Explanation of Names
Euborellia arcanum Matzke & Kocarek 2015
arcanum = 'mysterious,' a reference to the unclear origin and manner of introduction into Europe(1)
Adults 20-26 mm(1)
Wingless in all stages.

-Rectangular pronotum is longer than it is wide, with parallel sides
-Yellow legs, no "rings"
-Male gentalia are distinctive

E. peregrina & E. antoni are similar, but pronotum widens posteriorly (also differs in shape of male genitalia and forceps)

FL, likely other southern states. Seems to be introduced, perhaps from the Neotropics (1)
Dark moist places in greenhouses & urban areas, perhaps elsewhere. Specimens in TX have been found under potted plants.
Has been raised on banana pieces and dried Gammarus (1)
Life Cycle
Eggs are smooth and white, ~1x1 mm; 5 instars total(1)
Creates burrows and chambers in soil and emerges at night, retracting food into burrows for consumption. First described in 2015 from specimens in greenhouses/exhibits in Leipzig, Germany, then subsequently found in greenhouses Potsdam, Germany & Vienna, Austria. These individuals may have come from soil/plants from Florida, and the Florida population could have a Neotropical origin as it is likely not native to Florida (Matzke & Kocarek 2015). Much more natural history is described in the excellent Matzke & Kocarek (2015) description online here.
