There are relatively few insects that are active as adults in the late fall and winter months, but one of those groups is winter crane flies (Figure 1).  There are a number of species of winter crane flies in North…

Status of the brown marmorated stink bug The brown marmorated stink bug (BMSB), Halymorpha halys, was detected in soybean fields in several counties of western Kentucky between August and September 2020. This insect is widely distributed and has been established…

A nice good-looking stink bug was observed in western Kentucky on several occasions during mid-July and mid-August this year. Euthyrhynchus floridanus (Pentatomidae) (Figure 1), known as the Florida predatory stink bug, has been previously detected in Kentucky and several northern…

One of the more unusual species to find in gardens is a terrestrial flatworm called the hammerhead worm. This week, I have had two reports of them; one from the mountains of eastern Kentucky (Letcher County), and the other from…

Leafhoppers in Kentucky 2020 Kentucky is not known for its leafhoppers but ask anyone who has been outside this season and they will tell you Kentucky is full of them. Leafhoppers are found all across America but generally do not…

One of the more spectacular entomological events is the emergence of millions of periodical cicadas. What makes this event so unusual is that it occurs so infrequently, each brood emerging every 13 or 17 years. Depending on where one lives,…

A nationwide survey is currently underway to gather information from farmers and growers on the economic impact of the brown marmorated stink bug (BMSB) (Figure 1) on agriculture. The objective of the survey is to better provide commercial producers with…

Stink bugs are becoming more numerous as we move into the mid-summer months; they are feeding on a wide range of agronomic and horticultural crops. Producers are encouraged to be on the lookout for stink bugs and their close relative,…

Millipedes play an important role in breaking down decaying plant matter. These multi-legged arthropods accumulate where there is some moisture coupled with mulch, fallen leaves, or a significant thatch layer. Large numbers of millipedes can appear suddenly to cover sidewalks,…

Since arthropods are cold-blooded animals, temperature plays a major role in their growth and development. There is a threshold temperature for each species; 50oF is that value for many of our common insects. No development occurs when daily temperatures remain…
