What is buggin Jim : Caller inquired about giant dragon flyish looking insect-not near water-flying into his garage- here is a possible answer!)





Cicada killers (Sphecius speciosus) are related to mud daubers or dirt daubers on the wasp family tree. They average greater than one inch in length and are recognized by their amber-colored wings and yellow/orange/black bodies. Cicada killers' size leads one to believe that they are aggressive and dangerous. They are frequently seen zooming around just above the grass or soil and sometimes they are observed crashing into windows.



These patrolling behaviors are exhibited by the male cicada killer. Males patrol territories for females and will chase other males away; hence the window-crashing behavior when they see their reflection. Above all of this, male cicada killers do not possess a stinger and, therefore, cannot sting.

So for those who missed this week and want to play next week- Call in next week with this for your answer as to what was "bugging" Jim McMillian!

Here is some information on Tomato Hornworm (see pic)

This home gardener headache is native to the United states, and is commonly found in Missouri. This insect is not a major problem for commercial farms . However the larvae is a frequent problem in home gardens.

Tomato hornworms feed only on the nightshade family which includes tomato plants and all its its relatives including these easy Missouri veggies: eggplant, pepper, and potato.

There are many " weeds" that belong to the nightshade family also including: horsenettle, jimsonweed.

Check weekly for this common garden visitor as 1- 2 generations are reported for this insect each year in Missouri the upper Midwest. Frequent viewing of the garden allows for hand picking as the prefered organic method of control. Many chemicals and even Bt (Bacillus thuringiensis) can kill any butterfly larva in the garden. This insect is parasitized by a number of insects. One of the most common is a small braconid wasp. Larva that hatch from wasp eggs laid on the hornworm feed on the inside of the hornworm until the wasp is ready to pupate. The cocoons appear as white projections protruding from the hornworms body. If such projections are seen, leave the infected hornworms in the garden. The wasps will kill the hornworms when
they emerge from the cocoons and will seek out other hornworms to parasitize.

Listeners- Today's featured insect discussed by Don and Jim was BAGWORM - watch for details on this bug in future posts!
