Ladies of spring

The light switch of spring has been thrown.  One day it was cool, and the next it was warm enough for shorts and a t-shirt.  There it has remained, warming the earth and inspiring an explosion of life.

A veritable smorgasbord of insects and arachnids has appeared.  Flies buzz, wasps and bees flit about, beetles emerge, spiders spin and leap and dash, and where just a few weeks ago the days passed with scarcely a single small critter to enjoy, now it’s difficult to know which one to focus on.

But winter’s dearth always gives way to spring’s bounty, something that plants and insects demonstrate with great passion.  And often one of the first things to appear in abundance is the lady beetle.

Standing on the patio the other evening, only a few moments before sunset, a small beetle rushed along the patio fence.  I ran inside, grabbed the camera, then returned to snap a picture or two.  By that time the little lady had scampered between the slats where it no doubt wanted to grab some rest for the night.

So I was mocked by this ashy gray lady beetle (a.k.a. ash gray lady beetle; Olla v-nigrum) who showed me nothing but buttocks.  I stood patiently hoping the hideout was temporary, but alas the insect nodded off to sleep and stayed put, so a gray moon was all I had to show for the encounter.

Finding this seven-spotted ladybug (a.k.a. seven-spotted ladybird; Coccinella septempunctata) larva came as no surprise.  These beetles start mating and multiplying the moment it’s warm enough outside.

(No, it’s not missing any legs.  The one good photo I took happened to have one leg curled underneath the larva as it changed direction.)

And an adult seven-spotted ladybug (a.k.a. seven-spotted ladybird; Coccinella septempunctata) soaking up sunshine atop a dandelion.  Days may be warm, but nights are still cool enough to require a recharge of heat each morning.  Though that’s changing quickly as quite soon nights will be comfortable and days will be unbearably hot.

As these two multicolored Asian lady beetles (Harmonia axyridis) show, the season is never too early for making babies.  If it’s warm enough to move about, it’s warm enough to mate and multiply.

This multicolored Asian lady beetle (Harmonia axyridis) landed on my shirt as I stood on the patio enjoying warm sunshine one afternoon.  It’s unwise for anything small to enter the house since The Kids take seriously their duty to hunt down and dispatch invaders.  So I plucked the little beetle from my shirt in order to place it on the patio fence.

Then, for the first time in my 40 years, a lady beetle bit me.  The ungrateful invader apparently found the relocation disagreeable and decided to nibble on me as repayment for the move.  The experience was interesting but not painful.  The biggest shock was that it took four decades to experience it given how much time I spend in nature and how often I have run-ins with fauna.

Despite the transgression, I put the beetle on the fence with gentle care so it could go on with its day.  Though I did scold it briefly and warn it that others might not be so forgiving.

Walking across the bridge over Dixon Branch, a spark of color on the concrete railing gave me a moment of pause.  This convergent ladybird beetle (a.k.a. convergent lady beetle or convergent ladybug; Hippodamia convergens) faced into the rising sun to gather warmth.

The number of lady beetle species at White Rock Lake is high, but unfortunately a great many of the numerous examples are from introduced species.  Finding endemics like the ashy gray or the convergent tends to be like finding a needle in a stack of needles.  Nevertheless, they can be found if one looks carefully enough.

We’re not taking it anymore

Before we received a double-whammy of snow last week with two significant storms, it appeared on March 1 that spring had not only gotten its foot in the door, but that it had shoved its way into the room and intended to kick winter out with much fervor.

In response to the warmth, White Rock Lake brought to light its magnificent insect collection.  They came out in force, as though the whole of the population unanimously declared “We’re not taking it anymore!” in response to winter’s attempts to stick around.

Bear in mind a large number of wasps occupied the area.  Ants and wasps concern me more than bees, for the latter are generally docile unless protecting a hive with honey and/or young, or when directly provoked.  On the other hand, the former two bring with them an air of unpredictability and dour temperament that lead me to exercise respectful caution while in their midst.

I point that out because, given the acute nature of my allergy to their stings (ants and wasps especially), I was forced to keep my distance when photographing many of these insects.  It’s not that I’m unwilling to let them near me; it’s just that I have no interest in pushing my luck when it seems entirely unnecessary.  Hospitalization is something I try to avoid…

I strolled along the floodplain adjacent to Dixon Branch.  The large swathe of land had miraculously given birth—almost overnight—to a field of wildflowers.  Some I recognized and some I didn’t, but even from a distance I could see the area was abuzz with insects of all shapes, sizes, and colors.

A spotted cucumber beetles (Diabrotica undecimpunctata) on top of a common dandelion (Taraxacum officinale) (20080301_02410)

Nearly every common dandelion (Taraxacum officinale) I saw had one of these little green beetles on or near it.  Ubiquitous fails to describe their collective presence.  Any flower devoid of their telltale spots soon trumpeted the arrival of a visitor either flitting in from another flower or crawling out from under the petals.

Only later did I identify them as spotted cucumber beetles (Diabrotica undecimpunctata).  The specific subspecies still eludes me, though, yet I continue my efforts to learn that information.

Almost as numerous as the beetles, western honey bees (a.k.a. European honey bees; Apis mellifera) filled the air with buzzing, a fog of busy wings collecting pollen and scurrying about the order of the day: prepare the hive for this season’s brood.

Again, I have not identified the exact subspecies of the bees.  It’s quite possible I photographed more than one; it’s equally plausible that they are all the same.  More work is needed to pin down an exact identification.

On a day when so much activity takes place, traffic jams are abundant.  More than once I witnessed a bee or wasp landing on an already occupied flower.  In this case, the honey bee barged in on the cucumber beetle’s territory.

Neither seemed to mind the other too much.  Well, except when the beetle found itself trampled underfoot by the bee.  Only then did it hurry out of the way of the much larger insect.  Aside from those fender benders (which bothered the beetles more than they did the bees), these insects went about their business without too much involvement with each other, and at no time did a scuffle break out after a collision.

This photo surprised me because I never saw the fly behind the dandelion until I processed the images later.  Perfectly camouflaged amongst the brown winter grass, it remained perfectly still as I invaded its personal space.  My intent?  To photograph another insect on the flower.  The result?  The camera actually focused beyond the petals and found what I did not see.

While I can’t be sure of the species at this time, I believe this is a crane fly of some sort.  I need to look more closely at the picture (the only one I have of this critter) to see if I can come up with a final determination as to its classification.  (See update at the end of this post.)

A close-up of a spotted cucumber beetle (Diabrotica undecimpunctata) on top of a common dandelion (Taraxacum officinale) (20080301_02428)

Most of the cucumber beetles fled the moment I encroached upon their territory (meaning whatever flower upon which they had staked a claim).  Sometimes they skirted the open petals and hid beneath the bloom; sometimes they hurried off the pollen machine and disappeared into the grass; and sometimes they took flight and vanished amidst a writhing sea of insects flying throughout the area.

This one did none of those things.  Despite my proximity to it, not once did it flinch, even when I accidentally bumped the flower with the camera lens.  It treated me with disinterest at best.  I appreciated that as it gave me a chance to get some better photos.

A close-up of a seven-spotted ladybird beetle (Coccinella septempunctata) as it climbs up a blade of grass (20080301_02444)

While I knelt in the grass peering at that bug, I realized the ground beneath me teemed with life I had yet to notice.  A variety of lady beetles (a.k.a. ladybugs or ladybird beetles) carried on with their spring affairs in a jungle no higher than my ankles.  A whole other world existed down there, one hidden from those who failed to stop and look.

That seven-spotted ladybird beetle (Coccinella septempunctata) gave me quite a bit of exercise as I chased it about trying to get at least one presentable image.  But these insects were busy and had no time for my shenanigans.  They appeared and disappeared in a flurry of comings and goings, and taking photographs of them proved difficult as they never sat still.  At all.

Why?

Did I mention they were busy?  Yes, busy looking for mates and doing what comes next.  While I do apologize to the younger members of our audience for the unexpected insect porn, seeing this mating pair of convergent ladybird beetles (Hippodamia convergens) demonstrates why they had no time to stop and pose for my camera.  If indeed spring had sprung, their focus seemed clear: procreate at all costs.

Oh, they never stopped moving even when caught in such compromising positions.  The larger female dragged the pair up and down, over and under, and every which way she could, so even the business of being busy didn’t stop them from playing hard to get—photographically speaking.

Another interesting thing about that image—other than the insects being out of focus—is the scale made evident by the dandelion seed at which the camera actually took aim.  It dangled from a small blade of grass above and behind the beetles.  Despite that, it appears gigantic compared to them.  Compared to both of them combined even.

And finally, note that both are being held up by a single blade of St. Augustine grass (a.k.a. carpetgrass; Stenotaphrum secundatum).  You really must appreciate how small these insects are despite their enormous usefulness in controlling other pests.

[Update] The insect in the fourth photo is actually a stilt bug from the family Berytidae.  The precise species escapes me for now.
