Explanation of Names

Euborellia arcanum Matzke & Kocarek 2015

Size

Adults 20-26 mm(1)

Identification

from(1):
Wingless in all stages

legs uniform yellow, no femoral bands
distinctive male gentalia are
E. peregrina & E. antoni are similar, but with pronotum widening posterad (also differs in male genitalia and forceps)

Range

FL, likely other southern states. Seems to be introduced, perhaps from the Neotropics(1)

Habitat

Dark moist places in greenhouses & urban areas, perhaps elsewhere(1); in TX found under potted plants

Food

Has been raised on banana pieces and dried Gammarus(1)

Life Cycle

Eggs are smooth and white, ~1x1 mm; 5 instars total(1)

Remarks

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(1)
