Bugs and Butterflies

Here are two miscellaneous shots from the sort pile.  Both involve some cool creature interaction!

First, two milkweed bugs in love (so to speak)

Small Milkweed Bug (Lygaeus kalmii)















Second, some puddling swallowtails.  This spectacular behaviour in butterflies allows them to acquire salts and minerals that they cannot get in their nectar diet.  (incidentally, this photo also includes bug sex - look towards the back!)

Canadian Tiger Swallowtail (Papilio canadensis)















That's all for now!

More Confusing Critters

Well I got back at the photos today, and it seems the ones I leave till last are the ones that are the trickiest.  This also means they take the most time and energy!  Here are two creatures that forced me to break out the field guides!

The first is a dragonfly - some sort of mosaic darner to be more specific.  After lots of reading and photo-referencing, I'm going to say it's a Shadow Darner, though I would love to be corrected if you know differently!  I do have other photos of the entire insect, if anyone fancies the challenge.  I really do need to get myself a better dragonfly field guide...

Shadow (?) Darner (Aeshna umbrosa)















The second creature of the day is a tiny moth that I can't find in any of the books I have (though as previously mentioned, my library is far from complete).  It's a good-looking creature, but I have no idea what it is!  Photographed in the Guelph Arboretum.

That's all for now!

Random Photos

Well it has definitely been a slow fall for blog posts - I blame that on my real job and a daunting stack of unsorted photos.  I have started to sift through this aforementioned stack, and some of the results can be seen here.

On another note, I am gearing up for some time out of country - a week in the Dominican Republic with the family over Christmas, and the 2.5 month journey to southern Africa that I posted about earlier.  I am hopeful that both will deliver some excellent opportunities for good photos and stories to match.  I am long overdue for a shake-up, and can't wait to get going!

Anyway, on to the photos.  The first is an odd one that has been sitting in my "To Sort" folder for months, mostly because I'm not sure what to do with it for several reasons.  Firstly, I'm unsure of the species, though my educated guess is Sweetflag Spreadwing.  Secondly, the picture also features some mysterious white orbs (on the stem, under the damselfly), and I have no idea what they are.  I have asked a few knowledgeable folks, and they have been stumped as well.  I don't know if they are associated with the damselfly at all, or if it is simply a coincidence that they are together.  If anyone can solve this mystery, please let me know!  Also of note is the cluster of red mites attached to the underside of the spreadwing.

Sweetflag (?) Spreadwing (Lestes forcipatus)















The second shot is another that fell by the wayside because it took more than 10 seconds to identify (and I'm sometimes lazy).  One of several plain, brown butterflies that lives here in southern Ontario, the Northern Pearly-Eye.  Distinguishable - it turns out - from the others by the reduced or absent second (from the front) spot on the forewing, especially noticeable from the underside (because I know you were wondering...)

Northern Pearly-Eye (Enodia anthedon)















This next one was a surprise find and a bit of a mystery.  I was herping in Simcoe County with a couple of friends, and one of them turned over a rock and uncovered this moth.  It certainly appears to be to be a Virgin Tiger Moth, but what I can't reconcile is that the forewing pattern is distinctly pinkish-orange, instead of the usual yellow.  I haven't seen a lot of these moths, so I don't know if this is a normal variation or if it's unusual.  Alternately, it is a different but similar species of which I am unaware.  I don't own a good moth book (necessary future investment) and have not been able to figure this out.  I was able to push the forewing aside, and it did have the red hindwing pattern that I associate with Virgin Tiger Moths (though apparently I was not smart enough to document this photographically).

Virgin (?) Tiger Moth (Grammia virgo)















The last shot for today was a quick grab-shot I took while looking for snakes in Norfolk County.  It was sweltering hot, we were out in a field, and we were skunked for snakes.  This little butterfly landed in front of me and, being unsure of its identity (and knowing I had not photographed one before), I started snapping.  I got three shots before it flew away - two were blurry, so this is now my only photo of an American Copper.

American Copper (Lycaena phlaeas)















Well that's it for today, but it feels good to have made a dent in the pile of photos - hopefully it'll motivate me to do more soon!  I'll also get some details up about the upcoming travel as the preparations progress!

Correction!

Almost caught with my pants down there!  Metaphorically of course.  Fortunately nobody called me on it.  In previous post, the female "Twelve-spotted Skimmer" should read "Common Whitetail".  Will make necessary correction.

Correction!

Hello!

Well, it's happened again - I screwed up.  Rare, I know, but it does occur.  All previously posted photos of Eastern Cottonmouths are in fact Western Cottonmouths (Agkistrodon piscivorus leucostoma).  Please forgive me.

Thank you to an astute observer (you know who you are!) for that correction.

Also, buy a calendar!!  Never mind subliminal advertising, it's straight to the super-liminal for me!  See previous post for details.

Identification Correction

There seem to be a lot of these recently...I wonder why...

Anyway, the Hairstreak sp. that came up two posts ago - I'm going to go with Eastern Tailed Blue (Cupido comyntas).  Any takers?  Hearing no objections, I shall consider it approved.

These are close kin to the Hairstreaks (same family) so I guess I don't feel that bad...

Misidentifications do happen...

Hello!

It has been brought to my attention that I misidentified a certain critter in an earlier blog post.  A shameful misstep - all I can do is pray for forgiveness.  The creature in question is this one:
















I identified this by default as a Green Frog (Lithobates clamitans).  It was found at an urban park that I have been visiting for years.  The park has some ornamental ponds which typically freeze to the bottom in the winter (making it next to impossible for frogs to overwinter), but attract Green Frogs and Leopard Frogs (Lithobates pipiens) throughout the summer.  I never gave it a second thought until an astute observer pointed out to me (with some relish) that I was wrong!

Although it is by no means a pretty example of either species this beast must be a Bullfrog (Lithobates catesbianus), not a Green Frog.  The primary difference lies in the absence of dorsolateral folds - folds of skin that run from behind the eye towards the rump.  Look at the folds on this Green Frog:
















So I suppose mistakes do happen, and I guess I can live with myself.  At least this will make an interesting submission to the Ontario Reptile and Amphibian Atlas.

Odonate ID

Hello,

So I spent 5 minutes reading this evening (yes, I can read) - something I maybe should have endeavoured to do prior to my earlier post.  It's amazing how reading can really teach you things.  It has been good (read challenging) to catch up on some long-forgotten damselflies.

So to that effect, the third "bluet" in my series is actually a Violet Dancer - a damsel that I knew to be a riverine species but found some distance from the nearest river.  I'm quite doubtful of the first "bluet" as well, but I guess I didn't get that far in my reading.  The unknown pruinose (fuzzy) damsel is a Powdered Dancer (I believe).

As usual, if I'm wrong and you'd like to correct me please feel free.  Otherwise I'll never learn :).

Website Updates and ID Trivia

Hello!

I have spent some time with the field guide and updated some labels on the photos in my Costa Rica Gallery (http://www.kylehorner.com/costarica.php).  I have used common names, but can provide latin names upon request for all you taxonomy nerds (if there are any besides me).

If anyone fancies a taxonomic challenge, I have some still-unidentified species.  For each correct ID, I will commend you highly (sorry, no material or financial prizes are available at this time).  Here they are:

Some type of Norops anole...















A nifty butterfly...















A cool damselfly















A wicked caterpillar...















Also, if anyone fancies themselves an expert on Costa Rican spiders, we should talk.  I'd be happy if they could be identified to family.  Check them out in the gallery.

Cheers!
Kyle
