking around the property we have often seen small Lace Monitors (Goannas). Sightings usually consist of a quick glimpse as they ran furiously across the forest floor before they disappeared up a rainforest tree. So it was with great pleasure recently that a pair of large Lace Monitors were observed.

Seen taking advantage of a strategically placed log for sunbaking upon, both monitors estimated to be around 2 metres in length appeared to be in good health.

ANT FILMING

ANT FILMING Ants were on the agenda for filming during the month of October. Mr Satochi Kuribayashi, a Japanese specialist in insect filming and in particular ants put many local species under the camera lens including Green Ants, Rattle Ants and Mangrove Ants.

LITTERBUGS - THE GIANT COCKROACH

What do you think about when you hear the word cockroach? It's probably "Gross!" Did you know that there is more than one type of cockroach? The biggest type of cockroach is the Litterbug, which can also be known as the Giant Burrowing Cockroach. The Litterbug can grow to be eight centimetres! Although these cockroaches are huge, they are actually disease free and the cleanest type of cockroach there is. So don't be scared next time you see a giant cockroach, because it just might be one of these amazing disease free creatures…..the Litterbug!

Classification

Litterbugs belong to a family called Blattidae. The Blattidae family is made-up of all cockroaches, including the Litterbug. Almost all of the cockroaches that make up this unusual family can't fly. To be part of the Blattidae family you must have:

* A flat oval shaped body
* A thorax covered by a plate that extends to the head t A mouth that can chew
* 2 compound eyes
* 6 long, hairy legs
* 2 long antennae
* A prominent cerci

Litterbugs are by far the biggest species in this special family!

Description

If you are walking around the Northern Queensland forests and discover something that looks like a large red rock, pick it up because it just might be a Litterbug. Their unusual red coloured body can easily identify these huge insects from other cockroaches. All Litterbugs have:

* Six black hairy legs
* Two antennae
* A big red body that extends onto the head
* Two compound eyes
* A thorax
* A mouth

Litterbugs can grow to be a huge eighty millimetres (eight centimetres)! They have been found to weigh up to 30 grams. Litterbugs may sound like vicious giants, but they don't bite and are just amazing creatures.

Body parts of the Litterbug

Head: The head enables the eyes and mouth to move in different directions. It is the front section of the Litterbug.
Mouth: The mouth is used to eat and chew food.
Eyes: The two compound eyes are used, so the Litterbug knows where he is going. Antennae: Litterbugs use the antennae to feel around for things.
Thorax: The thorax is like the neck for an insect. Abdomen: The rear body section of an insect.
Legs: Legs are used for scuttling and burrowing. All six of the legs are connected to the thorax, although it often doesn't look like they are.

Movement

Litterbugs are fairly fast creatures and spend their day burrowing deep into the soil To move to different places, Litterbugs either scuttle along the forest floor or dig to their destination! When eating, Litterbugs have to pick up the food with their teeth and then chew. After doing all of the moving around in a day they like to have a good rest in their chamber underground.

Life Cycle

Litterbugs are very unusual creatures. This is why they have a very different life cycle to normal cockroaches. The first stage of their life cycles is when a female gives live birth to baby Litterbugs. Slowly, these young Litterbugs turn into small nymphs, which is the next stage of the life cycle. After a few weeks these small nymphs turn into a medium nymph. The next stage of the life cycle is when the medium nymphs turn into large nymphs. Finally the Litterbugs go through the last change of the life cycle…turning into adults. After about four years the adult Litterbugs mate and the life cycle starts again.

Breeding

Litterbugs will start to breed when they reach around the age of four. A male and female Litterbug will mate. In a couple of months the female will give live birth to young Litterbugs. These baby Litterbugs are a creamy white colour. After birth the small Litterbugs scuttle under the mother. The breeding season for Litterbugs is around October. Baby Litterbugs that are bred in captivity need to be separated from parents for the first four months of their lives. This is because the parents can sometimes get very vicious towards the young Litterbugs.

Food

Litterbugs have a very simple diet. Since their habitat is the forest, they will eat anything that you can find on the forest floor. When Litterbugs go out and collect food, they look for things like leaves, twigs, grass and bark. Amazingly, Litterbugs only eat dried crunchy leaves rather than wet, fresh leaves. This is because Litterbugs gather up food that they find on the forest floor. Wet, moist leaves are on trees, which the Litterbugs can't get to!

Predators

Litterbugs aren't in very much danger of being eaten by predators. This is because they spend most of their time in their chamber underground. The only time they leave this chamber is at night-time, when collecting food. The Litterbugs main predator is birds. They swoop down from their tree silently and pick up the Litterbug with their beak. So when Litterbugs are collecting food, they try to take as short a time as possible!

Distribution and Habitat

If you are walking around the Northern Queensland forests and discover something that looks like a large red rock, pick it up because it just might be a Litterbug. Litterbugs are found in Northern Queensland. Litterbugs dig tunnels underground until they reach a depth of about one or two metres. Then they will make a small chamber. Normally, Litterbugs will add some leaves to the chamber for comfort.

Interesting facts

* Litterbugs can be the size of an average adults palm
* Litterbugs can have up to thirty babies at one time
* The Litterbug is the worlds biggest cockroach
* Litterbugs can live for up to ten years
* Every Litterbug is clean and disease free
* When living in the wild, they come out at night and gather food
* Litterbugs give live birth
* They don't bite
* Litterbugs have been found to weigh up to thirty grams, which is the same as two sparrows
* They can grow to be eight centimetres long
* Litterbugs are available as pets
* Litterbugs squeak if they are frightened
* The don't have wings like other bush cockroaches
* Litterbugs are born yellow
* Litterbugs scientific name is Macropanesthia rhinoceros

SCHOOL HOLIDAY DISPLAY

The September school holiday period was a busy time for the AIF Education program, with a public display featuring an indoor walk-through live butterfly house being conducted in Cairns. The butterfly house proved immensely popular for all ages with considerable interest shown around feeding times as well as offering a unique hands-on experience.

Many other fascinating local northern species were also well accepted in both static and live displays. Spiny Leaf Insects and Peppermint Stick Insects took many unaware visitors by surprise as they hung from the trees around them. There was still considerable hesitation shown on interacting with the Mulli grubs (Rhinoceros beetle larva) but much time was spent explaining the difference to the Wijitti grubs.

The display was a great success with visitor numbers far above expectations.

IN THE LAB

With the typical pre-wet season weather upon us, work in the lab is becoming slightly uncomfortable. Although we swelter in the humid conditions, the insects are thriving!

While most beetle tubs are full of pupa, some beetles have been emerging such as the Rhinoceros beetles, which have been coming out for some time now. Orthopteran insects have emerged in abundance such as the many species of stick insects; katydids; crickets and cockroaches. Mantids are developing with the first adults mating underway. To avoid predation, Centipede babies have been individually housed.

We are currently assisting a university student in rearing selected Katydid stock to be used in upcoming research.


RESEARCH NEWS

A new species of Buprestidae (Jewel Beetle) found here at the AIF is currently under research by Dr. Shelly Barker, University of Adelaide.

The first recorded specimen of the genus Synhoria has been collect here at the farm. The only previously known genus in this Australian Meloidae group was Horia. This bright red beetle was active during the day when captured and is suspected to be predator of native bees.

THE BUG FILES - WET TROPICS NEWSPAPER STORY

Attack of the Spider Eaters

By Sue Hasenpusch

Reprinted with the permission of Wet Tropics Management Authority.

Wasps are usually overlooked or feared. In fact, wasps are vital in controlling the number of other insects in the environment, maintaining that all-important balance between species.

In particular, hunting wasps are efficient predators of many insects including beetles, flies, crickets and caterpillars. Some are specific and hunt spiders only.

Females hunt prey for the next generation of wasp grubs, using scent to locate their prey. A female may spend hours searching the garden until her perseverance is rewarded with a juicy spider or caterpillar.

After seeking out a suitable sized victim she stings and paralyses it. Some wasps then lay their eggs directly onto or into the victim on the spot, while others grip their prey in their long legs and carry it back to the nest. After stocking up with a number of immobilised victims, the female wasps lay their eggs and the prey becomes host for the emerging grubs to feed on.

Some hunting wasps live underground and can be seen leaving an excavated burrow, while others use clay or mud to construct their homes. You might find mud nests on trees in your garden, or on the exterior walls of your home. These mud nests need not be feared or seen as home to swarming wasps. Hunting wasps are solitary - they live alone. Observing a female as she constructs her nest over several days can be interesting. Watch the huntress as she comes and goes stocking her nest and you'll soon know which insects she is culling from your garden. While solitary wasps are generally slow and docile, they will act in self-defence if they're provoked, and a sting can be painful - so keep out of their way.

Unfortunately, some other wasps are more aggressive and encountering a nest of social wasps may result in an attack. These wasps live in colonies where all the activities are shared. Within the safety of the nest lives the queen, producing eggs.

Nests of social wasps are easily identified by their paper-like appearance. They are constructed from chewed plant material and are usually attached to a plant, making them difficult to see amongst the garden foliage. Always take care around any social wasp nest- if threatened they will defend their communal home. Sometimes a nest is built in a frequently used area and is difficult to avoid, especially if small children are around. If necessary, carefully remove the nest.

Wasps are more active during the heat of the day so nests are best approached in the cooler hours. But instead of reaching for the spray can, look for a green ants nest. If there's one nearby, you can try you hand at bug warfare! The green tree ant is a fierce predator on many insects and will tackle a troublesome wasp nest with great enthusiasm. First, the green ants need to have access to the wasp nest, so attach a piece of string close to the ant nest and run it out to the wasp nest. The green ants will attack at dawn, swarming across the string. The wasps who survive will fly away and build a new nest elsewhere - hopefully well out of your way!

Remember, green ants bite too, so it's best to approach their nest in the cooler hours of the morning or evening.

The Hercules Moth of North East Queensland is the World's largest moth (an unconfirmed Innisfail specimen had a 36 cm wingspan!). Reports of the Atlas Moth are probably from mis-identification of the Hercules Moth. In Australia, the smaller Atlas Moths are rare and confined to the Darwin area.

Rainforest edges, lowland vegetated streamlines and rainforest/sclerophyll ecotones or mixed forests are the richest butterfly habitats. Flowers, which attract adult butterflies and moths often increase the usage of larval food plants when they occur in close proximity. Amongst the most attractive native flowers for Lepidopterans are Bottle Brushes, Golden Pendas, Pavetta, small Melaleucas, Umbrella Trees, Canthiums and a selection of heavy flowering Proteads and Myrtaceous plants. Some butterfly larvae require particular species of ants to be present before eggs will be deposited by adults. It should be remembered that caterpillars may damage their foodplants and fruit-piercing moths may attach edible fruits.

When planting natives to attract a variety of butterflies and moths it is important to be aware of the vigour and size of such trees as Pink Euodia and vines like October Glory. Where sufficient room is available, a combination of trees, shrubs vines and herbaceous plants is best. Of the large to medium sized trees, Pink Euodia, Red Ash, Northern Laurel, Native Limes, Cassias, Tuckeroo, Celtis, Bumble Trees and Corky Bark are particularly good. There are probably not as many outstanding small trees and shrubs but the Little Euodia, Lime Berry, Cocky Apple, Velvet Bean and Brown Birch are amongst the most useful in the region. Vines usually need support and often need to be controlled. Numerous species are excellent butterfly and moth hosts including the Native Dutchman's Pipe, Lacewing Vine, Day Moth Vine, Native Grapes, Zig Zag Vine and Cynanchum carnosum. Herbs and other ground plants such a Cunjevoi, native Dipteracanthus spp. and Hemigraphis spp., Pastel flower and Mat Rush are some of the few very good small plants for attracting butterflies and moths.

If plantings are for the purpose of creating wildlife corridors or increasing food resources for animals such as frogs, lizards, birds and insectivorous mammals, selecting plants which host the greatest range of moths and other insects should be considered. There is risk of young plants being stripped of foliage before they can withstand insect attacks, but such plants could enhance the ecological values of revegetation efforts if they survive. Eucalypts are extraordinary as they host more than 300 moth species in Australia. Acacias are also excellent hosting over 100 species. Several other local plant genera are highly significant in that they host between 10 and 50 moth species. They include Leptospermum, Lophostemom, Melaleuca, Casuarina, Cissus/Cayratia, Hibbertia, Canthium, Glochidion and Ficus.
