Goliathus Posted February 25, 2022 Report Share Posted February 25, 2022 A small but interesting beetle that I occasionally find; a Bark-Gnawing Beetle, Temnoscheila spp. (family Trogossitidae) - Many species of this genus are metallic green or blue. I was surprised at how readily these beetles will bite when handled, and at how much pressure their mandibles can exert, despite the insect being only around 20 mm long.

INaturalist says these are in my area but I don't think I am looking in the right places. I've mainly found them by attracting them with a UV light.

No idea, but the larvae live under tree bark, and are predatory on the larvae of other beetles, including Scolytinae. Photos of Temnoscheila larvae - https://www.insectimages.org/browse/detail.cfm?imgnum=0745049https://bugguide.net/node/view/41439 In form, they are rather similar to the larvae of some predatory click beetles, such as Alaus spp. Quote Link to comment Share on other sites More sharing options...

JunkaiWangisme Posted March 1, 2022 Report Share Posted March 1, 2022 I heard the larvae can be fed on bean weevil larvae or other grain pests. These are extremely common with funnel traps baited with ethanol, and have a very wide range. At night can be found on bark on trees with seeping sap with extremely good reliability (I have over 100 of these pinned lol, and that's bc I don't keep most that I find). I might try to raise some this year cause I just got a bean weevil colony established Quote Link to comment Share on other sites More sharing options...
