Facts On Ladybugs

Jun-6-2009 By Barbara Zak

Ladybugs are also known as ladybirds.  They are not just considered one ladybug, but a family of them.  There are nearly 5,000 different species of ladybugs, of which more than 400 species are common in North America.

In her lifetime, (usually several months) a female ladybug will lay more than 1,000 eggs. The male ladybug is slightly smaller than the female.  As they age, their spots fade.  Under the right conditions , the Asian Lady Beetle,  can have a lifespan of 2-3 years.

When they fly, they beat their wings on an average of 85 times per second.  However, they won’t fly if the temperature is below 55 degrees Fahrenheit.  They also, don’t like being in direct sunlight and hot temperatures.

It has been said that ladybugs stink.  This is because, if they sense that they are in danger, they can create a chemical smell that both stinks and tastes terrible, so that birds and other predators won’t eat them.  Pretty smart for a little bug.

Their favorite food is aphids, of which they will eat more than 5,000 in their lifetime. No wonder they are so valuable to your garden.  They chew their food from side to side.

It has been said that Red Ladybugs are a symbol of “luck.”  Fact is, we are the “lucky” ones, when ladybugs show up in our gardens and eat our unwanted garden pests!

See where the cutest ladybugs live!

Climate Change Is Real

Jun-19-2008 By Barbara Zak

Tomorrow is officially Summer. But, here in the Puget Sound area, we got gypped out of Spring.  We can count on one hand, well maybe not quite two hands the few days that have come close to 70 degrees.

The truth is, it has been flat out cold.  In this month of June, Fairbanks ,Alaska has already had 10 days above 70. The “Icebox of our Nation,” International Falls, Minnesota has had four days top 70 degrees so far this month.  The mercury has been topping seventy in Oslo, Norway nearly every day recently.

Even Tomsk, Russia, in Siberia was warmer than Seattle on the 10th of June. They hit the 70’s in Siberia and we were still sporting our sweatshirts and hoodies at 55 degrees. The snow plows were back out on Snoqualmie Pass, clearing another 7 inches of snow, just last week. That’s happened only two times in the last 30 years. This has been a record year for snow in our mountains.

We are praying for a slow thaw, or we will be looking at terrible flooding like we had in December. It was the worst flooding here in over 100 years.

Perhaps we shouldn’t complain too loud, at least we don’t have to be looking for relief like they were on the East Coast last week, sweltering at more than 100 degrees in places. Not to mention, an early start to the fire season in California, in April, and an already record number of hurricanes, tornados and severe storms in the Midwest, doing billions of dollars of damage.

According to the U.S. Climate Change Science Program, which is a combined effort of more than a dozen government agencies, we can expect to see more severe and intense weather patterns ocurring. There will be more severe droughts, more disastorous (stormier) storms covering wider and more diverse places,plus more and deeper flooding as part of our changing climate.  Events that are rare to an area, can and will become commonplace. A rise from moderate to high sea surface water temperatures have been linked to increasing power and more hurricane activity.  Last season there were approximately 900 hundred hurricanes, this year they are expecting at least 1800 to pass through the Midwest.  The season started in April, and as evedent by the damage so far, has been relentless.

CO2 emissions have caused the global average temperature to rise 15-60 times faster than the natural historic rate. Our Earth’s climate system is changing more rapidly than some species are able to adapt.  These changes are already affecting more than half of Earth’s wild species.  More than 16% of all coral reefs have become damaged, or even died because of high sea water temperatures. Coral reefs may even become extinct in this century, if we don’t concentrate on controlling and stabelising CO2 emissions.  There is no time to waste on this issue.  It affects all life, even our own.

How’s Your Weather ?

Apr-28-2008 By Barbara Zak

The calendar says it’s Spring , but Winter is still hanging on here in Washington State.  On April 11th, we had one day of eighty degrees. The next day, it was barely above fifty and more rain. We’ve even had Spring snow, twice this month. No, not just a dusting, but inches. Most nights still drop down into the 30’s, and most days have been lucky to see 50 degrees.

Yes it’s true we have always been criticized for our weather here, but it’s usually pretty mild and comfortable. I haven’t seen too many people breaking out their shorts and sandals yet, not here. We haven’t put away our winter clothes yet, or gotten our gardens planted for the most part. It will be no doubt be a short growing season.  The recent snow we had has potentially damaged our apple, cherry, pear, and asparagus crops that are grown in Eastern Washington.  This Winter has brought record snow to our mountains. Two of our ski resorts are still open and it’s almost May. That’s always great news for the skiers, but if we get what we call the Pineapple Express, (warm air  current from Hawaii) like we did in December, we will see more record flooding. 

It is rare that our weather here makes national news. Most recently, it was our snow that made headlines. In December, it was the worst flooding Washington has seen in the last 100 years.  Most areas had 3-5 inches of snow on the ground. The Pineapple Express came through and dumped seventeen inches of rain non-stop in less than twenty-four hours. There are some areas in our state that are still recovering, and locally just last month several road repairs were completed.

It’s not just our weather that is strange though. Over the weekend the Pasadena area had temperatures of 100 degrees and the first wildfire of the season. A couple of months earlier than usual. Today, there were terrible twisters in Virginia. It seems there are few states that haven’t experienced a natural disaster or weather phenomenon, in the last five years. Perhaps Mother Nature is sending us a wake-up call to take better care of our planet. Let’s hope there is still time to change our ways and turn back time. We should have paid more attention thirty years ago to warnings of what could happen. Now our planet is in crisis and Mother Nature is fighting back.
