Insect of the Month: Robber Fly....Bee, Fly, Bee Fly or Weird Fly? What is this?

In recent months, I have received a LOT of pictures asking for identifications of a strange insect that seems to be pretty common right now. 

It looks like a fly, maybe a bee, maybe a fat dragonfly... perhaps nothing you have ever seen before.  It is actually a fly called a robber fly.

They are predatory insects and some can mimic bumble bees.  While they are loud fliers and scary, they really aren't threatening to humans.  You may not want to pick one up in case it bites, but they don't come after humans to bite.

Robber flies come in a variety of sizes, colors, and looks, but they all have similar "feet", large eyes, and a furry body.

Don't be surprised if you come across one this summer... they sure seem to be the insect of the summer months this year!

2017 All Bugs Good and Bad Webinar Series: Drain Flies, House Flies, and Fungus Gnats

2017 All Bugs Good and Bad Webinar Series: Drain Flies, House Flies, and Fungus Gnats

Event starts: Friday, August 4 at 2:00 pm EDT

Event ends: Friday, August 4 at 3:00 pm EDT

Insect pests marching around our homes can be puzzling to manage.   Especially frustrating is trying to figure out where they are coming from, and their life cycle.  In this webinar, Elizabeth "Wizzie" Brown, IPM Program Specialist, Texas A and M Agrilife Extension will discuss practical tips that homeowners can use to identify and help control the problem pest. Moderated by Hunter McBrayer and Taylor Vandiver, Regional Extension Agents, Alabama Cooperative Extension System. Click here to login as a guest and participate in the live event.   Note: on August 4, the link to the live webinar opens about 15 minutes before the webinar. If you try to log in earlier, you will get an error message.

Cicadas Emerging

When I think of the sounds of summer, the metallic songs of cicadas immediately comes to mind.  Cicadas are starting to emerge and make their way from the soil to the trees to serenade us again.  Last night I heard my first cicada calls, but soon the trees will nearly be deafening at times while they call to each other.

Cicadas spend the majority of their life under the soil.  I'm sure you've heard of the 17 year cicadas, which only emerge every 17 years.  But the most common cicadas are the "Dog Day Cicadas."  Cicadas that become abundant during the dog days of summer and take only 2-5 year to complete their lifecycle (still a amazing long time for an insect!)

During summer, cicadas mate and by the end of summer, lay their eggs on twigs and bark.  The eggs hatch into nymphs about a month later and crawl down to the soil and feed on roots.  Usually they do very little damage as nymphs, but adults can be a nuisance leaving markings when they lay eggs on young trees.  The nymphs spend 2-5 years in the soil before they emerge from the soil, crawl up a tree or other object (like the side of your house), shed their nymphal skin and emerge as an adult.  The nymphal skin is left behind, clinging to the spot they last stood.

The new exoskeleton grows underneath the old exoskeleton, so when they crack the old skin open, the new skin can be seen underneath.  The newly emerged adult cicada will rest for a short period of time, pumping its blood through the wings and allowing the exoskeleton to harden before it flies up into the trees to sing.

Most of us can recognize an adult cicada, but when you get a chance encounter with the nymph emerging from the soil, it really is a sight!

Gnats Driving You Crazy?

You are not the only one!  I have no idea why, but it sure seems like San Antonians are being plagued by gnats.  Most of the issues people are dealing with are fruit flies. Fruit flies are smaller than house flies, and have red eyes.  They appear tan in color and are no larger than an 1/8 of an inch long.  In the photo of small flies above, the fruit fly is on the far right.

Fruit flies are attracted to ripened or decaying fruit and vegetables, but they are also known to breed in drains, dirty mops or rags, recycling bins, trash cans, soil, and other areas of moisture and decaying or fermenting food.

In order to manage fruit flies, you truly have to find the source.  Once you have eliminated the source, its important to keep fruit and veggies either in the refrigerator or a brown bag for a couple weeks or you will attract them back into the home.

If you're still seeing flies, check the drains.  An easy trick is to put tape over half the drain overnight.  If flies are stuck to it, you know they are breeding in the organic matter that lines the drains.  There are drain cleaners that will eliminate that "gunk" using enzymes.  Bleach, boiling water, and other products will only kill the larvae in the drain now; it does not keep the adults from laying more eggs.

If you have potted plants, they may breeding in the soil.  Check by digging, or placing the plant in a small space overnight.  Its easier to re-pot the plant, but at the minimum, don't over water and allow the soil to dry out.

I'm noticing a correlation between the new green compost bins the city has provided us.  Its wonderful that we are composting and reducing our trash, but we are also keeping our rotten food longer in the home, which is attracting and allowing fruit flies to breed.  If this is your issue, remove the food regularly, if not immediately.

Again, finding the main source is the key.  Recently, we had a MAJOR issue in our office.  I'm a little embarrassed to admit, I was the cause!  I had placed an apple in an insect cage and allowed it to rot and ferment.  Removing those rotten apples almost immediately (within a weekend) got rid of the problem!  It may not be as easy as that, but searching for "ground zero" will make your problem less of a problem.
