Insect Extravaganza
This September and the first week of
October, 2008 I spent about three weeks
watching several burroweeds, Isocoma tenuisecta, in my back yard
while they bloomed.
(I assumed they were burroweeds. I didn't plant them although, over the
years, I have
pruned them to remove spent blooms and improve their appearance.) I was
first
attracted by the number of bees visiting the blooms. As I watched
the bees more closely I began to notice quite a few different kinds of flying
insects and when I took off my glasses, got down on one knee, and really
took a close look at one of the plants, I was surprised by all the insect
activity. Far more variety than I'd ever
encountered in one place.
Over the next couple of weeks I tried
to stop by the burroweeds in the morning and evening to see what was
happening in the insect world. Pretty soon I carried a camera with every
visit to the plants and eventually I included a small pillow so I could get
down on both knees to get to the insects' level and get that up close and
personal contact.
At first I noticed the
predominate
flying insects including bees, flies, moths and butterflies. Then I began to
notice some of the predators that were considerably more stealthy, limiting their
movement, while they waited for their prey to get near enough that they
could strike. This included the spiders, praying mantis, and
assassin bugs. I figured the large praying mantis (there were at least five,
possibly more) were the top of the food chain although they would certainly
be susceptible to the lizards roaming under the shrubs and any birds that might find
them.
Surprisingly the only mantis I saw succumb was one that was eaten from
the inside out. Some sort of insect that produced small maggots
managed to deposit eggs inside the mantis and the young eventually ate their
way out. Somewhat gruesome for sure, but also interesting to encounter in
the garden.

This mantis moved
to a Blue Palo Verde tree trunk and sat there for two or three days
until the maggots in its abdomen ate their way out. |

After the parasites
finished feeding this was all that was left of the mantis. |

I must admit I became fascinated
by all the insect activity on the burroweeds and probably spent far more
time than I should observing, taking pictures and trying to figure out what
many of the insects might be. I had two field guides from the National
Audubon Society which were helpful for many of the insects. I also did lots
of image searches on the internet, sometimes finding what I looked for,
other times, too much information added to my bug confusion.
I certainly didn't catch every
type of bug that visited the burroweeds in pictures. Some were too small and
I couldn't get close enough with the camera lens I used. Some were too quick
and would come and go before I could capture a picture. I know I missed one
metalmark butterfly I'd never seen before and I had a Sphinx moth that
wouldn't sit still. Others I just didn't see. Some of the small spiders were
very good at hiding. One flying insect that I waited to land got snapped
from the air by a mantis and I never did get a picture.
I also discovered my macro
photography skills were not what they could be. I had an awful lot of bad,
out of focus and no bug in the frame pictures. And on windy days I was lucky
to get any useable pictures at all.
It's pretty obvious there are
a lot of bugs in the garden. Some are beneficial, others detrimental. The
good with the bad. You have to be willing to look for them and at
the same time appreciate them for their role in the ecosystem whether they
are permanent residents or only passing through.
Sure, I'm still at war with the
mealy bugs in my greenhouse, the aphids, and squash vine borers in my
vegetable garden. I'm wary of black widow spiders, scorpions and centipedes
when I come across them and still cringe when I
find a blood sucking conenose in my bed. But after my couple of weeks with
the insects pictured below I think I can appreciate them quite a bit more.
And you can be sure I'll be taking a close look at my blooming burroweeds
next September to see what's visiting. (2008)

 |
 |
 |
Reakirt's Blue,
Hemiargus isola
These small butterflies were regular visitors to the burroweed. |
Palmer's Metalmark,
Apodemia palmeria
Besides the various bees these Metalmark butterflies seemed to
visit daily while the burroweed flowered. |
Metalmark butterfly. Only
saw one of these little brown metalmarks during the last week of
September. |
Great Purple
Hairstreak, Atlides halesus
Like the Gray Hairstreak, the small
butterfly moves the ends of the wings so it's difficult to
distinguish which is the head end. |
 |
 |
 |
 |
| Gray
Hairstreak, Strymon melinus
Clever little butterfly moves the
wing appendages emulating the insect's antenna so you have
trouble deciding which end is up. |
Snout.
The long nose of the butterfly makes
it easily identifiable The most common to visit the burroweed
flowers was the American Snout, Libytheana carinenta. |
Queen
butterfly, Danaus gilippus |
Progressive Bee
fly. Another large fly that
was easy to spot and photograph. |
 |
 |
 |
 |
| Honey bee.
Bees, lots of different types of
bees, worked for the pollen on the flower heads.
|
Green
Metallic bee. A common site
on the flower heads of the burroweed. |
Bee
fly. This large fly with
the clear wing tips was pretty obvious when he showed up on the
flower heads. |
Bee fly.
Big bee fly with intricate design in
the wings. |
 |
 |
 |
 |
| Possibly
a Tachinid fly. Looks like
his hairs are standing on end. |
Green
Bottle fly. |
Lacewing. Didn't see many
lacewing. Did notice their single eggs on fine filaments on some
of the blooms. |
Unidentified moth.
Notice the fin the wings make when
closed. |
 |
 |
 |
 |
| Plume
moth. Good thing these
moths are small, otherwise they might be kind of frightening.
Could you imagine one the size of a pigeon flying at you. Might
make for a good horror movie. |
Possibly a paper wasp. Two
or three different kinds of wasps visited the plants |
Either
a Steel-blue Cricket Hunter wasp or a Blue Mud Dauber. |
Thread-waisted
wasp. These wasps were
fairly common and quite active on the plants for a few days. |
 |
 |
 |
 |
| Potter
or Mason wasp. You don't
realize how many different colored wasps are present until you
start photographing them and can compare their markings side by
side. |
Spotted
Cucumber beetle, Diabrotica undecimpunctata |
Mantis
and a bee snack. I was
watching this praying mantis as the bee flew past. In a split
second the mantis captured it. There's a third insect in this
photo I didn't notice at the time of the photograph. Look for
its legs. |
Beelicious.
The mantis don't move around very
much. They wait patiently often hanging down under the flowers
until something comes within striking range. |
 |
 |
 |
 |
| Brown
praying mantis. I never saw
this mantis with any prey. He was smaller than the more
seemingly common green mantis |
Assassin bug. There were
several of these on the plants and they all seemed to be dining
on small flying insects. This one captured a large bee like
insect. Other smaller flying insects then surrounded the prey. |
Brown
stink bug or soldier bug? |
Green stink bug.
There seemed to be various shades of
this bug from dark green, to light green and a brownish color. |
 |
 |
 |
 |
|
Unidentified bug. The
bright red on its back made the small bug easy to spot when it
visited the burroweed. |
Unidentified bug. This
little bug with the red rim liked to hide under the flowers. |
Orb
Weaver spider. I thought
this spider was near the top of the food chain because he always
seemed to have something new to eat. However the predator became
the prey and was eaten by a mantis. |
Unidentified
spider. Saw only the dark
legs under a bloom which contrasted nicely with the yellow.
Closer examination exposed the whole spider. |
 |
 |
 |
 |
| Green
Lynx spider. Colorful
little spider I would have missed on a windy morning if it
hadn't moved. |
Unidentified spider. Hard
to spot yellow spider on yellow flowers. One photograph and he
was gone, hiding under the blooms. |
Longhorn beetle. These
beetles can come in a wide assortment of colors but usually easy
identifiable because of the long antennae. |
Longhorn beetles.
The antennae were like whips moving
through the air as these two had a close encounter. A third
beetle was present but decided three was a crowd. |
 |
 |
_small.jpg) |
 |
|
Unidentified beetle or weevil.
There were many of these small
beetle like creatures moving in and out of the blooms. |
Green
Stink bugs. As singles,
these insects were fairly illusive as they hid between the
flowers. Once they began to mate they were exhibitionists and
easy to |
Bird
grasshopper, Schistocerca albolineata
Colorful grasshopper was easy to
spot although he was in the branches near the interior of the
bush. |
Grasshopper love.
There was a lot of grasshopper
piggyback riding although the females seemed more interested in
dining. |
