Every year about this time, customers start bringing in photos of this strange white, fluffy substance on the stems of their shrubs and perennials. I myself have it on the stems of my Rose of Sharon. What on earth can it be? Well, it is not a fungus, as some have suggested. It looks fuzzy, so could it be a mealy bug? Nope. It is an evasive little insect called a leafhopper. I say evasive because if you’ve ever seen one on a stem, as soon as you get close [...]

  The Genista Caterpillar is the caterpillar commonly seen on the new growth of Texas Mountain Laurels. Note, it is ONLY the new growth that they will be found on. This saves us time and money in our control efforts.         Any time Texas Mountain Laurels have new growth emerging, as in the spring and fall, is a good time to protect the new growth by spraying it with either Bt (Bacillis thurengiensis) or Spinosad. These are both Organic solutions to control caterpillars.         [...]

Have you seen the Monarchs yet? Every year, I watch in expectation for the annual migration to pass through our area. I’ve been planting nectar plants all year in anticipation! Most of us have heard about the recent decline in the population of the Monarch, and how the use of herbicide-tolerant crops in the mid-west has limited the Monarch’s larval food plant, milkweed. We now have new information on how important the nectar plants are for the adult Monarch on the long migration to its Mexico breeding grounds in the [...]

Giant wasps sound like something out of a nightmare! Fear not though, the huge yellow and black insects loudly buzzing around are gentle giants that are either slow to sting, or unable to sting, depending on the gender. Although they are Texas-sized, these wasps are not limited to our state, and can be found from Canada to Mexico. Cicada Killers, Sphecius speciosus (Drury), are large, solitary burrowing wasps.  The name ‘solitary wasp’ may seem questionable as Cicada Killers can appear in large numbers, but refers to the fact that they do not [...]

    There are many species of Lace bugs that can become abundant on certain host plants in certain years. (Do not confuse these with “LaceWINGS”, which are bright green, winged beneficial insects. Lacewing larvae eat aphids!) This year we have seen the destructive pest, Lacebug, on Texas Persimmon, Lantana and Elm trees. Watch for them on Azalea, Texas Sage, Pyracantha, Redbud, Bur Oak and Sycamore as well.     Adult lace bugs are 1/8” to ¼” long and appear flattened. The wings are lace-like, and appear clear. Usually a [...]
