Cicindela hybrida, tiger beetle. In the first picture you can see a highly magnified spot of the frontleg. This beetle is one of the fastest beetles in the world. This beetle can run 120 times their own body length in a single second. To put that in human terms, we would have to

Started to build a list of fields for the wheat surveys this fall in AB. There are plenty of opportunities for us to sample your field for wheat midge. What's in it for you? I will send you the results from your field after we have processed the samples. DM me for details.

Update: Genetic testing identifies Group 14-resistant kochia at 13 more sites (so far) across the Canadian Prairies and in all three Prairie Provinces. Stay tuned for complete updates this fall/winter…
Is your kochia Group 14-resistant? Find out for free! Help us validate our new genetic test by submitting leaf tissue. This year we have an open call for testing Group 14 resistance in kochia across AB/SK/MB. Contact me for a free sample submission kit. https://t.co/X12PLd0llT

I doubt that you want them so I'm offering to collect them! WANTED for research! live #fleabeetles that might be in your canola crop right now! Also, I'd love to hear reports about the absence of #fleabeetles in your canola right now.

Rhynchites caeruleus. These small, shiny beetles are currently easy to observe. They initially appear black to our eyes, but upon closer inspection, they remind me of liquid metal.
