Flower Hunters

When it comes to carnivorous invertebrates, I've always had a soft spot for dragonflies (as regular blog visitors will recognize).  But perhaps coming a close second, at least from a photographer's perspective, is the unrelated group of critters that I'll call flower predators.  These crafty creatures disguise themselves as flower parts and prey upon unsuspecting pollinators, taking cunning advantage of nature's elaborate system for insect attraction.

Last year I posted the photo below of a Goldenrod Crab Spider preying on a European Honey Bee (albeit not on Goldenrod).  These little spiders are favourites of mine, and can actually change their colour from white to yellow in order to match their background.

A few days ago I had the good luck to stumble upon a completely different flower predator, also munching (or rather sucking) on a meal of bee.  Ambush bugs belong to a group of insects that entomologists confusingly call "True Bugs".  The group is distinguished by its mouthparts, which function as a bi-directional, hypodermic needle.  They impale their prey (which may be animal or plant, depending on the species), inject a digestive enzyme then suck out the resultant goop.

The ambush bugs get their name from their hunting strategy, which as you may now have guessed, involves sitting in wait, camouflaged on a flower.  They then use their raptorial forelimbs to snare their prey, then quickly set about the act of pre-digestion.

I am admittedly poorly-acquainted with our native bees, so while I have some inklings, I will withhold any embarrassing guess at the identity of the unfortunate victim.

And another angle on the action:
















Keep an eye out for upside-down bees as you smell the flowers - they always point you to something good!

Magnificent Moths!

I had the good fortune to join a small crew of lovely folks at the Guelph Arboretum a few nights ago for some spirited mothing.  I was amazed to learn that over 600 moth species have been observed at The Arboretum alone, and when we delved into the identification of them I was instantly hooked by the new challenge!

For the uninitiated, mothing involves the attracting of nocturnal moths using UV lights, moth bait (comprised of rotting fruit and beer) and sometimes, though not on this occasion, pheromones.  Attracting them is easy - figuring out what they are is a whole different story!

Many of the moths we attracted were tiny, but there was a fair number of big ones too (definitely more interesting to a neophyte like me, and easier to photograph too!).  I grabbed a handful of photos - here is a small selection:

The Herald (Scoliopteryx libatrix) - moths have great names!















Pale Beauty (Campaea perlata) - a common sight by the porch light.






















Pink-spotted Dart (Pseudohermonassa bicarnea) - I think, anyway...















Baltimore Snout (Hypena baltimoralis) - an appropriate moniker.

The Bride (Catocala neogama) - big and beautiful, enjoying some rotted fruit and beer.















In between checking for adult moths, we searched for some young guns:

That's all for now!

The New Brunswick Python Story

I had intended to wait until all of the facts were clear to address the New Brunswick python situation, but it is becoming increasingly clear that this may never be the case.  What follows below is my opinion, and I apologize if it offends.

There’s no sense beating around the bush: the New Brunswick python story is a tragic situation.  If the case is as presented in the media, it speaks to great negligence on the part of the snake’s owner.  If it’s not, perhaps it speaks to something even worse. 

While many have rushed to conclusions, in my mind there is still a great deal of room for doubt here.  The story as presented is, to put it mildly, completely bizarre.  As a reptile biologist, educator, hobbyist and one-time keeper of giant snakes (in a zoo setting) the details of the story are difficult for me to fathom, and there are many unanswered questions.  Why would this snake, or any snake, constrict and kill something it did not then try to eat?  Why not one boy, but two?  Why has there been no mention of the bite marks, broken bones or extensive bruising that would accompany constriction by a large python?  How did a 45kg animal falling from the ceiling and violently constricting two boys not draw the attention of the other people in the house?  How did the killing of the first boy not wake the second?  And so on.

When reading the stories and watching the news, I think it is important to keep in mind the great deal of conjecture, potential misinformation and missing information involved, and to keep an open mind for now.  Regardless of the outcome though, there is no doubt that this story has affected the way people look at snakes.  Angry mobs are calling for the closure of zoos, a war on exotic pets and the banishment of those who keep them.

Making matters worse is the fact that the reptile community does – like many communities – play host to its fair share of sketchy characters.  And that the community, as a whole, doesn’t have a history of responding to controversy in the most professional, upstanding and responsible way.  In the last week I have seen not one but two individuals strolling around downtown with snakes on their arms, an apparent act of solidarity that serves only to alarm, frighten and generally worsen public perception.

While I am content to treat the New Brunswick situation as an incredibly isolated incident (almost certainly unique in Canadian history) and to accept the evidence as it comes, I worry about what this means for the world that, in spite of its inadequacies, I have come to love.  Reptile zoos, and even the reptile pet trade, serve a vital purpose to educate and improve attitudes about the most imperiled of Canada’s creatures.

I will be the first to agree that giant snakes, like the African Rock Python, should not be allowed as house pets under any condition.  Their keeping should be limited to qualified zoos with properly trained staff and the appropriate safety measures.  By-laws already address this in most municipalities.  But there is a host of species that make excellent educational ambassadors, and even good pets.

Take, for example, the humble Corn Snake.  Captive bred for over 70 years, these peaceable snakes do not exceed 2m in length and are incapable of harming anything larger than a rat.  Western Hognose Snakes are short and fat, and make their living eating toads and salamanders.  Rosy Boas could easily fit their entire body on top of the head of one of their larger, better-known cousins, and can be kept for their entire lives in a Rubbermaid sweaterbox.

Close-up experiences with these and other responsibly-kept species help kids (and adults) overcome fears, replace misinformation with knowledge, co-exist with their local fauna and contribute to reptile conservation.  They are the kind of experiences that put me where I am today, teaching others about nature and fighting for conservation through education and personal connection.  For every shady snake guy, there is a host of wonderful, responsible people providing lasting experiences in a safe manner.


Whatever the verdict in the New Brunswick case, I hope that when the dust settles we can all take a step back and see reason.  When (or if) the complete story comes to light, the blame will fall squarely on the shoulders of a person, not an animal or a community.  We should support reasonable rules and regulations for zoos and pet owners, and hold them appropriately accountable, but we must realize the vital purpose they serve.  Protection, both of ourselves and our wild neighbours, will be achieved not through fist-shaking, finger-pointing and angry letters, but through tolerance, understanding and cooperation.

Boring Odes?

I am playing catch-up as usual, but managing to get a few shots edited.  On my recent foray to shield country, I picked up a few photo-lifer odes.  Exciting for me, but I suspect that to many, they are some of the less charismatic dragons and damsels out there.  Nevertheless, I like 'em, so here they are!

If any odonate experts out there see issues with my identifications, let me know!  These freakin' things are hard!!

Ashy Clubtail (Gomphus lividus)















Lancet Clubtail (Gomphus exilis)















Stream Bluet (Enallagma exsulans) - and a lot of mites!















Hagen's Bluet (Enallagma hageni)















They may be the sparrows of the odonate world...

Sometimes things just work...

Haven't posted on the blog in forever - it's been a busy summer!  I'm way behind (as usual) in photo editing, but figured I'd better put one up here before Blogger closes my account :).

Here's a recent shot that I was really pleased with...not because it's a fantastic photo, but because of the circumstances surrounding it.  The small, brown, forest butterflies (Wood-Nymph, Eyed Brown, Pearly-Eye, etc) are always challenging subjects.  They are fast and flighty, rarely land (and even more rarely in opportune photographic locations) and tend to hang out in dark places.

When hiking recently in Silent Lake Provincial Park I spotted an Eyed Brown landing on a tree nearby, about 8 feet off the ground.  The canopy was very heavy and the day was overcast, so the conditions were really dark.  Using the flash meant that I would likely only get one shot, as the creature would likely take off in response to the burst of light.  So I took a good guess at the exposure, prepared the flash and crept towards the tree.  I leaned against the trunk, pointed the lens straight up, focused and fired.  Sure enough, the butterfly took off and I was left waiting till I got home to see if it worked.

Turned out not too shabby :).
