A Sunday morning Butterfly Chase

08 July 2018

     Although a birder first, foremost and always, there is not a single aspect of the natural world that fails to capture my interest. I have different levels of proficiency (or in some cases a decided lack thereof) of various taxa.
     One of the most colourful additions to the summer landscape, especially when the birds are preoccupied with raising young, is a wide range of butterfly species. In addition there are some interesting diurnal moths and I have even been dabbling in nocturnal moths under the expert tutelage of my good friend, Ross Dickson. If you have ever felt you had sinister tendencies of incipient masochism, sitting out in the dark watching moths crawling over a lighted sheet, in a mind-boggling range of diversity, colour, shape and form, will cause them to be front and centre! And that doesn't even take into account the lack of sleep.
     In any event, it occurred to me a while ago that many people I see with a butterfly net have not the slightest idea how to use it properly. They charge around like Don Quixote tilting at some illusory windmill, smacking the ground, flattening the grass, uttering the unseemly curses of a drunken sailor, and coming up empty-handed - or should that be empty-netted?
     With this in mind I thought it would be a good idea to have a proper training session so that budding lepidopterists would learn how to wield a net correctly, sweep with grace and efficiency to capture their quarry, extract it from the net swiftly and cleanly in a collecting vial, take whatever photographs they need, and release the papillon unharmed.
     Owen Lucas, of the rare Charitable Research Reserve, as fine a net professional as one could wish to find, agreed to come and conduct a tutorial.
     People gathered round with great interest.


     Like a magician on a stage, Owen was in short order explaining technique.


     It did not take everyone long to get the idea and we set off on a walk to capture some butterflies. New skills were on display, strategies were developed, and stealth became a new art; but I must say, with a certain level of vicarious pride, that Miriam was the undisputed champion. Hers was a performance worthy of a prima ballerina in the Bolshoi Ballet. In total we captured about fourteen species, much to everyone's delight.


      As a bonus for the eager adventurers we introduced them to the wonderful world of caterpillars. A couple of people had already raised Monarchs indoors so there was the added excitement of seeing the varied forms and colours of the larvae of other species.
     Here is the colourful child of a Black Swallowtail (Papilio polyxenes).


     And how grand is the caterpillar of a White-marked Tussock Moth (Orgyia leucostigma)?



     Jeff Grant, a local teenager from St. Agatha is keenly interested in butterflies and moths and has been raising Cecropia Moths (Hyalophora cecropia) by placing their eggs on appropriate host plants and protecting them by means of a mesh sleeve. Jeff kindly opened up one of the sleeves to show everyone the grandeur of a Cecropia caterpillar - and even provided a little discourse on the life cycle of this stunning moth.


     The caterpillar of an Eastern Tiger Swallowtail (Papilio glaucous), in a late instar with its false eye spots is perhaps one of the most appealing of all, and we were lucky to see one such example along with a little brother (perhaps second instar) on the same leaf.



     We were not quite as happy to find many Gypsy Moth (Lymantria dispar) caterpillars. This species is truly destructive in our eastern hardwood forests and is an invasive species in any event.


     Some had already cocooned.


     The weather was quite beautiful, a perfect day in fact for what we wanted to do. And just in case I had withdrawal pangs from not dealing with birds, Barn Swallows (Hirundo rustica) displayed their aerial superiority as they hawked for insects and a male Eastern Bluebird (Sialia sialis) perched on a nest box where his mate is incubating four eggs. Perhaps he even delivered a juicy caterpillar for lunch.

Rock Point Provincial Park

03 August 2016

     Rock Point Provincial Park is situated near Dunnville (Haldimand County), Ontario, on the north shore of Lake Erie. We had not previously visited this park and, having bought an annual pass to our provincial parks this year, we decided to visit it to see what it was like.
     We had asked our friends John and Geraldine Sanderson if they would like to accompany us and they too looked forward to visiting a park previously unknown to them. We picked them up at 08:00 and set off together for the day's adventure.
     Once inside the park we found an area by the lake that seemed to hold the promise of good birding - and we were not disappointed. Perhaps most impressive was the sheer number of American Yellow Warblers Setophaga aestiva already migrating south, a stark reminder that summer is waning and fall will soon be here.

     We were attracted to the clamour of a fledgling Brown-headed Cowbird Molothrus ater begging incessantly for its surrogate Song Sparrow Melospiza melodia parent to feed it. It seemed that no matter how many insects the dedicated "parent" stuffed into the cowbird's gape it was never enough.

       Many butterflies were found in this area, the most ubiquitous being Cabbage White Pieris rapae.

     We have not seen many Monarchs Danaus plexippus this year but a few have started to show up here and there, and small numbers of this archetypal species were present in the park.

     Not to be outdone the diminutive Spring Azure Celestrina lucia was often observed flitting from plant to plant, alighting only briefly and often concealed by foliage.

     Actually the whole azure complex has recently undergone taxonomic revision and I believe that the Spring Azure may have been merged with another azure species. Butterflies not being my field of expertise, I am not sure whether the name has been retained or not.

     Eastern Tiger Swallowtail Papilo glaucus, large and majestic, drifted everywhere, always an impressive sight.

     The final butterfly species I was able to photograph was Red-spotted Purple Limenitis arthemis astyanax, a distinctive member of the Nymphalidae.

     There are various species of Katydid and I am not proficient enough to know which species this one is, but it was certainly an interesting looking creature.

     Periodically along the beach small groups of gulls were sighted, both American Herring Gull Larus smithsonianus and Ring-billed Gull Larus delawarensis.

     When we had lunch we were entertained by a family of Barn Swallows Hirundo rustica. The adults were providing a constant stream of food to young birds that looked just about ready to fledge.

     After lunch we returned to the car and drove around the park to explore its different features.






     There were several dead fish on the beach, mostly quite large, and of unknown species. As you can see from the following picture nothing had gone to waste.



     The shoreline at this point was predominantly a limestone shelf with sporadic stands of vegetation.


     This sub adult American Herring Gull had located a dead fish in the water and was enjoying easy pickings.


     This park has a sandy beach for families who come to enjoy the water, but the limestone formations prevail for most of the area, especially in the southeast corner of the park.





     Miriam was able to snap this Spotted Sandpiper Actitis macularius, darting in and out of cover to feed. 


     This park is renowned for its fossil formations dating back to the Devonian period, some 300 million years ago, and it was not hard to find them embedded in the limestone and bedrock.





     We all had a splendid day and we will look forward to visiting this interesting park again, perhaps in different seasons, and getting to know some of its secrets.
