Wide Angle Macro Photography?

The WGNSS Photography Nature Group met at Cuivre River State Park on Saturday the 2nd in hopes to find members of Limacodidae (slug moths). Perplexing to me, we struck out in the same time and place I found them in numbers and diversity a year ago.

It was still a good time. We found a number of other macro subjects and explored a couple of new places. I also got to give a first spin to my new lens. A wide-angle macro – the Laowa 15mm f/4 Wide Angle Macro. A rather new lens design and one with a pretty steep learning curve, these photos are really just practice. With time and strategy, I think I can get better at this.

Two areas to focus on in improving with this lens:

1) Getting a better handle on exposing for the environment (background) while getting the right amount of light from the flash to properly expose the foreground macro subject. I think this should be easier to predict with practice. I’m not at all sure that I can ever get it on a first try.
2) Figuring out how much dof is just right. Sometimes getting more detail in the background will be desirable. Other times, it is best to blur it out to bring focus on the primary subject.

This is a funnel web or grass spider (Agelenopsis spp.) that we found protecting her egg sack on the leaf of poison ivy (Toxicodendron radicans). She will likely guard the eggs here until the winter takes her.

One of the nice finds of the day was this Black-waved Flannel Moth (Megalopygidae – Lagoa crispata (4644)). One of the key features of this lens is being able to focus close enough to the primary subject for macro-level detail while capturing so much more in the subject’s environment. In this case, I tried to give the perspective of what it may be like for the bug when being discovered by entomologists or nature photographers. Pictured left to right are WGNSS members Rich Thoma, Dave Seidensticker and Casey Galvin.

After the group disbanded at Cuivre River SP, Miguel Acosta and I decided to visit and explore Little Lost Creek Conservation Area near Warrenton. We hiked about 6 miles and I camped there the following evening. I took a quick photo hike in the morning and found these two Brown Stink Bugs (Pentatomidae – Euschistus servus) in copulation. They didn’t like that lens being so close and kept moving to the opposite side of the boneset (Eupatorium) blooms.

Council Bluff Lake Insects – Part One

Elderberry Borer – Cerambycidae – Desmocerus palliatus

Members of WGNSS Entomology and Nature Photography Groups met on June 24th, 2017 to see what interesting insects could be found.  In this post I am sharing a few of the more interesting that I was able to get photographs of during the day.  The find of the day had to be the Cerambycid pictured above that was, by no surprise, found by Ted MacRae.

Delta Flower Scarab

We found that blooms were a great way to find beetles.  It is easy to see how the delta flower scarab (Trigonopeltastes delta) got its name.

Flower Longhorn

Cerambicids like this flower longhorn can readily be found on blooms.

Banded Netwing

The banded netwing beetle (Calopteron reticulatum) are easy to find, often located in the open atop vegetation.  They rely on aposematic coloration to advertise that they carry aboard chemical compounds that make them a distasteful meal.

Agapostemon sp

The Hymenoptera were well represented on blooms of wild hydrangea (Hydrangea arborescens), Queen Ann’s lace (Daucus carota) and as pictured above, fragrant sumac (Rhus aromatica).  I find the native bees to be tricky to identify by photographs, but I believe this can be placed in the genus  Agopostemon.  These bees nest in the ground and to promote them, leave patches of soil exposed somewhere in your yard.

Cuckoo-leaf-cutter Bee – Megachilidae – Coelioxys sp

This cleptoparasitic Coelioxys exclusively parasitizes the nests of bees in the Megachile genus.

Scaly Bee Fly – Bombyliidae – Lepidophora lepidocera

Besides being a bizarre little pollinator, this scaly bee fly is a cleptoparasite of cabronid wasps.

Double-toothed Prominent – Notodontidae – Nerice bidentata

Not to leave out the Leps, this double-toothed prominent moth larvae was found.  These guys have developed very effective camouflage that allows them to blend in and resemble the toothed, wavy margins of their elm (Ulmus) host plants.

 

 

 

 

 

Northern Fence Lizard

Northern Fence Lizard

During our search for insects at Council Bluff Lake, the WGNSS Nature Photography Group stumbled upon this cooperative and gravid female northern fence lizard (Sceloporus undulatus hyacinthus).  She allowed our close inspection as she attempted to bask and warm herself on a rock.

It’s Officially Spring!

Blackburnian Warbler, Carondelet Park, May 2017

Along with finding the typical rarities that everyone looks for during spring migration, I will not count spring as arriving until I lay eyes on a male Blackburnian Warbler.  This past Saturday, not only did Miguel and I find my prize at Carondelet Park, but I got my best photos to date of this tree-top dwelling, piece of greased lighting.

Blackburnian Warbler, Carondelet Park, May 2017

With a throat this bright and luminous, a song that is so high-pitch that dogs aren’t safe for blocks and a never resting habit, more than one birder has assumed these guys must be powered by a battery.  Seriously, there’s a reason these guys eat all day long.  They have to!

Well, hopefully I might have another before the season has completed springing.  If not, I’ll always have something to look forward to next year.

Species #282 – Veery

Veery, Tower Grove Park, St. Louis Missouri

Miguel Acosta and I decided, along with many other birders and bird photographers, to head to Tower Grove Park to check out the latest migrant action.  Although the migrant songbirds were overall pretty disappointing, the morning was surely not a bust for me as I was able to photograph my 282nd species in Missouri and contiguous states – the Veery.

Veer!

This guy’s polyphonic vocalizations have been among my favorite of bird songs for a long time.  On the rare occasion these guys sound off during migration, the songs come from a deep thicket and I rarely get to lay eyes on the songster.  The beauty of migrant traps like Tower Grove and Carondelet Park in the heart of the city is being able to get great looks at these northern nesters.

Pollinators of Spicebush

Sawfly – Tenthredinidae – Dolerus neoagcistus

With some extra nature time last week, I hit the trails at Shaw Nature Reserve hoping to get some shots of Claytonia virginica (spring beauty) being visited by its pollinators – particularly the small solitary Halactid bees.  The problem I had on this day is that these bees don’t typically like to be very active on cloudy, grey days.  There were a few flies visiting the spring ephemerals, but they were much to flighty to bother with.  So, I decided to give some attention to the Lindera benzoin (spicebush) that were blooming in abundance along the river bottom trails.  My goal then became to document the pollinators that visit this early-blooming bush.

Sawfly – Tenthredinidae – Dolerus neoagcistus

One of the more obvious of these pollinators that I found was this sawfly.  This is my best guess on identification.  This sawfly was quite small and by the looks of it, is quite an efficient pollinator.

Sawfly – Tenthredinidae – Dolerus neoagcistus

Probably the most abundant pollinator I came across were these Tachinid flies (again, flies are difficult and I could be wrong).

Tachinid Fly?

The hair-like setae that probably serve to aid the fly in responding to changing air pressures also serve as nice holders to move pollen from flower to flower.

Tachinid Fly?

I also found a number of multicolored asian lady beetles (Harmonia axyridis).  Typically predators of aphids, these beetles are also known to feed on pollen.  This is what I figure was going on in the image below.  Since there are probably few aphids to be found during the early spring, with few leaves being available, pollen is the next best protein source.  I suppose there could be aphids to be found hiding within the flowers, but did not inspect closely enough.

Multicolored Asian Lady Beetle – Coccinellidae – Harmonia axyridis

Probably my favorite find of the day were several flies of the family Empididae.  These are fascinating flies that are primarily predatory, but a few taxa will visit flowers to feed on nectar or pollen.

Dagger fly – Empididae – Empis or Hilara genus

Within this family are at least a few where the females will not hunt themselves, instead relying on a “nuptial gift” of a prey item from a male.  Males of some species will wrap their gift in a silk wrapper.  In these taxa the sex roles will often be reversed – the females courting the males to get these gifts and the opportunity to mate.  In at least one species, the females will inflate themselves grossly with air to give herself the appearance of being bound with eggs and fecund, to trick the male into thinking she is a prime candidate to provide his gift and have the opportunity to mate with.

Dagger fly – Empididae – Empis or Hilara genus

At least one species has taken this system a step further.  The males no longer provide a prey wrapped in its decorative covering, but simply provide the silken covering, or balloon, giving them the name “balloon flies”.  The photo below provides a good look at the dagger-like moth parts that give these guys another of their common names.  Another overlooked beneficial fly.  Not only do these guys prey on mosquitoes and other potential pest insect species, but their larvae are also predatory, feeding on insects in the soil and leaf litter.

Dagger fly – Empididae – Empis or Hilara genus

I’ll leave you with one final image.  This one isn’t a pollinator of the spicebush, but potentially feeds on its leaves in summer.  What I believe this to be is a (Camptonotus carolinensis) Carolina leaf roller that was parasitized by one of the “zombie fungi”, potentially Cordyceps sometime last summer or early fall.  This poor cricket was infected with this fungi that took control of its “mind”, forcing it it to climb high up on a branch of the spicebush.  Once there, the fungi used the cricket’s resources to fruit and spread its spores from this higher location in order to reinfect others.
