Hawks

Every night when conditions are suitable I run at least one Mercury Vapour Moth Trap. The diversity over here is amazing - Australia has over 30000 species of moths of which probably only 15000 have been formally described and of these probably only 10000 have photos anywhere online. To date in the garden I have recorded over 1000 species - not many in Australian terms but to put it i a UK perspective, the UK list including both macro (large) and micro (small) moths is only 3500ish!
One of the most iconic groups of moths the world over is Sphingidae or the Hawkmoths. Australia has 86 species and to date in the garden I have caught 44 of them - again to put it in perspective the UK has a total of 15-20 spp on its list including extreme rarities, I can catch 15 species a night here!
Here are a few photos of some of them...

Agrius convolvuli - a species with an extensive global distribution. In the UK this is a migratory species where as over here it i a common resident

Agrius godarti - similar to the previous species but instead of having pink on the abdomen it has off white - the hind wing is different as well

Ambulyx dohertyi - this species shows obviosu sexual dimorphism, the female is the darker specimen on top. These are a large species with a wingspan in excess of 4 inches

Amblyx wildei - the second of the two Ambulyx species that occurs here. Unlike dohertyi this is a very scarce species - I have only caught two individuals. The male is the upper of the two in the photograph

Pseudoangonyx excellens - I have only caught one individual of this species and according to a friend (who is the curator of Sphingide at the Natural History Museum in London) this is the furthest south that this species has been recorded

Angonyx papuana - not a common species but more common that the previous one. I have caught four individuals of this species since late December 2016

Cephonodes kingi - one of four Cephonodes species that occur in Australia. When freshly emerged the forewings of all Cephonodes are fully scaled but as soon as they fly the scales abrade and the wings become clear.

Daphnis moorei - a large species with a wingspan of over 4 inches; a regular visitor to the trap

Daphnis placida - the smallest of the three Daphnis species that I trap and probably the most common.

Daphnis protrudens -I have ony caught five individuals of this species, it is slightly largr than moorei

Eupanacra splendens - a scarce species at the trap

Gnathothlibus eras - one of two Gnathothlibus species that I catch, the other Gnathothlibus australiensis is only separable by the length of hairs on the front legs of the males....

Hippotion boerhaviae - a small species (wingspan just two - three inches) that is uncommon at the trap

Hippotion brennus - a reasonably common species in the garden, as with all Hippotion a small species with a wingspan of two to three inches

Hippotion celerio - another species with a very large global distribution; although I never saw it there it has been recorded from the UK and is widespread in the Mediterranean

Hippotion johanna - at one stage this was thought to be a sub species of brennus but it lacks the white line on th thorax (just behind the head). I have only caught one specimen of this species

Hippotion rosetta - a very common species at the trap and one that is similar to the much scarcer Hi.boerhaviae

Hippotion scrofa - a species that is very common further south in Australia but one that only occurs in small numbers in the garden here

Hippotion velox - the largest of the Hippotions that I catch; a regular visitor n small numbers

Hyles livornicoides - there are several species of very similar Hyles across the globe, this is the Australian version. It can turn up in huge numbers - peak count in the trap over 120 individuals

Macroglossum dohertyi - a small species with a wingspan of no more than two inches.  scarce visitor to the garden - in fact only seen in Yorkeys

Macroglossum hirundo - the commonest species o Macroglossum; it never occurs in large numbers but I record it more frequently than any other species. It is highly variable, in particular the white band across the forewing varies both in width and length - at times being completely absent

Macroglossum micacea - another small species, smaller than dohertyi. It is a scarce visitor to the trap

Macroglossum nubilum - the largest of the Macroglossum that I catch, but another scarce species with only two individuals seen

Macroglossum rectans - anpther small species, almost a smaller version of hirundo. I have only caught a handful of individuals of this species

Macroglossum vacillans - the smallest and scarcest of the Macroglossum that I catch

Meganoton rufescens - by far the largest species that I catch with a wingspan of between eigth and ten inches!

Nephele subvaria - a scarce and very variable species

Psilogramma menephron - there are eight species of Psilogramma in Australia all of which are exceedingly variable and similar. This i the commonest of the two species that I catch - it is another large species with a wingspan of six to eight inches

Psilogramma papuensis - the second species of Psilogramma that I catch; another variable species but in general is smaller than menephron

Theretra celata - approx five inch wingspan

Theretra indistincta - aside from its obvious pink antennae a rather plain looking species. Interestingly I  have caught two individual that do not have pink antennae and having discussed this with one of the foreost experts in Sphingidae we are wondering if this would be a new species rather than an odd form of indistincta - waiting to catch a few more and retain them before sending them to him in Paris

Theretra latreilli - one of two virtually identical species of Theretra that I catch; the other being tryoni which is separable only when the species is in the hand

Theretra margarita - another small species with a wingspan of three inches; there are two very similar species separated by the number of white lines on the abdomen - this has only one

Theretra nessus - the largest of the Theretra species with a wingspan of five to six inches. A common visitor to the trap sometimes in reasonable numbers (peak of eight in a night)

Theretra oldenlandiae - imilar to margarite but has two white lines on its abdomen. this is a common species at the trap sometimes as many as twenty a night

Theretra silhetensis - another small species (wing spand two to three inches) and one that can occur in good numbers with a peak of over thirty individuals

Theretra turneri - a scarce visitor to that trap, I have only caught eight individuals of this species

Sharks...

On Saturday we all went over to Newell Beach to have lunch with Angie (Tish's boss) and her family. Before lunch we all went fishing, a very lazy version of fishing requiring nothing more than wandering across the rod and casting four lines off shore to see what we could catch.

The rods are just to the right of Hamish!
It started excellently with a catch almost before Adam had finished casting...our first Shark...



This is one of the Shovel-Nosed Shark complex - not sure which one. More of a Ray than a shark and as such has no real teeth.
That unfortunately was also the last shark we caught  - in fact we caught nothing else until this Catfish spp appeared just as we were going...


I suspect we shall do this again as everyone including Xanthe seemed to enjoy the experience
The clouds from the beach were spectacular .....the photographs less so....

Dragons...

I find Dragonflies a real pain when they come to the moth trap and as such I tend to take a couple of quick photos, catch them and relocate them as far away from the light as is possible. My knowledge of the Australian fauna is very poor although there is an excellent guide that covers all 340+spp. The majority that I photograph are unknown to me but I usually that is just because I have not looked at them before. Sometimes though this is not the case and a potential goodie slips through my fingers!
This is male is a case in point...


I had absolutely no idea what it was but assumed that was just because I don't know my Aussie Dragons, this it turns out is not the case as via a group on Facebook my photo has got back to the researcher at the Australian National Museum who did literally write the book on them and it turns out that it is almost certainly a new species to science as it does not match any known Australian spp - unfortunately a specimen is required and I don't retain Dragonflies......

The Wet

Well last weekend it certainly rained here...it rained, and rained , and rained , and rained, and rained and rai.....you get the picture. Apparently around Cairns there was in excess of 1500mm of rain  that is 1.5m  or 4 foot 9 inches in old money! Whilst I dont think we had that amount Mossman and Port Douglas were cut off for a while with the Foxton Bridge flooded and closed (on road north to Daintree) and the Captain Cook Highway at Craiglie cut off...
This is the creek on the back route into Mossman from home



Not that we could get to the creek from the house anyway as the road just past the winery was slightly wet as well...




But we could get closer from the Mossman side which is where I took this video from...


The road to the creek from Mossman side had some water as well but not as much
