5 Gifts for the Entomologist in Your Life

Sharing again this Christmas Season...

Are you wondering what to buy the entomologist on your list ....  here are a few ideas that are sure to make your little (or big) entomologist a happy one this holiday season!

1 - Insect Collecting Kit.  Bioquip (bioquip.com) sells a couple of these, ranging from around $42 to $120.  These collection kits have everything you need to collect and mount insects for amateurs to professionals.  Both basically contain the same materials, one is just a better quality and "really fancy".  They have the basics you need: pins, insect net, forceps, a spreading board, and a collection box.

2 -Display Case for Collections.  Every entomologist loves to show off their collections and there are a number of options out there, in various sizes.  Glass covered display cases can be mounted to the wall or placed on tables as art work - everyone loves to look at an insect collection!  Craft stores sell shadow boxes with a fabric backing that insect pins fit into.  You can find these are Hobby Lobby or Michaels.  While these are great to hang on walls because they already have the hardware and are an inexpensive option, they are not air tight, so you'll need to remember to use moth balls or ??? to prevent dermestid beetles from ruining your collection.  Bioquip, hobby stores and scientific stores may carry more airtight boxes.

3 - A Professional Insect Net.  Dinky nets can be found at the dollar store, but a real entomologist needs a good net!  Hobby and science shops and Bioquip sell a range of nets.  You can find various diameters for the nets and various lengths of the stick.My personal favorite is the dual net - they are strong enough to take a beating in some brush, but light enough to catch butterflies out of the air.

4 - A Good Identification Field Guide.  There are soooo many out there!  My suggestion is to try to find one that is local to your region or state.  At the very least, chose a field guide for insects found in North America.

5 - A LIVE TARANTULA!  Every entomologist has some live arthropod they keep as a pet.  You can find suppliers everywhere, even pet stores.  I enjoy shopping from breeders.  They generally know more about the specimen they are selling you and can help you choose the right species for you tastes: something you can handle easily versus something flashy and pretty.  You can find breeders at reptile and exotic shows or online.  My suggestion is to ask to hold the tarantula first - that way you know if you are comfortable with it before you take it home.  You'll also know if its too fast or skitzy for you.
If you are local to San Antonio a good breeder with a variety of tarantula species is Nature's Exquisite Creatures.  Look them up on facebook at https://www.facebook.com/NaturesExquisiteCreatures/

The Incredible Edible Insect Event!

We hope you will join us for our fourth annual Entomophagy event!  This year we are partnering with the San Antonio Botanical Gardens and the Monarch Festival to celebrate eating insects as sustainable source of food!

Bring the entire family!  This will be a family fun, event, with plenty of activities for the kiddos.  We will have face painting, painting with cochineal, cricket race cars, honey tasting and beekeeping and much more!

Admission grants you entrance into the park and all the family friendly activities, as well as a presentation on pollinator gardening by San Antonio horticulturist, David Rodriguez.

For those who want to partake in the 4 course tasting, designed specificially for our event by renounced chefs, the cost is $25 per adult and $10 per child.

Don't worry if you are a little squeamish about eating insects... these are farm raised, specifically for human consumption.  And most recipes incorporate insects into the food... they aren't necessarily the main highlight of the food.  For example, cricket flour (flour with cricket powder for added protein) will be utilized.  Come and join us and add yourself to a short list of individuals who have dined on the delicacy of drone brood and much more!

Hope to see you there!  You can purchase tickets in advance or purchase at the door.  Tickets are limited, however, so we do recommend pre-purchasing. sabot.org

Snout Nose Butterflies Out Again

Snout butterflies are on the loose again in Texas.  If you've been out driving, you have certainly killed one or one hundred, unfortunately. 
American Snout Butterfly, topside of wings.

American Snout Butterflies get their name from elongated mouthparts called palps that extend from the head.  They are small to medium sized butterflies (much smaller than a Monarch, also a bit smaller than a painted lady) and have orange and brown markings.  They blend in perfectly on bark and even flying can appear to be a leaf fluttering in the wind.

Each year, these guys have several generations and population peaks, but their numbers are directly correlated with rainfall and moisture.  This year we had rain at the right times to help their population.  What the rain does is increase the leaves their host plant makes - the spiny hackberry.  With more food, the females lay more eggs in the summer and those eggs hatch and the caterpillars eat the new growth.  The caterpillars can really only eat new growth from the spiny hackberry because its tender enough for them to chew on.

This population explosion we are seeing is a result of those babies (caterpillars) that fed on the tender hackberry leaves that our rains produced.  The caterpillars become pupa and emerging..

I suspect that the small cool snap we had this past weekend also triggered the adults to emerge from the pupa case.... changes in temperature like that often encourages pupa to emerge (a cool trick if you are raising butterflies from pupa and don't have much patience).

I imagine once we get rain this weekend the Snouts will probably get washed away, so they may not stick around for very long.  If we keep a mild fall, you may even see another generation.

Also keep an eye out for Monarchs as they make their way through Texas to Mexico for their annual migration.  We're seeing a few here and there, but right now the Snouts are taking all our attention.

Rain Bad for the Lawn??? Fungal Issues a Major Concern Right Now

Who would have every guessed that rain could be bad for your lawn?  Well, too much rain in combination with other factors can actually cause issues in the turf and we are starting to see this all over the San Antonio area.

Typical Brown Patch Damage.  Photo by Matthew Rogers 


Brown Patch is a fungus typically seen in the fall in warm season grasses such as St. Augustine, Bermuda and Zoysia.  St. Augustine, Raleigh variety is extremely susceptible to Brown Patch, well above and beyond any other type of turf.

Brown Patch arises in susceptible varieties when we have intense rains, high humidity cloudy days, poor soil drainage, compacted soils and over watering.  You've seen it all over town... it just rained for days and sprinklers are still on!  We have extremely saturated soils, so drainage is near impossible, and days and days without sun leads to a perfect storm for Brown Patch to thrive!

What Brown Patch is NOT:
Grubs - its too late in the year for grubs to be actively feeding.  They are fat and happy and full and either already pupa (which do not eat) or getting ready to become pupa.
Chinch Bugs - its far too wet and cool for chinch bugs to have any sort of population that would lead to insect issues.
QUIT BLAMING THE BUGS!!!!

Here's what you can do as a homeowner when you see Brown Patch:

  1. Get it diagnosed by a certified nursery professional or turf specialist
  2. F-Stop Granules by Fertilome.  Found at any nursery or feed store.  There are two application rates on the label.  Use the higher application rate on the bad areas of the grass and lower rate on the rest of the lawn to prevent spread.
  3. Two weeks after you treat with the fungicide, core aerate the lawn.  This will allow for better air circulation, reduce soil compaction, and assist with better drainage.  Be careful with in ground sprinkler systems.
  4. At the end of October, winterize your lawn with an 18:6:12 fertilizer formulation.

Don't forget!  TURN OFF ALL SPRINKERS!!!  We have enough deep moisture to established plants through to March.  Unless we have a a super dry winter, no need to water anymore!  If we do have a super dry winter (no moisture at all, warmer than normal, etc.) water once a month.

Rain = Fire Ants!

In Texas, after a good, soaking rain, we can always expect to see fire ant mounds popping up all over our lawns.  Where were those mounds before?  They were there, just underground and inconspicuous.

Rain is good for many reasons, but one you may not realize is that it helps us see fire ants, gets them active above the soil, and makes them more likely to pick up fire ant baits!

I love using baits to manage fire ants.  They are more host specific, attracting fire ants better than other insects.  Baits (when applied according to the label) usually mean less pesticide out in our environment... and the fire ants like it, so they pick it, gobble it down, and close their eyes forever.

Here are some tips to remember when you are applying the baits:

  1. Make sure the ground is dry and rain is not in the forecast within a 48 hour window.  Just like you don't like to eat wet bread, fire ants don't want to pick up wet bait.  NEVER WATER BAIT IN.
  2. Apply according to the label.  Figure your square footage and apply the proper amount, especially if broadcasting the bait over the yard.  Don't over apply, that can actually make the fire ants avoid the bait.  If in doubt, apply less.
  3. If treating individual mounds (and this is easy when they are visible),  sprinkle the bait around the mound, not on top.  On the mound is not where the foragers are looking for food.  Instead, the bait may be treated as an intruder or trash.
  4. BE PATIENT!  Baits can take up to two weeks to work.  There is a method to this madness... baits aren't eaten by the adult ants (workers and queens).  Larvae eat the bait, partially digest it, regurgitate it, and that it fed to the workers and queens.  And the queens feeding is most important.  Otherwise, you just kill some workers, but she's laying up to 2,000 eggs a day to replace them!
Fall is the fantastic time to do the Texas Two Step Method of Fire Ant Management.  Start with a broadcast bait and then come back for those stubborn mounds with an individual mound treatment.  This is an integrated pest management tactic, decades of proven results in the field and research trials, and uses less pesticide that treating each mound you see with liquid pesticides.

Tree Management Workshop

We still have room in our Tree Management Workshop!  If you are interested in learning how to properly care for the largest and most valued part of your landscape, please join us!  We will cover proper pruning, common insects and their management, general management of trees and latest updates on oak wilt and the emerald ash borer.

Fall Armyworms on the Move...

Dr. Allen Knutson with Texas A&M AgriLife Extension Service put together a wonderful publication on fall armyworms and management options.  If you are like many of us around Texas, experiencing an outbreak of fall armyworm, this publication will be helpful.

Blame it on the rain, making favorable conditions of their eggs and larvae... and with more rain in the forecast, we may still have some weeks on this outbreak. 

Unfortunately in turf situations, it is often too late to treat once they start to make their move.  While this publication is meant for pasture and hay fields, the active ingredients may be helpful for turf.  These are caterpillars and Bt and Spinosad are two good options.  However, Spinosad is a little more stable and will not break down as quickly, which makes it a better option than Bt.

Squash Bugs on the Loose

Squash crops are coming along in backyard gardens this time of year.  Protect your squash from the dreaded squash bug!  Last week, I was out checking on my squash plants, and discovered an adult squash bug, crawling along the leaves.  A quick look under the leaves uncovered a plethora of squash bug eggs.

What did I do?  Squashed the heck out of the squash bug eggs and hoped I killed every last one of them.  Then I took the adult inside and added her to my collection.

Take a good look on the underside of the leaves of your squash plants.  The plants are probably still small enough that this task isn't so daunting.  Even if the plants are large and have a lot of leaves, its well worth the effort to physically smoosh the eggs you find.  Look for brown, egg shaped, eggs in the crotch of veins of the squash leaves.




Squash bugs really like to congregated underneath the leaves and at the base of the plant, where it meets the soil.  Excessive mulch can help increase and aid squash bug populations.  Hand picking works wonders ... if you have the time.  But you can also wrap the base of the plant with foil to irritate the bugs, treat only the base of the plant if you are worried about treating the entire plant, or use a foliar insecticide labeled for veggies, being sure to get underneath the leaves.

Make sure you read that label carefully in case there is a time between treating and harvesting you need to be careful to time

San Antonio Chicken Coop Tour!

What better way to kick of Spring than by a chicken coop tour?!  A new city ordinance for the City of San Antonio now allows you to have six chickens AND a rooster.  If you have ever thought about having your own backyard flock, do yourself a favor and just do it!  You'll never regret it.

Join the tour to get ideas for how coops should be built to protect against predators, size requirements for flock sizes, and other details that you only learn through experience.
