Sphinx Moth caterpillar

When you spend a lot of time outdoors in the garden, you’re bound to run across some interesting things from time to time.

This week I was working around some grapevines. In one area I was cleaning up neglected rose bush pulling out an assortment of weeds including a small wild grapevine. It was there I found the odd-looking, pink caterpillar of a Achemon sphinx moth munching on grape leaves.

The next day I was moving a few small grapevines from one location to another and found two more caterpillars, one orange and the other green. One was another Achemon the other looked to be a Virginia creeper sphinx moth. They are closely related to each other and both are related to tomato hornworms, as you could probably guess that by the horn on their posterior.

It’s been a few years since I’ve seen these even though there are a lot of grapes in our area. I usually have to travel to another area to see them and that was the cases this week.

A pink caterpillar this size really catches your eye. Here the caterpillar's "horn" has shrunk down to resemble an eye.

Because they are so big at this stage, they can eat quite a bit but not enough to do any real harm to the grapevines and harvest size is not affected by their feeding either.They will keep eating and get bigger. In a week or two when they are full size, they will burrow into the soil then form a pupa. There they will stay until next summer when they will emerge as a large moth.

The yellow caterpillar was feeding on concord grape leaves.

If left alone they have the potential to overwhelm a vineyard but their numbers are kept in check by parasitic wasps. Those wasps deposit their eggs into the caterpillar’s body where the eggs hatch. The young wasp larvae then feed on the caterpillar and eventually complete their larval stage of life.

Like a lot of moths, they are only active at night sipping nectar from flowers. Although I’ve only seen a few at night, I occasionally have found them in the morning clinging to a walls near a flower garden. One time I even found one inside, it must have flown in when someone open the door.

I ended up moving the caterpillars to an old, well-established grape vine where I knew they couldn’t do any harm. Once they settled down from all the ruckus, they went back to happily munching  leaves as if nothing happened.

Join the International Monarch Monitoring Blitz

Filed under: Events,Insects — Tags: , , — bob @ 8:20 am

By now I’m sure you know we are in danger of losing the monarch butterfly migration in our lifetime. This critical situation was addressed in 2014 when President Obama met with President Pena Nieto of Mexico and Prime Minister Harper of Canada about it. At that meeting they agreed to “to establish a working group to ensure conservation of the monarch butterfly”. Since then much has been done to encourage research into the habits of monarch butterflies. One such result is the establishment of the annual International Monarch Monitoring Blitz.

This is an event that takes place all across the range of the monarch butterfly that spans large parts of  The United States, Mexico and Canada. The purpose is to try to get a count of the number of monarch butterflies during a small window of time. This year the count started July 28th and runs through August 5th.

Scientists are looking for help during the Blitz, they’re asking for “citizen scientists” to step forward and pitch in for the butterfly count.  It’s simple and fun to participate as a citizen scientist, anyone can do it. All you need to do is count the number of monarchs you see in all stages of the insect’s development; egg, larva, chrysalis and adult and make some observations about milkweed plants. Once you’re done, report your findings online at the Monarch Larva Monitoring Project website.

There's another one! Add him to the tally.

This is only the second year of this international event, so now’s your chance to get started as an amateur researcher. Years from now as the Blitz expands and becomes more well known, you’ll be able to proudly tell your friends you were among the earliest participants.

We’re working on our part of the Blitz right now  and hope you find the time to join in too. It’s a great way to spend some time outdoors while knowing you’re doing something tangible to help save our beloved monarch butteries.

Quilt gardens tour near Elkhart Indiana

We recently visited the Quilt Gardens, a really fun ongoing garden tour in the Elkhart Indiana region.

Volunteer gardeners from that area installed more than a million plants in eighteen gardens. Flowers and colorful foliage plants are arranged to reproduce quilt patterns on a large scale.

Vibrant flowers reproduce quilt patterns.

High temperatures can damage tomato plants

Last week I saw a lot of gardens having problems with tomato plants not producing fruit. When discussing this problem with gardeners, the first thing I hear from them is usually,” I’m growing lots of leaves but no tomatoes”. Then they go on to attribute it to an overabundance of fertilizer of one sort or another.

Nutrient imbalance may cause problems, but this season it is likely due to the extended hot temperatures we had until the break in the weather happened this week.  Temperatures in the mid-nineties can damage tomato blossom causing them to fall off the plant — no blossoms means no tomatoes. This phenomenon is known as “tomato blossom blast”.

Heat damaged tomato blossoms turn brown.

There is really nothing we can do to prevent flower damage when the temperatures are so high except wait it out. Now that the weather has moderated, our tomato plants will start producing more blossoms and setting more fruit.

If another heat wave occurs, it’s likely we’ll see another round of tomato flower blast.

Become a bee helper

Filed under: Bees,Insects — Tags: , , , , — bob @ 2:06 pm

By now, most people are aware of the declining honeybee population. What is not as well know is wild bees are having the same problems.

Wild bees are important because in many instances they are more efficient at pollinating some crops than are honeybees. They are also highly adapted to pollinating wild flowering plants making them an essential part of our ecosystem.

Some commercial beekeepers make a large part of their income by renting hives of honeybees to farmers who grow valuable food crops. Almonds are one example of a crop that requires honeybees to pollinate large plantations of trees. There are now a new breed of beekeepers who are commercially raising wild species such as alfalfa leaf cutter bees and renting them out to farmers. I guess in that case they’re not wild anymore.

So what can we do to help out out little flying friends? We can plant pollinator friendly plants in the garden. We can be be aware not to spray our fruit trees when wild plants like dandelion or dutch clover are blossoming in the orchard. But not everyone has fruit trees or even has space for a garden. Not everyone has the inclination or desire to become a keeper of honeybees either. Or if they did, they may not have the time or resources to spend on a hive of bees

You can however become a beekeeper of sorts with very little effort. Instead of keeping honeybees, you can provide a home for wild bees. Most species of wild bees are solitary. They do not congregate together to form colonies like honeybees. They never will see their parents or siblings unlike honeybees who are surrounded by thousands of family member all pitching in to raise them.

When an adult female solitary bee looks for a place to lay her eggs, she doesn’t look for a hive. Instead she looks for a sheltered spot where the egg will be safe while it is incubating on its own. This is most often a crack or fissure in a tree or even better, an opening made by some other animal such a a hole left behind from a tree boring insect.

 

You can purchase pre-built bee houses like the one shown here. Or make your own, bees are not choosy.

Small bee houses for these solitary bees are available to those who would like to help out our wild bees. These bee shelters come in an almost endless variety but they all have one design feature in common, holes that mimic natural cavities for female bees to lay their eggs. Some designs are not much more than simple blocks of wood with many holes drilled into them. Others use stacked up hollow stems of bamboo to form the shelters. Sometimes a roof is attached to keep the rain out.

You can make your own or buy these bee houses at garden centers or online. Either way it is an easy way to become a beekeeper or at least a bee helper. Unfortunately, solitary bees don’t make honey, they have no reason to.  On the other hand they don’t sting.
